Abrasion is mechanical scraping of a rock surface by friction between rocks and moving particles during their transport in wind, glacier, waves, gravity or running water, after friction, the moving particles dislodge loose and weak debris from the side of the rock, these particles can be dissolved in the water source. Friction is the Force resisting the relative motion of two Surfaces in contact or a surface in contact with a fluid (e Wind is the flow of Air or other Gases that compose an Atmosphere (including but not limited to the Earth's) "Glacial" and "Glaciation" redirect here For the geological periods see Glacial period. A wave is a disturbance that propagates through Space and Time, usually with transference of Energy. Gravitation is a natural Phenomenon by which objects with Mass attract one another Water is a common Chemical substance that is essential for the survival of all known forms of Life.
The intensity of abrasion depends on the hardness, concentration, velocity and mass of moving particles. Hardness refers to various properties of Matter in the Solid phase that give it high resistance to various kinds of shape change when Force In Chemistry, concentration is the measure of how much of a given substance there is mixed with another substance In Physics, velocity is defined as the rate of change of Position. Mass is a fundamental concept in Physics, roughly corresponding to the Intuitive idea of how much Matter there is in an object
Abrasion by a glacier
A glacier can "carve" a valley, cirque, or a tarn (glacial lake), by wearing away rocks and soil through abrasion and plucking up and moving large pieces of rock and debris. "Glacial" and "Glaciation" redirect here For the geological periods see Glacial period. A cirque ( French for " Circus " is an Amphitheatre -like Valley, or valley head formed at the head of a Glacier by Plucking, in the sense relating to Glaciers is when a glacier erodes away chunks of Bedrock to be later deposited as Glacial erratics Glacial plucking

Erosion is the carrying away or displacement of solids ( Sediment, Soil, rock and other particles usually by the agents of currents such as wind Glacial striations or glacial grooves are scratches or gouges cut into Bedrock by process of glacial abrasion. Sedimentary rock is one of the three main rock types (the others being igneous and Metamorphic rock)Dapyx Software network: MP3 Explorer | Ebook Manager | Zenithic
