Study Notes
Weathering and Soil Formation
- Water is the principal agent behind both physical and chemical weathering.
Types of Weathering
- Mechanical weathering, also known as physical weathering, involves the breakdown of rocks through mechanical effects.
Weathering vs. Erosion
- Weathering involves the breakdown of rocks in place, whereas erosion involves the transportation of rocks and sediments away from their original location.
Soil Formation
- Organic matter is the primary component in the formation of soil after rock breaks down.
Sedimentary Deposits
- Sedimentary rocks, formed from weathering products of older rock, cover a significant portion of the Earth's continents and ocean floor.
