Weathering of rocks is the process by which rocks are broken down physically or chemically by natural events in the environment.
The different aspects of the environment can cause weathering and are referred to as weathering agents. These weathering agents include; Water, animals,changes in temperature, ice, acids, plants, salt and rainfall.
Physical weathering - this is the process by which rock material are broken down mechanical means such as when rolling down a hill or along river beds.
Chemical weathering - involves the breakdown of rocks by the reaction of the rock minerals by reaction with chemicals such as acids.
Factors that affect the rate of weathering:
1) Parent rock
2) Soil
3) Length of exposure to weathering agents
4) Climate
Climate:
- The climate of a region affects the weathering of rocks because rocks weather faster when exposed to higher rainfall amounts and temperature. These factors increase the rate at which weathering occurs.
- This therefore means that rocks in the tropical region would weather at a faster rate that rocks in the temperate regions due to higher temperatures and rainfall in the tropic regions than temperate regions.
