The average depth of the ocean is about 4000 meters, and the deepest part exceeds 10000 meters.
The sea has become shallow. For example, the average depth of Bohai Sea is 18m, and the maximum depth is 70m. The average depth of the Yellow Sea is two or three hundred meters. The South China Sea is quite special, with an average water depth of about 1000 and a maximum water depth of about 5000m (this data is not very clear), which is also the reason why China conducted the first ocean drilling in the South China Sea (because the crust of the South China Sea is closer to the ocean crust, while the East China Sea and the Yellow Sea of the Bohai Sea are close to the continental crust, and the chief scientist of this drilling voyage is Academician Wang of Tongji University. You can go and have a look if you are interested.
Of course, the division of land and sea is also related to the contact of marginal land.

12. Use paper on both sides
13. Garbage should be classified and put in boxes as much as possible.
14. Turn off the lights to save electricity.
15. Promote walking and cycling, and try to take the bus.
Question 3: In order to prevent the world climate from deteriorating further and advocate green life, which of the following related behaviors do you think are not in line with green life? (a) Collecting and uniformly treating waste batteries will reduce environmental pollution, heavy metal pollution and soil pollution. , a mistake; B, don't use disposable products, such as disposable lunch boxes, chopsticks, plastic bags, etc. It can reduce white pollution and meet the requirements of green living. B wrong; C, driving a private car and parents to travel to the seaside during holidays, the carbon monoxide content emitted by automobile exhaust is the highest, which will pollute the environment and meet the requirements of green life. C is correct; D, it is a saving behavior to collect the paper that can still be written and continue to use it, which meets the requirements of green life. D is wrong. So I chose C.
Question 4: Proposal on "Green Environmental Protection, Start with Me" Proposal on "Green Environmental Protection, Start with Me"
In the early spring of 2008, five provinces, municipalities and autonomous regions in southern China/KLOC-0 were successively hit by snowstorms. According to the analysis of authoritative meteorologists, La Nina phenomenon is one of the important reasons for this snowstorm. Nature cruelly tells us once again that environmental protection is urgent! It is urgent to establish a national economic system with low input, high output, low consumption, less emissions and recycling, and a resource-saving and environment-friendly society!
Of course, environmental protection is also inseparable from scientific and technological progress. With the continuous development of science and technology, we look forward to popularizing solar energy, hydropower, tidal energy and wind power generation in the near future; Make the most extensive and full use of natural gas; Try to make seawater desalination possible; A new generation of energy-saving electric light sources has reached a new level; A new generation of building materials that are durable, temperature-resistant, noise-resistant, corrosion-resistant, non-deformable, dust-free and radiation-free will also benefit mankind.
Therefore, in order to make our sky bluer and our water cleaner, to let students firmly establish new environmental protection concepts, new morals and new fashions, to protect our beautiful homeland, and to welcome the 2008 Green Olympics-People's Olympics-Science and Technology Olympics, our students will issue an initiative to all teachers and students on the occasion of "the first science and technology culture festival of Yucai Middle School and the establishment of a national green school": start from me, start from small things and start from yourself. Understand and act mainly from the following aspects:
1. Saving is a virtue: saving every kilowatt hour. Turn off the lights when the last person leaves the classroom, conference room and dormitory. Students should consciously form a good habit of using air conditioning reasonably. Save every drop of water. When using water, turn down the tap as much as possible. Turn it off after use. If water leakage is found, actively notify the school education service department for timely maintenance. The air-conditioned water in the dormitory can be used to wash the balcony floor. Save every grain of rice. Eat as much as you want, and try not to leave any food. It is a crime to waste food. Save every piece of paper. Use textbooks, exercise books and draft paper reasonably. Make the best use of everything, don't throw it everywhere.
