Weathering: Types and Processes

Weathering is the process by which rocks and minerals on the Earth's surface break down or dissolve over time. There are two main types of weathering: physical and chemical. Physical weathering, also known as mechanical weathering, occurs when rocks are broken down through mechanical processes such as wind, water, gravity, freeze-thaw cycles, or the growth of roots into rock. Chemical weathering, on the other hand, occurs when reactions between rock and another substance dissolve the rock, causing parts of it to fall away. Biological weathering, which is a part of both physical and chemical weathering, is caused by the movements of plants and animals, such as burrowing rabbit or plant roots that widen cracks in rocks.

Physical weathering, or mechanical weathering, is the process by which rocks are broken down through mechanical processes. Water is a key agent in physical weathering, as it can cause rocks to crumble through erosion. For example, waves

Explore the process of weathering, where rocks and minerals on Earth's surface break down over time. Learn about physical weathering, which involves mechanical processes like wind, water, and freeze-thaw cycles, and chemical weathering, which occurs through reactions between rock and other substances. Understand the role of biological weathering, caused by movements of plants and animals, in the breakdown of rocks.
