River Processes

What are tributaries?

• bends in the river

• wide areas of water near the mouth

• where the river reaches the sea

• small streams or rivers that run into the main channel

1. The material carried by a river is usually referred to as its

• silt.
• mud.
• load.
• alluvium.

When the velocity of the river decreases, it no longer has enough energy to carry its sediment. The sediment will be dropped at the river bed/river bank. Which process is this?

• Erosion

• Deposition

• Transportation

• Saltation

• Lateral Erosion

1. The material carried by a river is usually referred to as its

• silt.
• mud.
• load.
• alluvium.

This method of erosion is when the force of water breaks the river bed and banks.

• Attrition
• Abrasion
• Corrosion
• Hydraulic Action

What is erosion?

• River deposits rocks and soils as it flows

• River carries rocks and soils as it flows

• River removes rocks and soils as it flows
