Western ghats (WG), a.k.a Shyadri, roughly coinciding with west coast (WC) of peninsular India and facing the Laccadive sea, is a 1300 km long and nearly contiguous (but for the Palghat gap in Kerala) wall-like mountain, characterized by rather steep-western-slopes interrupted only by a step-like-aspect (hence the name ghats) in the cross profiles. Stepped-cross-profiles are indicative of multiple planation surfaces (i.e., due to repeated rejuvenations or uplifts) of varying geological ages. The WC is marked by a relatively straight and long shoreline flanking the WG escarpment, which is roughly 100 km away from the modern shoreline
