Question

Which one of the following is an erosional landform of running water?

• A. V-shaped, valley
• B. Alluvial plain
• C. Delta
• D. Sand dunes

Answer 1

Answer:

A. V-shaped, valley

V-shaped valley

• In the initial stages of a river's course (the youthful stage), the water flows rapidly down steep gradients. This high energy causes the river to cut vertically into the riverbed, a process known as vertical erosion. Over time, this deepens the channel while weathering and mass wasting pull the sides of the valley down, creating a distinct 'V' shape.

• Landforms are generally categorized into Erosional (created by wearing away rock) and Depositional (created by piling up sediment).

Landform	Agent	Type	Description
V-shaped Valley	Running Water	Erosional	Deep, narrow valleys formed in mountainous regions.
Alluvial Plain	Running Water	Depositional	Flat landforms created by the deposition of sediment over a long period by a river.
Delta	Running Water	Depositional	A fan-shaped feature formed at the mouth of a river where it enters a sea or lake.
Sand Dunes	Wind (Aeolian)	Depositional	Mounds or ridges of sand piled up by the wind, usually in deserts or beaches.
