Test: Physical Features Of India- 1 - Question 1

Assertion (A): The Western Ghats are higher in elevation compared to the Eastern Ghats.

Reason (R): The Western Ghats receive orographic rain as moist winds rise along their western slopes.

Detailed Solution for Test: Physical Features Of India- 1 - Question 1

 

  • Assertion (A) Evaluation: The statement that the Western Ghats are higher in elevation compared to the Eastern Ghats is true. The Western Ghats have an average elevation ranging from 900 to 1600 meters, whereas the Eastern Ghats have an average elevation of about 600 meters. This elevation difference is a geographical fact.
  • Reason (R) Evaluation: The reason provided is accurate. The Western Ghats do receive orographic rain as moist winds rise along their western slopes, which leads to significant rainfall in this region. This phenomenon is responsible for the lush greenery and biodiversity found in the Western Ghats.
  • Explanation of Answer: Both the Assertion and the Reason are factually correct. However, the Reason is not the direct or sole explanation of the Assertion. While the elevation difference is a contributing factor to the Western Ghats being higher, the primary reason for their elevated status is not solely due to orographic rain.
