weathering | National Geographic Society

Weathering describes the breaking down or dissolving of rock s and mineral s on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away.

5 Chemical Weathering Examples and How They Occur

Chemical Weathering Facts. When it comes to chemical weathering, it's all about chemistry. By looking at the term "chemical weathering," you can see that a chemical reaction causes something to break down or "weather." That "something" is rocks and minerals.. In chemical weathering, rocks and minerals are reacting to acids, oxygen, carbon and water.

Weathering Module Introduction

Physical Weathering (some material on this page borrowed from USGS) Physical Weathering. The two main types of weathering are physical and chemical weathering. This page describes mechanical (physical) weathering (and more). Rocks are naturally fractured at several levels. Mineral grains have boundaries, which can be areas of weakness in the rock.

Weathering i s the break-up and decomposition of rocks in-situ (in their place of origin). Weathering does not involve the movement of material and this makes it different to erosion. Weathering can be broken into either three categories: Chemical Weathering: The break down of rocks caused by a change in their chemical make-up.
