Here's a breakdown:
* Weathering: The physical and chemical breakdown of rocks, soil, and minerals through contact with the Earth's atmosphere, water, and biological organisms.
* Physical Weathering: The breakdown of rocks into smaller pieces without changing their chemical composition. This can be caused by:
* Temperature changes: Freezing and thawing of water in cracks can expand the cracks and break the rock apart.
* Abrasion: Rocks rubbing against each other due to wind, water, or ice can wear them down.
* Plant roots: As plant roots grow, they can exert pressure on rocks and break them.
* Chemical Weathering: The breakdown of rocks through chemical reactions that change the composition of the minerals. This can be caused by:
* Acid rain: Acidic rain can dissolve certain minerals in rocks.
* Oxidation: Iron in rocks can react with oxygen to form rust, which weakens the rock.
* Hydrolysis: Water can react with minerals in rocks to form new, weaker minerals.