2. Reuse of waste materials: all recyclable materials, such as waste paper, waste plastics, waste batteries, waste metals, etc. We should recycle resources by classification as much as possible, so as to save resources and reduce garbage pollution. Therefore, it is suggested that all classes and dormitories should set up waste recycling bins ..... When the recovered funds are accumulated, sports, fitness, art, science and other activities can be carried out.
.
Protecting the environment is ethical: put the garbage in the box and don't throw it around; Take good care of greening and don't trample on the lawn. Every talented person.
Is the owner of yucai,
Be ashamed of littering,
And can take the initiative to fight against uncivilized phenomena,

Question 5: Will 5:XP give full play to hardware performance than 98, thus making the game run more smoothly? As a system that has served for more than ten years, it has ushered in its own home. Now, netizens all over the world can't help but respect this system that has existed tenaciously in Microsoft for more than ten years. Only by continuous exploration, trial and innovation can the system run more humanized. This point is XP can't compare with 7 and 8. 1.
Question 6: Promote a green and low-carbon life (write a few low-carbon suggestions and explain the reasons). Low-carbon life is indeed a rational way of life. In fact, before the industrial civilized society, even decades ago, we lived a low-carbon life, but the advancement of industrialization and urbanization soon pushed human life to a high-carbon life. Of course, a high-carbon life is unsustainable. So how to achieve energy conservation, emission reduction and low-carbon life on the basis of maintaining modern living standards? In fact, low-carbon life is an attitude, not an ability, for ordinary people. We should actively advocate and practice a low-carbon life, pay attention to saving electricity, oil and solar terms, and start from scratch. In addition to planting trees, some people buy goods with short transportation mileage. Some people insist on climbing stairs, some are interesting, and some are hard to avoid trouble. Now let's talk about clothing, food, housing, transportation and economic activities. The first is "clothing". Everyone knows that young people like to wear jeans. In fact, jeans are the least "low carbon". As far as the processing of denim is concerned, it not only consumes a lot of water and electricity to polish, but also extracts various chemical dyes with high carbon emission, which has a certain degree of * * * effect on the skin and is easy to cause allergic dermatitis, itching, pain, redness or blisters. In addition, the clothes made of chemical fiber fabrics have poor air permeability and hygroscopicity, which affects sweat evaporation and skin breathing, and is also easy to absorb dust in the air. Therefore, we try to choose less chemical fiber products as close-fitting clothes to wear. In addition, in the choice of fabrics, you may wish to choose some "low-carbon" materials, such as cotton, linen, silk and other natural fabrics, and try to avoid choosing clothing with chemical fiber texture. The second is "food". As we all know, pork and muscle are produced by large-scale consumption of food. China consumes more than half of the world's pork and chicken every year, and the food consumed to produce a catty of pork or chicken is more than five times that of the world. If everyone goes to eat pork and chicken, it will hinder the development of this industry, which is actually a completely wrong route. 70% of the development of animal husbandry abroad is herbivores, not food-eating animals. Therefore, the choice of meat in life should be mainly herbivores, such as cattle and sheep, plus some fruits and vegetables, and don't eat too much meat transformed from grain. To sum up, it is necessary to achieve a balanced diet and change the habit of emphasizing meat; Eat less junk food and more fruits and vegetables. The third is "living". You should try to live in a residential building with a small area and many walls, so that the walls of this house can also transfer heat and make the room warmer. If you live in a villa, it is ventilated on all sides, so the energy consumption of the villa is very large. In addition, in the use of building glass, try to use double-layer glass, or stick a one-way radiation film on the glass to prevent the collected light from spreading out quickly after reflection, because the heat insulation layer of the house is well done, which is equivalent to saving half of the energy supply. In terms of house decoration, most of the decoration materials still have different amounts of harmful chemicals. Too many decoration materials lead to comprehensive concentration of pollution, which is difficult to dissipate for a long time. In addition, processing materials requires energy. In the era of low carbon, we should choose suitable apartments according to the number of family members and reduce the consumption of water and