What is weathering?

The process by which rocks, soils, and minerals are broken down into smaller pieces or altered in their composition, often by exposure to the atmosphere and living organisms.

What are the two main types of weathering?

Physical weathering and chemical weathering.

What is physical weathering?

The process of breaking down rocks into smaller pieces without changing their chemical composition.

What is chemical weathering?

The process of breaking down rocks through chemical reactions that change their composition.

Impact of human activities on weathering

1. Mining and quarrying

2.Pollution that causes acid rain-varipus places that lead to unhealthy air and polluted it

Mechanical weathering

The process where rocks are broken down into smaller pieces without changing their chemical composition
