Question

What are four (4) forms of erosion?

Answer 1

Please see below.

Explanation:

If you are talking about river erosion than the four main forms of river erosion are:

1. Hydraulic action - the force of the river against its banks that causes air to be trapped in cracks and crevices. The pressure weakens the banks and gradually wears it away.

2. Abrasion - rocks carried along by the river wear down the river bed and banks.

3. Attrition - rocks being carried by the river smash together and break into smaller, smoother and rounder particles.

4. Solution - soluble particles are dissolved into the river.
