Study Notes
Weathering vs Erosion
- Weathering is the breakdown of rocks and soils in place, whereas erosion involves the removal and transport of rocks and minerals.
Agents of Weathering and Erosion
- The principal agent behind physical and chemical weathering is water.
- Biological agents, such as plant roots and microorganisms, can cause chemical weathering, also known as biochemical weathering.
Types of Weathering
- The weathering process that involves the breakdown of rocks and soils through the mechanical effects of heat, water, and ice is thermal weathering.
Erosion
- The agents involved in the transport of rocks and minerals in erosion are water, wind, ice, and gravity.
- The removal of rock or soil as clastic sediment is called denudation.
- Examples of agents of erosion include running water, glaciers, wind, and waves.
- The rate of erosion is controlled by factors such as slope, climate, and vegetation cover.
Coastal Erosion
- The process responsible for coastal erosion by the sea and waves is abrasion.
