Why do mountain ranges create rain shadows???

Answer 1

That is a perfect example of relief rainfall,Mountains cause warm moist air to rise as the air rise temperatures fall creating clouds,as it rises further, moisture that was water vapor condenses into droplets that falls as rain, as it gets too heavy to remain buoyant at a very high altitude.
As the air(clouds) makes it over the range or peaks and descends to the other side,it encounters warmer air that causes it to do the opposite,and further more it has lost most of its moisture,causing it to be less dense.
Normally the side of a mountain that receives more rain fall from prevailing winds is called the windward side of the mountain,and the other side that is drier is its leeward side.

Answer 2

As air is pushed over a mountain range, it rises and cools. As it cools, any water in it is condensed and falls as rain on the front side of the mountains. As the air moves lower on the other side of the range, it contains less water, and the water won't condense and fall...Thus, the rain shadow.

Answer 3

becuse the mountains push the cload upwards and the cload chills and condenses the water and the rsasin falls on one side oif mnt and then the cload gos dry to the other side
