Erosional surfaces within the stratigraphic record are known as unconformities, but not all unconformities are buried erosion surfaces. Erosion surfaces vary in scale and can be formed on a mountain range or a rock. [2] Particularly large and flat erosion surfaces receive the names of peneplain, paleoplain, planation surface or pediplain. An ...
Erosion and changes in the form of river banks may be measured by inserting metal rods into the bank and marking the position of the bank surface along the rods at different times. [23] Thermal erosion is the result of melting and weakening permafrost due to moving water. [24] It can occur both along rivers and at the coast.
Bank erosion is the wearing away of the banks of a stream or river. This is distinguished from changes on the bed of the watercourse, which is referred to as scour. Erosion and changes in the form of river banks may be measured by inserting metal rods into the bank and marking the position of the bank surface along the rods at different times. [17]
Surface runoff can cause erosion of the Earth's surface; eroded material may be deposited a considerable distance away. There are four main types of soil erosion by water: splash erosion, sheet erosion, rill erosion and gully erosion. Splash erosion is the result of mechanical collision of raindrops with the soil surface: soil particles which ...
Although the terms erosion and denudation are used interchangeably, erosion is the transport of soil and rocks from one location to another, [1] and denudation is the sum of processes, including erosion, that result in the lowering of Earth's surface. [2]
The definition of erosion is grinding and wearing away of rock surfaces through the mechanical action of other rock or sand particles. According to the IPCC, sea level rise caused by climate change will increase coastal erosion worldwide, significantly changing the coasts and low-lying coastal areas.
River valley: a depression carved by fluvial erosion by a river. Area of subsidence caused by the collapse of an underlying structure, such as sinkholes in karst terrain. Sink : an endorheic depression generally containing a persistent or intermittent (seasonal) lake , a salt flat (playa) or dry lake , or an ephemeral lake .
The lowering of a fluvial surface, such as a stream bed or floodplain, through erosional processes. dendrite A crystal that develops with a typical multi-branching tree-like form. Denudation The lowering of the earth's surface through chemical and physical weathering. deposition The geological process by which material is added to a landform or ...
