6. Tuscany, north-central Italy
In Tuscany, southern Italy, there are a group of ancient hot springs. Geothermal formation is named after the Roman god Saturn, and mineral mixed spring water provides relaxation and good existence. Rich hot spring water helps to promote breathing, reduce various skin problems, and play a role in deep sterilization and cleaning.
After decades of filtration, the water quality of hot springs has had a special impact through the caves in Monte Carlo (lava dome in southern Tuscany). Hot water flows out at a constant temperature of 800 liters per second, 37.5 degrees Celsius. Sulfur, carbon, bicarbonate salinity, hydrogen sulfide and sodium sulfate are the main dissolved substances in water.

4. Mammoth Hot Springs in Yellowstone National Park, Wyoming, USA
Mammoth Hot Springs is one of the main geothermal activities in Yellowstone National Park, Wyoming, USA. It was formed by thousands of years of volcanic activity. Unlike other hot spots in Yellowstone National Park, limestone mine is produced by limestone dissolution. Rain and snow are the main water sources of Mammoth Hot Springs, and the groundwater is heated and rises to the surface through the action of subsurface magma chamber.
Mammoth hot springs contain about 50 hot springs, and a large amount of water gushes out of the water every minute. The formation of terraces is another remarkable feature of this site. This thick sedimentary rock is produced by hot water from hot springs. It is the largest known sedimentary rock spring in the world.
3. Iceland Blue Lagoon
Blue Lake Hot Spring is the most popular scenic spot in Iceland. Every year, the blue lagoon attracts more than 500,000 tourists. It is located in the lava area of the town of Green Davic on the southwest coast of Iceland. It is actually an artificial lagoon, and the spring water in the pool is the direct result of the foundation stone laying of Svartsengi thermal power station.
This swimming pool was built in 1976 to store water from geothermal power plants. 1992, Blue Lagoon opened its swimming pool after discovering the healing power of geothermal water. The Blue Lagoon has 6 million liters of geothermal seawater, and the temperature of mineral-rich seawater is between 37 and 39 degrees Celsius. Silicon dioxide and sulfur are the main dissolved minerals in the spring water of Blue Lagoon, and the milky white of water is caused by silicate minerals.
The silica mud in the blue lagoon has the ability to cure many skin problems. Every 40 hours, there will be geothermal water in the lagoon to ensure the purity of the water. The Blue Lagoon also provides water massage, beauty care, spa and tour guide services.

The site was approved by UNESCO on 1988.
Mukkale has 17 hot springs. The temperature of the spring water ranges from 35 degrees Celsius to 65,438+000 degrees Celsius. Containing calcium salt and carbon dioxide, gray limestone deposits are continuously formed during the decomposition of the spring. Hot water will also be collected in terraces. Mineral-rich water also has the ability to cure various skin and eye diseases. The site also includes the remains of the ancient city of Hilapolis.
1. The Great Prism Spring in Yellowstone National Park, Wyoming, USA.
The Grand Prism Hot Spring is one of the top ten most beautiful tourist attractions in America. It is located in Yellowstone National Park in Wyoming. Hot springs are named for their striking colors. Its center is vibrant blue sea water, surrounded by bright colors, including red, orange, yellow, blue and green. The color of hot springs is actually caused by the action of cyanobacteria, which can thrive in hot water, but they do not appear in the central pool because of the extreme heat.
The color formed by cell bacteria also depends on temperature. In summer, people find that the colors of large prismatic springs are orange and red. Next winter, the color will turn dark green. During the thermal activity, the hot spring discharges 265,438+000 liters of water per minute, and the temperature of fresh hot water is between 63.3 and 86.5 degrees Celsius.
