Chemical weathering tends to increase during the summer as temperatures rise. These processes of weathering can affect the shape of a river landscape as mass movement such as rockfalls become more likely, as it loosens material on the valley side. Some of this material can enter the river channel and be transported when discharge increases.

Frequently Asked Questions
How does weathering erosion and deposition affect rivers?
Erosion by Slow-Flowing Rivers Rivers flowing over gentle slopes erode the sides of their channels more than the bottom. Large curves, called meanders, form because of erosion and deposition by the moving water. The curves are called meanders because they slowly “wander” over the land.
How does weathering erosion and deposition affect Earth's landscape?
The material moved by erosion is sediment. Deposition occurs when the agents (wind or water) of erosion lay down sediment. Deposition changes the shape of the land. ... Water's movements (both on land and underground) cause weathering and erosion, which change the land's surface features and create underground formations.
How does river erosion affect landscapes?
Moving water, in river and streams, is one of the principal agents in eroding bedrock and sediment and in shaping landforms. Without streams or rivers, there would be few valleys, because streams and rivers form most valleys. The landscape would wear down much more slowly through geologic time.
How is deposition related to erosion and erosion?
At some point, for various reasons, water, ice, wind, or gravity will drop sediments in a new place. This process is called deposition . Deposition is considered a constructive process, because where sediments are added, the land is raised or built up. WHAT FACTORS AFFECT EROSION AND DEPOSITION BY SURFACE WATER?
What is the driving force behind Weathering, erosion and deposition?
o the water cycle or hydrologic cycle (see graphic below) is the driving force behind WED (weathering, erosion, and deposition) o But without gravity and the sun this whole process would not occur Without this process, weathering, erosion, and deposition would have a difficult time occurring on Earth.
How does lateral erosion cause a river to slope?
The lateral erosion on the outside bend causes undercutting of the river bank to form a river cliff. There is less water on the inside bend of a meander so friction causes the water to slow down, lose energy and deposit the material the river is carrying, creating a gentle slope.