electricity, which not only reduces carbon dioxide emissions, but also saves money. Interior decoration should be based on the principle of simplicity, natural ventilation and lighting, and should not be over-decorated. Put more green plants in the house to absorb carbon dioxide, make oxygen, adjust the air and eliminate odor. The fourth is "line". If you use a private car, the private car itself weighs one or two tons, plus the heat loss of the engine. Even if five people don't have a car, 15% of the good energy of a car will be really utilized, and most of it will be lost. So it is a real waste and a huge crime for a person to drive out. Therefore, in daily life, we should walk more, take fewer cars and climb as many stairs as possible, which can not only exercise, but also help to reduce carbon. Long-distance office workers try to choose cars with low fuel consumption and more environmental protection and take public transport. Walking to work can strengthen the body, enhance cardiopulmonary function, improve blood circulation, enhance daily appetite, prevent and treat cervical diseases, promote bone strength, avoid osteoporosis, exercise double arches and prevent venous thrombosis. In addition, exercise should choose natural and healthy outdoor exercise instead of relying on electric fitness equipment; It should be carried out with moderate intensity so as not to feel laborious. This is both carbon reduction and health care, killing two birds with one stone. The fifth is economic activities. Traditional firewood and stoves are still used in many areas of our country. Burning straw with dry cow dung as fuel in southern Gansu wastes a lot of energy and resources, which is not conducive to low-carbon development. & gt
Question 7: Green environmental protection, low-carbon emission reduction and green life.
June 5th is the annual World Environment Day. The theme of China World Environment Day this year is "Low carbon emission reduction?" "Green Life" aims to advocate the public to practice green consumption, actively promote the construction of ecological civilization, and strive to achieve clean, safe, green and sustainable development.
With the continuous rise and development of modern China, our country's economy has gradually become stronger, and the living standards of our people have been greatly improved. However, in the process of economic development, there are also many problems in our country, the most deadly of which is our environmental protection, which has seriously affected the sustainable development of our country. In order to help people know more about environmental protection, make people pay more attention to environmental protection in their lives, and form good habits of environmental protection, this is of great help to our country.
Through the training on environmental protection some time ago, I learned the so-called "low carbon life". Is to minimize the energy consumed in daily life and work and rest, thereby reducing carbon dioxide emissions. Low-carbon life is a life attitude of ordinary people. It has also become a new way for people to push the trend. This gives us a question, whether we are willing to work with you to create a low-carbon life. We should actively advocate and practice a low-carbon life, starting from the small things around us.
1, turn off the computer in time.
Statistics show that 75% of the electricity in the home is spent on keeping the TV, computer and stereo on standby. On average, a desktop computer consumes 60 to 250 watts a day. If a computer is used for 4 hours every day and turned off at other times, it can save about RMB in 500 yuan and reduce carbon dioxide emissions by 83% every year.
2. Take more buses
Carbon dioxide produced by transportation accounts for more than 30% of greenhouse gas emissions, and one of the best ways to reduce such emissions is to take buses. According to the data of American Public Transportation Association, public transportation saves nearly 5.3 billion liters of natural gas every year, which means that it can reduce carbon dioxide emissions by 6.5438+0.5 million tons.
Step 3 choose a small house
People yearn for big houses, but big houses will increase carbon emissions invisibly and need more energy for heating and cooling. Taking heating as an example, a big house needs to consume a lot of energy to maintain its temperature. The bigger the house, the greater the impact on the environment. At present, every household in the United States emits an average of 18 tons of greenhouse gas every year, consuming a lot of fuel and non-renewable energy.
Step 4 open the window
We emit about 25 tons of carbon dioxide per capita every year. How can we reduce this number? There are some simple and effective methods: opening windows instead of indoor air conditioning; When air conditioning is used in summer, the temperature rises slightly by several degrees. Statistics show that as long as everyone turns up the air conditioner by one degree, the country can save 3.3 billion kWh of electricity every year.
