Thermal stress weathering is an important mechanism in deserts, where there is a large diurnal temperature range, hot in the day and cold at night. [14] As a result, thermal stress weathering is sometimes called insolation weathering, but this is misleading. Thermal stress weathering can be caused by any large change of temperature, and not ...
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
Honeycomb weathering – Form of cavernous weathering and subcategory of tafoni; Impact crater – Circular depression in a solid astronomical body formed by the impact of a smaller object; Joint valley – Landscape originates from the erosion of joints in the bedrock, leaving out small plateaus or ridges in between. Common in Fennoscandia.
Rock formations are usually the result of weathering and erosion sculpting the existing rock. The term rock formation can also refer to specific sedimentary strata or other rock unit in stratigraphic and petrologic studies. A rock structure can be created in any rock type or combination:
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] Thermal erosion is the result of melting and weakening permafrost due to moving water. [18] It can occur both along rivers and at the coast.
Denudation incorporates the mechanical, biological, and chemical processes of erosion, weathering, and mass wasting. Denudation can involve the removal of both solid particles and dissolved material. These include sub-processes of cryofracture, insolation weathering, slaking, salt weathering, bioturbation, and anthropogenic impacts. [4]
Abrasion is a process of weathering that occurs when material being transported wears away at a surface over time, commonly occurring with ice and glaciers. The primary process of abrasion is physical weathering. Its the process of friction caused by scuffing, scratching, wearing down, marring, and rubbing away of materials.
An example of this type of mushroom rock is the one in Timna Park, Israel. Occasionally, the chemical composition of the rocks can be an important factor; if the upper part of the rock is more resistant to chemical erosion and weathering, it erodes more slowly than the base.
