What is called weathering?

Weathering is a term which describes the general process by which rocks are broken down at the Earth’s surface into such things as sediments, clays, soils and substances that are dissolved in water. 2. The process of weathering typically begins when the earth’s crust is uplifted by tectonic forces.

What is weathering and the example?

Weathering is the wearing away of the surface of rock, soil, and minerals into smaller pieces. • Example of weathering: Wind and water cause small pieces of rock to break off at the side of a mountain. • Weathering can occur due to chemical and mechanical processes.

What is weathering and what are the two types of weathering?

There are two types of weathering: mechanical and chemical. Mechanical weathering is the disintegration of rock into smaller and smaller fragments. Frost action is an effective form of mechanical weathering. … Frost action causes rocks to be broken apart into angular fragments.

What is weathering in geography class 8?

Answer. Weathering refers to the breaking up and decay of exposed rocks. This breaking up and decay are caused by temperature fluctuations between too high and too low, frost action, plants, animals, and even human activity. Weathering is the major process involved in the formation of soil.
