Show answer & explanation
Correct answer: C
Explanation
Solution: The correct answer is Western Ghats are higher in elevation and more continuous than Eastern Ghats.
Explanation:
☛ The Western Ghats are significantly higher in elevation than the Eastern Ghats, with an average elevation of about 900 to 1,600 metres compared to the Eastern Ghats' average elevation of around 600 metres.
☛ The Western Ghats are continuous and can be crossed only through specific passes such as Thal Ghat, Bhor Ghat, and Pal Ghat.
☛ In contrast, the Eastern Ghats are discontinuous, irregular, and dissected by major eastward-flowing rivers like the Mahanadi, Godavari, Krishna, and Kaveri draining into the Bay of Bengal.
☛ Western Ghats cause orographic rainfall by intercepting the rain-bearing South-West monsoon winds along the western slopes.
