Question

Which of the following erosional landforms are associated with Aeolian processes? \[ \begin{aligned} A.&\ \text{Zeugen} B.&\ \text{Pingo} C.&\ \text{Inselberg} D.&\ \text{Yardangs} \end{aligned} \] Choose the correct answer from the options given below:

• A. A, B and C only
• B. B, C and D only
• C. A, C and D only
• D. A, B and D only

Hint:

Aeolian erosional landforms: \[ \boxed{ \begin{aligned} \text{Zeugen} &\rightarrow \text{Wind Erosion}, \text{Yardangs} &\rightarrow \text{Wind Erosion}, \text{Inselberg} &\rightarrow \text{Arid Landscape}, \text{Pingo} &\rightarrow \text{Periglacial Region}. \end{aligned} } \] Mnemonic: “ZYI = Zeugen, Yardang, Inselberg; Pingo = Polar.”

Answer 1

The Correct Option is C

Concept: Aeolian (wind) erosion produces characteristic landforms such as zeugen and yardangs. Inselbergs are also commonly associated with arid environments where wind erosion and weathering expose resistant rock masses. A pingo is a periglacial landform formed by the freezing of groundwater and is not related to aeolian processes.

Step 1: Evaluate each landform. \[ \begin{aligned} A.&\ \text{Zeugen} \rightarrow \text{Aeolian erosional landform (True).} B.&\ \text{Pingo} \rightarrow \text{Periglacial landform (False).} C.&\ \text{Inselberg} \rightarrow \text{Associated with arid/aeolian landscapes (True).} D.&\ \text{Yardangs} \rightarrow \text{Aeolian erosional landform (True).} \end{aligned} \]

Step 2: Identify the correct combination. \[ \boxed{ A,\ C,\ \text{and}\ D } \] Hence, \[ \boxed{\text{(C)}} \]
