What are the four processes of river erosion?

There are four types of erosion:

• Hydraulic action – This is the sheer power of the water as it smashes against the river banks.
• Abrasion – When pebbles grind along the river bank and bed in a sand-papering effect.
• Attrition – When rocks that the river is carrying knock against each other.

What are the 4 types of erosion GCSE?

The four main types of river erosion are abrasion, attrition, hydraulic action and solution.

What are the 4 types of deposition?

Types of depositional environments

• Alluvial – type of Fluvial deposit.
• Aeolian – Processes due to wind activity.
• Fluvial – processes due to moving water, mainly streams.
• Lacustrine – processes due to moving water, mainly lakes.

What are the different types of erosion processes?

Erosion is the process that wears away the river bed and banks. Erosion also breaks up the rocks that are carried by the river. There are four types of erosion: Hydraulic action – This is the sheer…

How does erosion take place in a river?

Erosion is the process that wears away the river bed and banks. Erosion also breaks up the rocks that are carried by the river. Hydraulic action – This is the sheer power of the water as it smashes against the river banks. Air becomes trapped in the cracks of the river bank and bed, and causes the rock to break apart.

What are the three main processes that occur in a river?

There are three main types of processes that occur in a river. These are erosion, transportation and deposition. All three depend on the amount of energy there is in a river. The energy in a river causes erosion.

How is erosion related to transportation and deposition?

Erosion, transportation and deposition all occur in a river. Moving from the upper course to the lower course, the rates of erosion, transportation and deposition change. Erosion. Erosion is the process that wears away the river bed and banks.
