Consider the following statements about rainfall in the Himalayan region:
- The Western Himalayas receive more rainfall than the Eastern Himalayas due to the monsoonal winds.
- Orographic rainfall is a significant reason for the high precipitation in the Eastern Himalayas.
- The Trans-Himalayan region, like Ladakh, experiences abundant rainfall throughout the year.
- Rain shadows are areas in the Himalayas that receive reduced rainfall due to the obstruction of moist winds by the mountain ranges.
How many of the above statements is/are correct?
Only One
Incorrect AnswerOnly Three
Incorrect AnswerAll four
Incorrect AnswerExplanation:
Statement 1 is incorrect: The Eastern Himalayas, especially regions like Arunachal Pradesh and Sikkim, receive much more rainfall than the Western Himalayas. The monsoonal winds from the Bay of Bengal are the main reason for this high rainfall in the eastern parts.
Statement 2 is correct: Orographic rainfall occurs when moist winds are forced to rise by mountain barriers, leading to condensation and precipitation. The Eastern Himalayas, with their high peaks, facilitate a significant amount of orographic rainfall.
Statement 3 is incorrect: The Trans-Himalayan region, including areas like Ladakh, lies in the rain shadow of the Himalayas and therefore receives very little rainfall throughout the year.
Statement 4 is correct: Rain shadows are areas that are shielded from rain-bearing winds due to the physical obstruction of mountain ranges. The leeward side of the Himalayas, such as the areas behind high peaks, are rain shadows and thus receive less rainfall.
