Which is the correct difference in origin between mountains and plateaus in Indian physical geography?
Answer and explanation
Correct answer: The Himalayas formed by compression and the Deccan is a lava-related plateau
The governing concept is geological origin. The Himalayas are young fold mountains formed when the Indian Plate moved northward and compressed sedimentary layers against the Eurasian Plate. The Deccan Plateau, in contrast, is strongly associated with extensive basaltic lava flows that cooled and accumulated over geological time, producing the Deccan Trap landscape. Hence option A correctly contrasts compression-related mountain building with lava-related plateau formation. Option B assigns completely unsuitable coral and glacial origins. Option C reverses the accepted age and type: the Aravallis are among the ancient mountain systems, whereas the Himalayas are young fold mountains. Option D misidentifies both Ghats.
