Chemical Weathering is the breakdown of rock mechanisms.
When temperatures heat up, the rocks expand . As the temperatures cool down, rocks contract slightly.
Mechanical weathering is the erosion or breakdown of rock into smaller fragments by natural physical agents with no chemicals involved.
The most important mechanisms are carbonation,hydration, hydrolysis, oxidation, and ion exchange in solution.
Mechanical Weathering is effected by temperature changes.
Chemical weathering very common in locations where there is a lot of water. Water is important to many of the chemical reactions that can take place.
