Question

place each land feature in the correct category based on the process that causes its formation.
erosion by rivers
deposition by rivers
oxbow lake
alluvial fan
delta
meander
waterfall
flood plain

Explanation:

To solve this, we analyze each landform based on river erosion (wearing away) and deposition (dropping sediment) processes:

• Erosion by Rivers (process: river wears down land):
• Meander: Formed by lateral erosion (river curves, eroding outer bank).
• Waterfall: Formed by vertical erosion (river erodes softer rock, creating a drop).
• Oxbow Lake: Forms when a meander is cut off, due to erosion of the neck of the meander.

• Deposition by Rivers (process: river drops sediment):
• Alluvial Fan: Forms when a river slows at a mountain - plain junction, depositing sediment.
• Delta: Forms at a river’s mouth, depositing sediment into a body of water.
• Flood Plain: Forms when a river overflows, depositing sediment on the surrounding flat land.

Answer:

• Erosion by Rivers: meander, waterfall, oxbow lake
• Deposition by Rivers: alluvial fan, delta, flood plain
