River Valley and Channel Formation

River valley and channel formation involves various types of erosion, excluding weathering.
The main factor contributing to the formation of V-shaped valleys in the upper course of a river is vertical erosion.

Middle and Lower Course of a River

Wider and deeper valleys are formed in the middle course of a river, along with the development of meanders.
Broad floodplains and levees are formed in the lower course of a river due to the deposition of sediment.

Upland Landforms

A pedestal rock is not an upland landform formed by vertical erosion.

River Processes

Eroded materials are carried downstream by a river through the process of transportation.
Deposition occurs in river processes when the river's velocity decreases, causing sediment to settle.

Meanders and Oxbow Lakes

The process that leads to the formation of oxbow lakes is cutoff.
Cliff formation on the outer banks of meanders is primarily caused by erosion.

Floodplains and Levees

The formation of floodplains is determined by the amount of sediment deposited during floods.
Levees are primarily constructed to prevent flooding by containing the river's flow.

Waterfalls and Landforms

Hard, resistant rock is typically found at the base of waterfalls.
A meander belt is a type of landform formed by alternating erosion and deposition in a river.

Sediment Deposition

Sediments spread out and deposit on adjacent land during floods due to a decrease in the river's velocity.
Slip-off slopes on the inner banks of meanders are formed primarily due to erosion.
