What is the name for a bowl-shaped hollow structure carved by glacier in the mountain?

  1. Arete
  2. Cirques
  3. Horn
  4. Moraine


Also called armchair shaped valley.

The correct answer is: Cirques

    The correct option is b) Cirques.
    • Glacial cirques, locally known as collies, are a feature of extensive erosion common to many mountainous regions.
    • Classical curls take the form of armchair-shaped troughs with steep head walls (often culminating in sharp crests or ridges) and gentle slopes or sharply depressed valley floors.
    • In active glacial landforms, the cirque is an important catchment area for snow cover.
    • They may host small Karl glaciers trapped in bedrock cavities or serve as headwaters for larger valley glaciers.
