Which of the following is an erosional landform created primarily by river action?

Correct option is C

The correct answer is: (c) Gorge
Explanation:
· A gorge is a deep, narrow valley with steep sides formed mainly due to the down-cutting action of rivers.
· It is an erosional landform that develops when rivers cut rapidly into their beds, often in regions of resistant rocks or during youthful stages of a river.
· Examples: Indus Gorge, Grand Canyon (USA).
Information Booster:
· River landforms are classified into erosional, depositional, and erosional-cum-depositional.
· Youthful stage → Erosional features like gorges, waterfalls, rapids.
· Mature stage → Meanders, oxbow lakes.
· Old stage → Depositional features like floodplains, deltas.
· Gorges are usually associated with vertical erosion.
Additional Knowledge:
· Moraine → Glacial depositional landform made of debris deposited by glaciers.
· Delta → Depositional landform at the river mouth formed by sediment deposition.
· Levee → Natural embankment formed alongside riverbanks due to repeated floods and sediment deposition.
