Question

Which of the following agent of erosion is associated with drumlins?

• A. Glacier
• B. Underground water
• C. Sea waves
• D. River

Hint:

Remember these glacial landforms: \[ \boxed{ \begin{aligned} \text{Drumlin} &\rightarrow \text{Glacial Deposition}, \text{Esker} &\rightarrow \text{Glacial Meltwater Deposit}, \text{Moraine} &\rightarrow \text{Glacial Till}, \text{Cirque} &\rightarrow \text{Glacial Erosion}. \end{aligned} } \] Mnemonic: “Drumlins are shaped by drifting glaciers.”

Answer 1

The Correct Option is A

Concept: Drumlins are streamlined, elongated hills composed of glacial till. They are depositional landforms formed beneath moving glaciers and indicate the direction of ice movement.

Step 1: Identify the agent responsible. Drumlins are formed by \[ \boxed{\text{Glaciers}} \]

Step 2: Eliminate the incorrect options. \[ \begin{aligned} A. &\ \text{Glacier} \rightarrow \text{Correct. Drumlins are glacial landforms.}\checkmark B. &\ \text{Underground Water} \rightarrow \text{Forms karst landforms.} C. &\ \text{Sea Waves} \rightarrow \text{Form coastal landforms.} D. &\ \text{River} \rightarrow \text{Forms fluvial landforms.} \end{aligned} \] Hence, \[ \boxed{\text{(A)}} \]
