1. Cirque
2. Moraines
3. Eskers
Select the correct answer using the codes given below:

[A] 1 only

[B] 1 and 2 only

[C] 2 and 3 only

[D] 1, 2 and 3

Answer: D
Notes:

Cirques are the most common of landforms (erosional) in glaciated mountains. The cirques quite often are found at the heads of glacial valleys. 

  • The accumulated ice cuts these cirques while moving down the mountain tops.  
  • They are deep, long and wide troughs or basins with very steep concave to vertically dropping high walls at its head as well as sides.  
  • A lake of water can be seen quite often within the cirques after the glacier disappears. Such lakes are called cirque or tarn lakes.  
  • There can be two or more cirques one leading into another down below in a stepped sequence. 
  • When the glaciers retreated leaving behind their freight of crushed rock and sand (glacial drift), they created characteristic depositional landforms.  
  • Examples include glacial moraines, eskers, and kames. Drumlins and ribbed moraines are also landforms left behind by retreating glaciers.
