Question 1:C

Question 2: D.

Test analysis:

Question 1: On the contour topographic map, if the contour is closed and the contour value is high in the middle and low around, it is the top of the mountain; The relatively low-lying part between the two peaks is the saddle; If the contour line is closed and the contour line value is low in the middle and high around, it is a basin; The contour line bulges to the lower altitude as a ridge; Contours protrude above sea level and enter the valley; Where several contour lines overlap is a steep cliff. Combined with the diagram: a is along the river; B. Contour lines extending into valleys above sea level; C is the foot of the mountain, which is relatively flat; D where several contour lines overlap is a steep cliff; Combined with the meaning of the question, the campsite requires a flat terrain, away from valleys and rivers, to prevent personal injury caused by mudslides and rising river water levels, so this question chooses C.

Question 2: According to the knowledge of contour lines, it can be judged that ① is a ridge, ② is not a ridge, only a hillside, and A is wrong; According to the principle of "dense and steep contour lines", ① contour lines are sparse and flat, ② contour lines are dense and steep, and B is wrong; According to the figure, the vertical spacing is 40m, the altitude of the highest point is 240-280m, the altitude of point B is 80m, and the relative height between the highest point and point B is 160-200m. According to the vertical drop rate of temperature, when the altitude rises 100m, the highest temperature is 20℃, and the temperature drops by 0.6℃. Because the map scale is 1: 500m, the distance on the map of AC is 1.8cm, and the actual distance is 1.8 * 500 = 900m, D is correct, so D is chosen in this question.
