- Mechanical weathering is a physical process that breaks rocks down into smaller and smaller pieces.
- Mechanical weathering processes include frost wedging, biological activity, abrasion, and unloading.
- Chemical weathering is the breakdown of rock by chemical reactions resulting in a change in rock composition.
- Chemical weathering processes include hydrolysis, oxidation, carbonation, and acid rain.
- Soil is produced from a combination of mineral and rock particles, organic matter, water, and air.
- Factors affecting soil formation include climate, topography, parent material, plants and animals, and time.
- Soils are classified by their physical and chemical properties.
