Question

A rain shadow zone is present in India ___________.
A. along eastern flanks of the Aravallis
B. along the eastern slopes of the Western Ghats
C. along the western slopes of the Eastern Ghats
D. along the northern flanks of the Vindhyas

Answer 1

Hint:
1. A rain shadow is a patch of land that has been forced to become a desert because all plant-growing, rainy weather has been blocked by mountain ranges. Wet weather systems will drop rain and snow on one side of the mountain. All the precipitation is blocked on the other side of the mountain-the rain shadow side.
2. An area with relatively little precipitation due to the effect of a topographic barrier, especially a mountain range, which causes the prevailing winds to lose their moisture on the windward side, causing dryness on the leeward side.

Complete solution:
In India, along the eastern side of Sahyadri on the Deccan plateau, the rain shadow zone is present, e.g. The Northern Karnataka & Solapur Plateau of India, Beed, Osmanabad, and Vidarbha.

Rain-bearing winds that cause rain on the western slopes are blocked by the Western Ghats. The Western Ghats are located in the rain-fed zone of the south-western monsoon branch of the Arabian Sea, while the Eastern Ghats are located in the rain-shadow area of the south-western monsoon branch of the Arabian Sea.

Orographic means the mountains are connected to it. They have lost much of their moisture by the time the winds make it across the Western Ghats and very little falls on the Deccan Plateau to the east of the Ghats. This decreased rainfall is called a RAIN SHADOW EFFECT on the leeward side of the mountains (away from the wind).

Option A is not the correct answer eastern flanks of the Aravallis is not a rainshadow area
Option B is the correct answer is eastern slopes of the Western Ghats a rainshadow area
Option C is not the correct answer is the western slopes of the Eastern Ghats not a rainshadow area
Option D is not the correct answer the northern flanks of the Vindhyas is not a rainshadow area

Hence, the correct answer is option .

Note:
1. The Western Ghats, also known as the Sahyadri, is a mountain range covering an area of 160,000 square kilometres, covering an area of 1,600 kilometres parallel to the western coast of the Indian peninsula, crossing Tamil Nadu, Kerala, Karnataka, Goa, Maharashtra and Gujarat states.
2. In west-central India, the Vindhya Range is a complex, discontinuous chain of mountain ridges, hill ranges, highlands and plateau escarpments. In geological terms, the Vindhyas do not technically form a single mountain range.
