What is weathering?

Weathering is the process through which rocks and minerals are broken down into smaller pieces over time. This natural phenomenon occurs as a result of exposure to various environmental changes and weather conditions.

Types of Weathering

There are three main types of weathering: physical weathering, chemical weathering, and biological weathering.

Physical Weathering

This type of weathering involves the breakdown of rocks and minerals into smaller pieces without changing their chemical composition. Physical weathering is mainly caused by factors such as temperature changes, wind erosion, and frost action.

Chemical Weathering

Chemical weathering occurs when rocks and minerals are broken down through chemical reactions. This process is often influenced by factors like rainfall and exposure to acidic substances.

Biological Weathering

Biological weathering is caused by the activities of living organisms, such as plants and animals, which contribute to the breakdown of rocks and minerals.

Impact of Weathering

Weathering plays a crucial role in shaping the Earth's surface and contributing to processes like erosion and land degradation. By breaking down rocks and minerals, weathering helps to recycle essential nutrients and minerals in the environment.
