- Fjords are formed by aeolian activities
- Oxbow lakes are formed in fluvial environments
- Ventifacts are formed by glaciers
Hide Solution
Verified By Collegedunia
The Correct Option is A, C
Solution and Explanation
Step 1: Analyze each statement.
- (A) Karst topography is formed in limestone terrains:
Karst landscapes are produced by the dissolution of soluble rocks like limestone, dolomite, and gypsum. They are characterized by caves, sinkholes, and underground drainage.
$\Rightarrow$ This statement is Correct. - (B) Fjords are formed by aeolian activities:
Fjords are long, deep, narrow inlets of the sea created by glacial erosion, not by wind (aeolian) processes.
$\Rightarrow$ This statement is Incorrect. - (C) Oxbow lakes are formed in fluvial environments:
Oxbow lakes are crescent-shaped lakes formed when a river meander is cut off from the main channel due to river processes (fluvial).
$\Rightarrow$ This statement is Correct. - (D) Ventifacts are formed by glaciers:
Ventifacts are rocks shaped, polished, or faceted by wind-driven sand (aeolian activity), not by glaciers.
$\Rightarrow$ This statement is Incorrect. Step 2: Final Answer.
The correct statements are: \[ \boxed{\text{(A) and (C)}} \]
