Q. Consider the following:

1. Cirques, moraines, and eskers are all depositional landforms.
2. Cirques are typically found at the heads of glacial valleys.
3. Moraines are long ridges composed of deposits of glacial till.
4. Eskers are ridges made of sands and gravels, deposited by glacial meltwater flowing within and beneath glaciers.

Which of the above statements is/are correct?
Answer: Only 2, 3 and 4
Notes: Statement 1 is incorrect as cirques are primarily erosional rather than depositional landforms. Statements 2, 3, and 4 are correct: cirques occur at glacial valley heads, moraines are ridges of glacial till, and eskers are sinuous ridges of sand and gravel deposited by glacial meltwater, typically under or within the ice.
