Abrasion is a process of weathering that occurs when material being transported wears away at a surface over time, commonly happens in ice and glaciers...

marring, or rubbing away Abrasion (geology), mechanical scraping of a surface by friction between moving particles Abrasion coast, a coastline that is...

Abrasion is the process of scuffing, scratching, wearing down, marring, or rubbing away. It can be intentionally imposed in a controlled process using...

less resistant rock below from wind abrasion which leaves it standing isolated. As the top is further eroded by abrasion and weathering, the excess material...

Structural geology is the study of the three-dimensional distribution of rock units with respect to their deformational histories. The primary goal of...

deflation rather than abrasion, or other processes. Yardangs are one kind of desert feature that is widely attributed to wind abrasion. These are rock ridges...

In geology, a terrace is a step-like landform. A terrace consists of a flat or gently sloping geomorphic surface, called a tread, that is typically bounded...

The Rock Abrasion Tool (RAT) is a grinding and brushing installation on NASA’s twin Mars Exploration Rovers, Spirit (MER-A) and Opportunity (MER-B), which...

A cliffed coast, also called an abrasion coast, is a form of coast where the action of marine waves has formed steep cliffs that may or may not be precipitous...

striations or striae are scratches or gouges cut into bedrock by glacial abrasion. These scratches and gouges were first recognized as the result of a moving...

base, the material-carrying capacity of the wind is at its maximum, so abrasion (erosion by wind in which transported materials hit an exposed rock surface...

subsidence of the slope. On the sea coast, rock towers are created by abrasion and isolation of the more resistant parts of the worn and abraded coast...

The exposed geology of the Yosemite area includes primarily granitic rocks with some older metamorphic rock. The first rocks were laid down in Precambrian...

Roundness is the degree of smoothing due to abrasion of sedimentary particles. It is expressed as the ratio of the average radius of curvature of the edges...

glacial plucking and abrasion, and the resulting clasts of various sizes will be incorporated to the glacier's bed. Glacial abrasion is the weathering of...

Abrasion, plucking, and freeze-thaw action creates the U-shaped valley unique to glacial erosion. The intense pressure from the ice causes abrasion....

Harry's Wife was another stack which was eroded through corrosion and abrasion, until the bottom was so weak the top fell away, leaving a stump. Hydraulic...

excavations and geological data. The cave itself is around 7m deep and made of soft hyaloclastite, which is why the figures could be carved by abrasion and then...

The exposed geology of the Capitol Reef area presents a record of mostly Mesozoic-aged sedimentation in an area of North America in and around Capitol...

coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes...

often around flat-top elevations. They are the result of denudation and abrasion during the regressions of the Caspian and Aral seas. Most commonly they...

brooches, and other types of jewelry where it will not encounter impact or abrasion. Even in these uses it should be considered to be a very delicate stone...

to machine steel materials at high cutting speed. It is also used as an abrasion-resistant surface coating on metal parts, such as tool bits and watch mechanisms...

horizontal or gently inclined surface of marine origin, mostly an old abrasion platform which has been lifted out of the sphere of wave activity (sometimes...

compression. In soils, this is an irreversible process. Sediment degradation by abrasion and fracture decreases the size of particles, which tends to decrease pore...

In geology, a placer deposit or placer is an accumulation of valuable minerals formed by gravity separation from a specific source rock during sedimentary...

continues to be eroded by ice segregation and abrasion. Should ice segregation, plucking and abrasion continue, the dimensions of the cirque will increase...

build various stochastic 3D models just using a few thin sections. Ion-abrasion SEM (IA-SEM) is a method of nanoscale 3D imaging that uses a focused beam...

Provenance in geology, is the reconstruction of the origin of sediments. The Earth is a dynamic planet, and all rocks are subject to transition between...

from the movement of ice. Glaciers erode by multiple processes including: Abrasion/Scouring – debris in the basal ice scrapes along the bed, polishing and...
