Answer 1

As air rises, it cools, which means its capacity to hold water vapor decreases. So as wind blows over a mountain range, a lot of the water can be squeezed out, forming clouds or even falling as rain. Then the wind goes down the other side, becoming warmer and dryer. So the land downwind is in the “rainshadow” of the mountain range.
