Study Notes
Weathering
- Weathering is the process that breaks down rocks at the Earth's surface.
- It's caused by factors like water, ice, acids, salts, plants, animals, gravity, and changing temperatures.
Types of Weathering
-
Physical (Mechanical) Weathering: This type of weathering involves the breakdown of rocks by physical forces.
- Abrasion: Rocks are worn down by friction from water, wind, or ice carrying sediment.
- Freeze-Thaw: Water seeps into cracks, freezes, expands, and breaks the rock apart.
- Exfoliation: Cracks form parallel to the surface due to pressure reduction during uplift and erosion.
-
Chemical Weathering: This involves the breakdown of rocks by chemical reactions.
- Carbonation: Carbon dioxide in rainwater forms carbonic acid, which dissolves limestone.
- Acidification: Polluting gases like sulfur dioxide and nitrogen oxide form stronger acids in rainwater, leading to acid rain.
- Hydrolysis: Water reacts chemically with rocks, breaking down chemical bonds.
- Hydration: Water reacts with rocks, changing their chemical structure.
- Oxidation: Oxygen and water react with rocks, often creating a rusty-colored surface.
-
Biological Weathering: This occurs when organisms contribute to rock breakdown.
- Plant Roots: Growing roots create cracks in rocks.
- Burrowing Animals: Animals like moles and earthworms create holes and move rock fragments to the surface.
- Chemical Compounds: Some organisms produce acids that react with rocks.
