Question

If height of western ghats decreases from north to south then why are tallest peaks in south

Answer 1

In the Aryan times, the western ‘flank’ of the peninsular plateau developed a normal fault & the western ‘part’ of the western flank subsided under water (the remaining western flank appearing as a horst or a block mountain). This was followed by two successive tilts of the remaining flank (due to tectonic reasons),

i) firstly, an eastward tilt

ii) then a Northward tilt.

This is the reason why WGs have a general elevation from North to South

Answer 2

Topography and wind play an important role in the distribution of precipitation. The terms Ghats is derived from Hindi which means “river landing stairs” or “mountain pass”. The Ghats, which mean Western and Eastern Ghats, are two mountain ranges forming the eastern and western edges, respectively, of the Deccan plateau of peninsular India.
