Mechanical weathering is the process of breaking big rocks into little ones. This process usually happens near the surface of the planet. Temperature also affects the land. The cool nights and hot days always cause things to expand and contract. That movement can cause rocks to crack and break apart. |

Abrasion |

|
|
Chemical weathering |
Definition of chemical weathering: the erosion or disintegration of rocks, building materials, etc., caused by chemical reactions (chiefly with water and substances dissolved in it) rather than by mechanical processes. |
|
|
Oxidation |
Definition of oxidation: the process or result of oxidizing or being oxidized. |
|
|
Hydrolysis |
Definition of hydrolysis: the chemical breakdown of a compound due to reaction with water. |
|
|
Carbonation |
Carbonation - The process usually involves carbon dioxide under high pressure. When the pressure is reduced, the carbon dioxide is released from the solution as small bubbles, which causes the solution to become effervescent, or fizzy. A common example is the dissolving of carbon dioxide in water, resulting in carbonated water. |

|
Acid precipitation |
Acid precipitation-Any form of precipitation, including rain, snow, hail, fog, or dew, that is high in acid pollutants, especially sulfuric and nitric acid. Acid precipitation has a pH of less than 5.6 (the normal acidity of unpolluted atmospheric water) and is often less than pH 5.0. Also called acid rain. |
