[单项选择]When you are near a lake or a river, you feel cool. Why The sun makes the earth hot, but it can’t make the water very hot. Although the air over the earth becomes hot, the air over the water stays cool. The hot air over the earth rises. Then the cool air over the water moves in and takes the place of the hot air.
