Biological Activity
- Biological weathering is the contribution to or removal of minerals and ions from the weathering environment and physical changes due to the growth or movement of organisms.
- Burrowing and wedging by organisms like earthworms, termites, rodents etc., help in exposing the new surfaces to chemical attack and assist in the penetration of moisture and air.
- Human beings by disturbing vegetation, ploughing and cultivating soils, also help in mixing and creating new contacts between air, water and minerals in the earth’s materials.
- Decaying plant and animal matter helps in the production of humic, carbonic and other acids which enhance decay and solubility of some elements.
- Plant roots exert tremendous pressure on the earth’s materials mechanically breaking them apart.

Weathering| Class 11 Geography Notes
Weathering is the process of breaking down rocks, minerals, and other materials on the Earth’s surface. It is a natural process that is caused by a variety of factors, including wind, water, ice, temperature changes, and plants and animals. Weathering can occur in a variety of different environments, from deserts to mountains to oceans. Weathering is an important process because it helps to create soil, which is essential for plant growth. It also helps to shape the Earth’s surface by breaking down rocks and creating new landforms. Weathering can also have a negative impact on human activities, such as by causing erosion and damage to buildings and infrastructure.
