Depositional Landforms by Rivers

Q. Choose the factors that influence the type of landforms created by rivers.

1. Volume of flowing water
2. Speed of the river
3. Source of the river
4. Volume of sediments in the river

Q. How are alluvial fans created by rivers?

1. Erosion of landforms in the middle course of the river
2. Deposition of heavier sediments due to gentler slopes
3. Erosion of outer banks of a river to form a loop
4. Collapsing of hard rocks due to the pressure of a waterfall

Q. When a river floods, the finer particles are deposited away from the banks whereas the coarse particles are deposited near the banks. This results in the formation of which type of landform?

1. Floodplains
2. Alluvial Fans
3. Levees
4. Deltas