5. Bring your own shopping bag
More than 500 billion plastic bags are consumed worldwide every year, of which less than 3% can be recycled. Plastic bags are all made of polyethylene, which will take thousands of years to biodegrade after being buried, and during this period, harmful greenhouse gases will be generated. Don't forget to bring your shopping bag when you go to the grocery store next time.
Step 6 plant a tree
When it comes to global warming, don't be alarmed if you don't know the complicated carbon capture (CCS) technology. In fact, the experts who "capture" carbon dioxide are the trees themselves. If you think it's too much trouble to plant trees yourself, you can at least donate money to environmental protection organizations and ask them to help you.
Development is the eternal theme pursued by human society. The development of human civilization has always been struggling in the process of constantly coping with and overcoming various contradictions between people, people and nature, and people and society. Due to the intensification of the contradiction between man and nature, development has encountered unprecedented obstacles, which has aroused people's understanding of environmental problems and further explored new development paths. Especially in response to the impact of the international financial crisis, many countries have highlighted the concept and connotation of "green" and implemented the "green New Deal" to plan the development in the post-crisis era. It is generally believed that developing green economy can not only save energy and reduce emissions, but also make more effective use of resources, expand market demand and provide new jobs, which is an important combination of environmental protection and economic development. Promoting green development has brought pressure and opportunities to environmental protection.
If all of us have the concept of green environmental protection and really implement it in our lives, it should be a wish that can be expected and realized to give the next generation a beautiful earth with green mountains and green waters.
Question 8: How to write a proposal on advocating a low-carbon life? 10. Hehe, the copy upstairs is really good. It's a pity that you don't have a specific analysis. People are asking to write a proposal about green living.
Uh, back to the point.
First of all, you should tell others what a low-carbon life is at the beginning of the proposal, that is, "what it is".
Secondly, you need to write about the importance of life in a low-carbon life, that is, "why", which is very important and the focus of your proposal. If you can't convince others here, it will be a failed suggestion.
Finally, you should tell readers what to pay attention to, what to do and what not to do if you want to live a low-carbon life, that is, "how".
What's left, date and how to write it? It has been made clear upstairs, so I won't copy his answer.
Question 9: Save intensive resources and advocate green life. Hello ~!
I found some information for you, all arranged according to what you want.
Under the comprehensive understanding,
I hope it helps you ~! !
1 "Low-carbon life" is a new concept, but it is an old problem of sustainable development in the world. It reflects the worries about the future caused by climate change. Climate problems such as global warming force mankind to consider the current ecological environment. Humans realize that excessive carbon emissions in the process of production and consumption are one of the important factors that cause climate problems, so to reduce carbon emissions, we must optimize and limit some consumption and production activities accordingly. "Low-carbon life" refers to reducing energy consumption in daily life as much as possible, thus reducing carbon dioxide emissions. The concept of "low-carbon life" also conforms to the prudent principle of "preparing for a rainy day" and the psychology and ideal of pursuing perfection. "Low carbon life" tells people what you can do to reduce carbon emissions.
Low carbon is a living habit, and saving all kinds of resources around you is a natural habit. As long as you are willing to take the initiative to restrain yourself and improve your living habits, you can become a low-carbon family and an environmental expert. Of course, low carbon doesn't mean that you should be frugal and give up some enjoyment of life. Low carbon does not affect health and quality of life. As long as we can save more and not waste, we can also live a comfortable "low-carbon life".
Low-carbon life is an attitude, not an ability for us ordinary people. We should actively advocate and practice low-carbon life, pay attention to saving electricity, oil, solar terms and water, and start from scratch. Some people say that in the process of reducing carbon dioxide emissions, "ordinary people have the power to change the future", and now this power is subtly changing our lives. For example, a colleague of mine has been carrying water cups and chopsticks with him since last year. He said that this is not only hygienic, but also reduces the use of disposable cups and chopsticks. For example, fishing on weekends, a fisherman said that he spent fifty cents a week. He goes to work by bike, eats at home and spends only fifty cents by bus. Low-carbon life represents healthier, more natural and safer, and it is also a low-cost and low-cost lifestyle.
