Question

Incised meanders are the representative feature of ________

• A. Rejuvenation
• B. Karst erosion
• C. Aeolian erosion
• D. Coastal erosion

Hint:

Remember these geomorphic features: \[ \boxed{ \begin{aligned} \text{Rejuvenation} &\rightarrow \text{Incised Meanders}, \text{Karst} &\rightarrow \text{Caves and Sinkholes}, \text{Aeolian} &\rightarrow \text{Dunes and Yardangs}, \text{Coastal} &\rightarrow \text{Cliffs and Sea Arches}. \end{aligned} } \] Mnemonic: “Rejuvenation cuts rivers deeper.”

Answer 1

The Correct Option is A

Concept: Incised meanders are deeply entrenched river bends formed when a river with established meanders undergoes vertical downcutting due to rejuvenation caused by uplift of land or fall in base level.

Step 1: Identify the geomorphic process. Incised meanders develop due to \[ \boxed{\text{River Rejuvenation}} \]

Step 2: Eliminate the incorrect options. \[ \begin{aligned} A. &\ \text{Rejuvenation} \rightarrow \text{Correct. Produces incised meanders.}\checkmark B. &\ \text{Karst erosion} \rightarrow \text{Forms caves, sinkholes, and limestone features.} C. &\ \text{Aeolian erosion} \rightarrow \text{Produces desert landforms such as dunes and yardangs.} D. &\ \text{Coastal erosion} \rightarrow \text{Forms cliffs, arches, stacks, etc.} \end{aligned} \] Hence, \[ \boxed{\text{(A)}} \]
