Chemically & Physically(mechanically)

Explanation:

Weathering is the wearing away of rock found at the surface of the earth. There are different ways weathering can occur and they include;

1. Mechanical weathering: This is the breakdown of rock into bits or fragments. Physical factors such as water can lead to this breakdown. When water falls into the pores and cracks of rocks, pressure can be created that will eventually result in the breakdown of these rocks.

2. Chemical weathering: This type of weathering causes a change in the physical makeup of the rock. The new form of rock created is more prone to erosion. Temperature is factor that can speed up chemical weathering.