Reducing carbon emissions is everyone's responsibility. For us, lifestyle describes everyone's "carbon footprint", that is, how much carbon dioxide is emitted by producing, using and consuming something. Low-carbon life is a simple way of life, which is reflected in all aspects of clothing, food, housing, use and transportation. There are many low-carbon role models around me, and I have some low-carbon living habits myself. For example, I seldom use air conditioning in summer, and try to print documents on both sides. For example, I thought of a low-carbon life last night. Eat vegetarian food for dinner and pay attention to saving water. I didn't watch TV or turn on the computer, so I went to bed at 9 o'clock. Ha ha. In my opinion, a low-carbon life means not pursuing material life excessively. In today's impetuous society, low carbon can bring peace of mind. In fact, low-carbon life is also a low-key life.
2. I really didn't pay attention to environmental protection before. I'm not in the habit of turning off the appliances after I use them. Sometimes people don't know where they are, and the computer is always playing music. As long as the mobile phone battery is plugged in, it seems to be attached to the 502. There is no battery. I don't remember the battery being plugged in. Not to mention the air conditioner, which keeps the temperature to a minimum all the time. I hate it when I get home without frost.
After reading the low-carbon life, I found that carelessness in these details not only brought hidden expenses to families, but also seriously emitted carbon dioxide. Although the trace is very small, the harm of gathering together should not be underestimated. It turns out that even a small cell phone battery will emit terrible carbon dioxide when it is plugged into the socket when the appliance is on. As long as you are charging, you should take out the battery immediately. Originally thought, carbon dioxide was only emitted by automobile exhaust and coal combustion. Unexpectedly, there are weak "carbon" everywhere in our lives to infringe on our lives and the earth.
Knowing this, I will start my own low-carbon Lohas life in the future! Develop the habit of turning off the power at will; Use air conditioning as little as possible; Use walking instead of transportation; Reduce some energy consumption in life to the lowest possible state, and minimize the carbon dioxide emissions of the culprit.
As we all know, our current life pays attention to "low carbon", and the low carbon lifestyle we advocate refers to saving water, electricity, fuel and solar terms. But you can't just talk without doing it.
We should show it with practical actions. But how can this "low carbon" life be "low"?
How low can it be? Let me introduce some low-carbon tips to you.

Question 10: Advocating Green Life and Building Ecological Civilization * * Speech Advocating Ecological Civilization and Building Green Homes. Improving the ecological environment, improving the efficiency of resource utilization and moving towards the harmony between man and nature is a brand-new concept of a well-off society in an all-round way. "Protecting the ecological environment means protecting our rice bowls." "We want not only Jinshan Yinshan, but also green mountains and green hills. With green mountains and green hills, there will be Jinshan Yinshan for sustainable use. " This is a widely circulated language among Ankang people, which shows that Ankang people attach great importance to ecological environment protection. Building a well-off society in an all-round way requires the ideological and moral quality, scientific and cultural quality and health quality of the whole nation to be obviously improved, and ecological moral education should be a part of ideological and moral quality construction. Let "ecological morality" be constructed, let the concept of "harmony between man and nature" be deeply rooted in people's hearts, and let "respecting nature and protecting ecology" become the conscious action of the whole people.
Spring is striding towards us, and the grass is getting a little green. Pear blossoms and apricot blossoms quietly bloom, and peach blossoms bloom beautifully in March! Let people see and feel the vitality brought by spring. Keep this beautiful scenery. We call for advocating ecological civilization and building a green home. Let's work together, shoulder the social responsibility entrusted by history, make positive contributions to the harmony between man and nature, create a better future, and make a better tomorrow for Ankang.
