Weathering

Weathering describes the breaking down or dissolving of rocks and minerals on the surface of 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. No rock on Earth is hard …

Chemical Weathering

This process occurs when water comes into contact with rocks and dissolves the minerals that make up that rock into individual elements. The dissolution of calcite is a good example of this process, when water comes into contact with rocks that have abundant amounts of calcite such as limestone the calcite dissolves into the solution.

7.3: Influences on Weathering

Igneous rocks, especially intrusive igneous rocks such as granite, weather slowly because it is hard for water to penetrate them. Other types of rock, such as limestone, are easily weathered because they dissolve in weak acids.Rocks that resist weathering remain at the surface and form ridges or hills.

In particular, limestone is weathered by rainwater containing dissolved CO2, (this process is sometimes called carbonation). Hydrolysis - the breakdown of rock by acidic water to produce clay and soluble salts. Oxidation - the breakdown of rock by oxygen and water, often giving iron-rich rocks a rusty-coloured weathered surface.
