Why do desert regions receive very little rainfall?

Answer 1

because deserts dont have rivers, lakes, and seas around it.

Correct answer:

Most deserts do have rivers, lakes and some have oceans nearby. Also, all deserts do receive some rainfall but it is usually less than 10 inches per year. What controls the rainfall are the prevailing winds and mountains. Most deserts lie in the rain shadow of major mountain ranges that prevent most atmospheric moisture from reaching them.

Answer 2

The reason that deserts are so dry is because of the low rainfall count. Depending on where they are and if there is any water in the first place in that area (you need to know that because evaporation needs to occur before condensation) , if there is a grand amount of water in the area, then there will be more rain. If maybe there's no water sources at a point (a desert) and there is a place not TOO far away, then if there is enough water in the rain clouds, and ifthe wind direction is moving towards the desert, then rain will come. That is why it is not very likely.
