Differentiate the causes of landslides in the Himalayan region and Western Ghats.

What a top answer must contain

These are the checkable specifics from the marking standard for this question — the actual case, committee, datum or thinker, not an instruction to “give examples”.

  • Himalaya: tectonic youth (seismicity), fractured lithology, snow-melt saturation, road-cutting — deep-seated failures
  • Ghats: deep lateritic mantle over hard basement, monsoon cloudbursts, plantation and quarry land-use — shallow debris flows
  • Shared anthropogenic layer distinguished from geological drivers explicitly
  • Named contrasts: Chamoli/Kedarnath vs Malin/Puthumala; a two-column figure earns presentation credit
