Why it rains less in deserts?

Answer 1

IN deserts it doesnt rain coz there isnt any high mountains to block the winds with moisture, the soil is sandy,so water is drained or evoparated,the rocks are of non porous type , the moisture laden winds which reachs from the sea is already emptied and only dry winds blows,these could be some of the factors to make a place dessert.Moreover, the sand loses/gains heat/coolness easily .

Answer 2

It's easier to understand if you revert the causality: where it rains little, deserts develop :-)

But this leaves the question why some areas get very little rain. An example: The coast of Peru get's very little rain because the wind comes from the East. The Andes mountains squeeze the moisture out of the clouds before they come so far - the rain falls on the East side of the mountains.

Answer 3

It is because all the rain goes where that there is plant's, and thus those areas arn't called deserts and deserts are called deserts because they don't have any plant's (which is caused by no rain).

Conclusion: Deserts are caused by less rain. Less rain is not caused by deserts.

Answer 4

Had it rained there, the area would not have become desert in the first place.
Temperature, trees,forest,location of the area ie wrt sea and mountains, and many other factors affect the rain in totality.

Answer 5

Deserts don't have much vegetation. there are less amount of trees n even less water bodies so the water doesn't get evaporated by transpiration n even coz of less water bodies. n so as the evaporation is less the presipitation is also less n therefore desert's don't experience much rains.

Answer 6

a deserted area is one where living matter is sparse (not zero but sparse) and such areas are desertified by lack of rain in case of hot deserts or lack of evaporation in case of cold deserts like antarctica

Answer 7

These are the possibilities why there is little amount of rainfall in deserts: a.) little vegetation within the area which result to lesser evapotranspiration rate b.) little or no water reservoir within the area which gives little or no evaporation rate.... =)

Answer 8

Because if it rained more then it would support trees (or whatever else) and it wouldn't be a desert. Duh!

Answer 9

coz it rains heavily each time....there focus 'quality' not 'quantity'.... :P

Answer 10

coz it is a desert.....
