WebErosion occurs when water transports sediment from one place to another. For example, a river can carry mud downstream. In general, water has more erosional power when it flows faster and has more volume. Deposition (also called sedimentation) occurs when water drops sediment in a new location. For example, ocean waves can deposit sand on a beach. WebScales and erosion Soil erosion – the entrainment, transport and deposition of soil particles – is an important phenomenon to understand; the quantity of soil loss …
WebThe largest processes on a physical scale occur globally, like plate tectonics, the circulation of the oceans and atmosphere, and very large impacts and eruptions. The smallest happen on a microscopic scale. These include mineral crystallization, chemical reactions within rocks, and other interactions between atoms and molecules.
