Which is a wide river valley formed by erosion?
A.flood plain
B.oxbow lake
C.alluvial fan
D.tributary
please give me the correct answer...
A. Flood Plain
ofc its gonna say that in which i dont belive this is correct!
SERIOUSLY WHY WOULD U EVEN COMMENT THEN!!!
The correct answer is A. flood plain.
A flood plain is a wide, flat area of land adjacent to a river that is formed by the erosion of the river's banks and the deposition of sediment during floods. The river erodes its banks over time and the sediment it carries is deposited on the flood plain, creating a flat, fertile area. Flood plains can be several miles wide and are typically used for agriculture and development.
Oxbow lakes are formed by meandering rivers, where a loop of the river is cut off and forms a curved lake. Alluvial fans are cone-shaped deposits of sediment that form where a river or stream flows out of a narrow canyon or valley onto a flatter plain. A tributary is a smaller river or stream that flows into a larger river.
Which feature is formed when sediment erodes away from the area as a result of a river’s flow?
beach
waterfall
deltas
alluvial fan
The correct answer is A. flood plain.
To determine the correct answer, it is important to understand the definitions and formation processes of each of the given options:
1. Flood plain: A flood plain is a wide, flat area of land adjacent to a river that experiences periodic or occasional flooding. It is formed by the deposition of sediments carried by the river during flood events.
2. Oxbow lake: An oxbow lake is a U-shaped body of water that forms when a meandering river erodes through its own narrow neck, creating a cutoff from the main channel. Oxbow lakes are typically found along meandering rivers and are not formed exclusively by erosion.
3. Alluvial fan: An alluvial fan is a fan-shaped deposit of sediment formed at the base of a mountain or hill where a fast-flowing river or stream spreads out and slows down. Alluvial fans are formed by the deposition of sediment carried by the river, rather than erosion.
4. Tributary: A tributary is a smaller river or stream that flows into a larger river. Tributaries are not formed by erosion but rather join the main river network through confluence.
Based on the given options and their definitions, the wide river valley formed by erosion would be a flood plain (option A).
