Answer 1

Answer:

• Since ancient times the vast glaciated heights have attracted the attention of the pilgrim mountaineers of India, who coined the Sanskrit name Himalaya—from hima (“snow”) and alaya (“abode”)—for that great mountain system.
• The sand dune keeps shifting because of the wind blowing over the surface and they are known as “shifting dunes”. These dunes have two slopes, one is steep and the other is mild.

A dune is a mound of sand formed by the wind, usually along the beach or in a desert. Dunes form when wind blows sand into a sheltered area behind an obstacle. Dunes grow as grains of sand accumulate.

The sand dune keeps shifting because of the wind blowing over the surface and they are known as “shifting dunes”. These dunes have two slopes, one is steep and the other is mild.
