The figure below shows the contour distribution of an island. Read the figure and answer the following questions.
Subtitle 1: The relative height of residential areas P and Q in the figure may be ()
A. 300m
B. 600m
C. 900m
D. Topic 2 of 1200m: The precipitation in cities A and B is similar in summer, but differs greatly in winter. The main influencing factors are ()
A. Atmospheric circulation and topography
B. Atmospheric circulation
C. Land and sea location, topography
D. Current, sea and land position
Subtitle 3: The environmental population capacity of region A is larger than that of region B. From the perspective of natural resources, the closely related factors are ()
① Cultivated land resources ② Fresh water resources ③ Forest resources ④ Mineral resources
A.①④
B.③④
C.②④
D.①②
Best answer:
Subtopic 1: C
Subtitle 2: A
Subtitle 3: D
Answer analysis:
Subtitle 1: The contour interval in the figure is 300 meters. Therefore, the altitude of P is between 1200 meters and 1500 meters, and that of Q is between 300 meters and 600 meters. Therefore, the relative height of P and Q should be between 600m and 1200m, so C is selected.
Subtitle 2: According to the longitude and latitude position, the area shown in the figure is an island located in the North Atlantic Ocean. This latitude is controlled by the subtropical high in summer, with less precipitation; In winter, city A is located on the windward slope with more precipitation, while city B is located on the leeward slope with less precipitation. Therefore, A
Subtitle 3: Land A is located in the coastal plain, with flat terrain, which can be affected by the westerly wind blowing from the sea, and has abundant precipitation; However, land B is located in the mountains and is blocked by the terrain, so the westerly wind from the sea cannot reach it, so the precipitation is less. Land A is richer in land resources and fresh water resources than land B, so D
Test core:
Topographic profile: the vertical profile of terrain exposed by cutting down a certain profile line of the contour topographic map. It can directly reflect the topographic relief along the section line above the ground.
