Question

A rain- shadow region gets:
a. A large quantity of rainfall
b. Rainfall six months in a year
c. Rainfall all through the year
d. Scanty or no rainfall

Answer 1

Hint: A rain shadow area is situated on the leeward or the downward side of the mountains, and the topographic barrier, like a mountain, causes the winds to lose their moisture as they travel up to the mountain. In India, an example of a rain shadow area in Ladakh.

Complete step by step answer:
A large quantity of rainfall: In orographic rainfall, the windward slopes receive a larger quantity of rainfall, as moisture-filled air, rises up, gets condensed, and reaches a saturation point. The excess moisture precipitates upon the windward slides.
Rainfall six months a year: The orographic feathers of a region that allows the place to receive 6-month long rainfall is either situated in the windward side, or on the equatorial regions that last for a very long time.
Rainfall all through the year: Certain orographic features allow some places like Mawsynram and Cherrapunji in Meghalaya to receive rainfall throughout the year. These are the wettest places in the world. They received an average annual rainfall of 1187 cm per annum.
Scanty or no rainfall: In orographic rainfall, as the windward slopes receive all the moisture-laden rainfall, and when these winds reach the leeward side or the other side the slopes receive scanty or no rainfall. This area with no or less rainfall is known as the rain shadow area.
So, the correct answer is Option D.

Note: The leeward side of the mountain receives less rainfall, while the windward side of the mountain receives high rainfall. The leeward side is also known as a rain shadow area. It is associated with the orographic type rainfall.
