Erosion of mountains massifs can create a pattern of equally high summits called summit accordance. [73] It has been argued that extension during post-orogenic collapse is a more effective mechanism of lowering the height of orogenic mountains than erosion. [74] Examples of heavily eroded mountain ranges include the Timanides of
Splash erosion is generally seen as the first and least severe stage in the soil erosion process, which is followed by sheet erosion, then rill erosion and finally gully erosion (the most severe of the four). [6] [7] In splash erosion, the impact of a falling raindrop creates a small crater in the soil, [8] ejecting soil particles. [9]
Flute – in geology, process of differential weathering and erosion that produces a corrugated surface of ridges or flutes; Honeycomb weathering – Form of cavernous weathering and subcategory of tafoni; Inselberg – Isolated, steep rock hill on relatively flat terrain
For example, blending a polymer with another polymer that is very reactive to water will speed up the degradation process and cause surface erosion. On the other hand, decreasing the dimensions of a material will allow water to travel to the center of the material more quickly, which speeds up the diffusion process and causes bulk erosion.
The Universal Soil Loss Equation (USLE) is a widely used mathematical model that describes soil erosion processes. [1]Erosion models play critical roles in soil and water resource conservation and nonpoint source pollution assessments, including: sediment load assessment and inventory, conservation planning and design for sediment control, and for the advancement of scientific understanding.
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 example of erosion surface is road surface erosion which is caused by natural and anthropogenic factors.
This can lead to erosion, waterlogging, lateritization or podzolization (according to climate and topography). [83] Tillage mixes the different soil layers, restarting the soil formation process as less weathered material is mixed with the more developed upper layers, resulting in net increased rate of mineral weathering. [84]
Attrition is the process of erosion that occurs during rock collision and transportation. The transportation of sediment chips and smooths the surfaces of bedrock; this can be through water or wind. [1] Rocks undergoing attrition erosion are often found on or near the bed of a stream. [2]
