UPSC NDA-1 – 2022
The correct answer is D) Ladakh.
Moraines, eskers, and outwash plains are all glacial landforms. Moraines are accumulations of glacial debris, eskers are long, winding ridges composed of stratified sand and gravel deposited by glacial meltwater streams, and outwash plains are broad, flat areas of gravel, sand, and silt deposited by meltwater streams flowing from a glacier. Ladakh is a high-altitude desert region in the Himalayas with significant past and present glaciation, making it a place where these landforms can be observed.
Andaman and Nicobar Islands, Lakshadweep, and Puducherry are all located in tropical or coastal areas with no significant glacial history or present-day glaciers.
