Examples of Erosional Landforms; Landform Description Image Deflation basin: A depression in the land that can be found in deserts due to the removal of particles by wind; it can also be referred to as a "blowout". Blowout outside of Earth, Texas: Ventifacts: Rock samples that demonstrate the erosion caused by aeolian processes over time.
Peneplain – Low-relief plain formed by protracted erosion; Peninsula – Landform surrounded more than half but not entirely by water; Pingo – Mound of earth-covered ice; Pit crater – Depression formed by a sinking or collapse of the surface lying above a void or empty chamber; Plain – Expanse of land that is mostly flat and treeless
Facing the wind is a steep, blunt face that gradually gets lower and narrower toward the lee end. [2] Yardangs are formed by wind erosion, typically of an originally flat surface formed from areas of harder and softer material. The soft material is eroded and removed by the wind, and the harder material remains.
In troughs, the structure's topography can accelerate flows and form jets that result in maximum erosion along the deflation basin floor and laterally expand the slopes of the blowout. Additionally, when the wind flows on top of the blowout's lateral walls, sediment transport is at its maximum in the middle axis of the trough depositional lobe ...
Wind erosion of soil at the foot of Chimborazo, Ecuador Rock carved by drifting sand below Fortification Rock in Arizona (Photo by Timothy H. O'Sullivan, USGS, 1871). Aeolian processes, also spelled eolian, [1] pertain to wind activity in the study of geology and weather and specifically to the wind's ability to shape the surface of the Earth (or other planets).
A stack or sea stack is a geological landform consisting of a steep and often vertical column or columns of rock in the sea near a coast, formed by wave erosion. [1] Stacks are formed over time by wind and water, processes of coastal geomorphology. [2] They are formed when part of a headland is eroded by hydraulic action, which is the force of ...
The rocks are deformed in a number of different ways: by erosion and weathering, glacial action, or from a sudden disturbance. Mushroom rocks are related to, but different from, yardang. [1] A mushroom rock, rock pedestal, or gour is a typical mushroom-shaped landform that is formed by the action of wind erosion. At an average height of two to ...
Erosion-related: Blowout: a depression created by wind erosion typically in either a partially vegetated sand dune ecosystem or dry soils (such as a post-glacial loess environment). [1] Glacial valley: a depression carved by erosion by a glacier. River valley: a depression carved by fluvial erosion by a river.
