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


Valley formed due to glacial erosion.

The correct answer is: Cirques

    The correct option is c) Cirques.
    Cirque is an armchair-like valley formed by glacial erosion. The concave part of the glacial cirque is open on the valley side, but the bowl-shaped part is generally steep. Cliff-like slopes where ice and glacial debris converge to form three or more high sides. The Curl floor is a complex convergence zone where ice flows from multiple directions and associated rock loads are combined, thus ending in a bowl shape.
