Is mechanical weathering a chemical or physical process?

In this lab, you observed how different factors such as velocity, gradient, and volume , or amount of water in a stream, affect the rate of erosion, the transport of materials from one area to another by water.

Explanation:

Flowing water has a strong influence on erosion and the carrying of soil sediments, especially in bare and sloping soils. This type of erosion is called fluvial erosion and it occurs with the influence of several factors such as speed, gradient and volume or amount of water in a stream.

This type of erosion reinforces the need for vegetation cover in the soil. This is because the vegetation cover will allow water to infiltrate the soil more easily.
