ONLiNE UPSC · Accepted Answer

Statement 1 is correct: The formation of erosional landforms is influenced by the erosional agent (wind, water, ice), the rock type (hard or soft), and the climate (arid, humid, or glacial conditions). For example glaciers carve U-shaped valleys.

Statement 2 is correct: Coastal erosional landforms such as sea arches, sea stacks, and wave-cut platforms are shaped by hydraulic action, abrasion, and solution.

Statement 3 is not correct: Wind-eroded landforms like Mushroom Tables are characteristic of arid and semi-arid regions, not humid areas. These landforms form due to persistent wind erosion, which removes loose materials, sculpting distinct shapes in deserts and dry landscapes.
