Types of erosion include solution, corrosion, and abrasion. Most limestone and gypsum caves are formed mainly by solution. Shelter caves and many sandstone caves are formed by abrasion.

Detachment and movement of soil or rock fragments by water, wind, ice, and gravity.

The wearing away of any part of the Earth’s surface by natural agencies;

The gradual wearing away of land by action of wind or water.

A process in which rocks are worn away by mechanical action (associated with water, wind, ice or gravity).

The wearing away of land surface by wind or water, intensified by land-clearing practices related to farming, residential or industrial development, road building, or logging.

The term given to describe the action of weathering followed by the transportation of the eroded materials by wind, water, gravity or ice.

the process of wearing away, as when erosion of land is caused by water flowing over it

All processes by which earthy matter or rock is loosened and moved from place to place. It includes processes of weathering, solution, corrosion, and transportation.

The wearing away of surface matter, usually by wind and water.

To eat into or wear away gradually

The process in which a material is worn away by a stream of liquid (water) or air, often due to the presence of abrasive particles in the stream.

The gradual wearing away of land by water, wind and general weather conditions; the diminishing of property by the elements.

The action or process of eroding: wearing away by the action of water, wind, glacial ice, etc.

The wearing away and transport of soil from land areas by wind or running water.

The wearing away of the bore of a firearm due to friction from the projectile, the action of hot powder gases, or the abrasive effects of partially burned powder grains.

The wearing away of land by the action of water, wind or glacial ice.

the removal and movement of particles of the land surface by wind, water, ice, or earth movements such as landsliding.

Gradual enlargement of a firearm's bore through the action of hot powder gasses. The process is quite distinct from abrasion and corrosion.

The process in which water or wind moves soil from one location to another. The four types of erosion are (1) sheet and rill-a general washing away of a thin uniform sheet of soil usually caused by rainfall or irrigation runoff (2) gully-channels or incision cut by concentrated water runoff from heavy rains (3) ephemeral-a water-worn, short-lived or seasonal incision, wider, deeper and longer than a rill, but shallower and smaller than a gully; and (4) wind-the carrying away of dust and sediment by wind in areas of high prevailing winds or low annual rainfall.

The erosion (sometimes called erodibility) index is created by dividing potential erosion (from all sources except gully erosion) by the T value, which is the rate of soil erosion above which long term productivity may be adversely affected. The erodibility index is used in the conservation compliance and Conservation Reserve Programs. For example, one of the eligibility requirements for the CRP is that land have an EI greater than 8.

The wearing away of land surface, such as soil or rock, by wind or water.

The carrying away of beach material (sand) by wave action, tidal currents, littoral drift or wind action.

the process of wearing away rocks and soil, causes particles to break up and move from one place to another.

The group of related processes by which rock is broken down physically and chemically and the products removed from any part of the Earth's surface. It includes the processes of weathering, solution, corrosion, and transportation.

The process in which material is worn away by a stream of air or liquid, often due to the presence of abrasive particles in the stream; a physical or mechanical wearing process rather than a chemical or electrochemical wearing away process.

Loss of tooth structure due to chemical rather than bacterial action.

Natural processes that wear or grind away the surface of an object. On Earth, the major agents of erosion are water and wind.

The movement of soil and rock as the result of forces produced bywater, wind, glaciers, gravity, and other influences. In most cases, a fluid medium, such as air or water, is involved.

Wearing away land through processes of nature, for example by streams and wind.

The gradual wearing away of Earth surfaces through the action of wind and water.

a gradual wearing away by the action of glaciers, running water, waves, or wind.

The wearing away of the inner surface of a gun barrel as a result of mechanical wear and the chemical action of powder gases.

The movement of soil or rock from one area to another by the action of the sea, running water, moving ice, precipitation, or wind.

a loss of the epidermis which heals without scarring

a loss of epidermis above the basal layer leaving a denuded surface.

moist, slightly depressed area of skin where the top layer (epidermis) has been removed

the act of rubbing or being rubbed away gradually.

The word 'erosion' is used in the text to represent the gradual degradation of earthen monuments. It is caused either by human activity, or more often by animals.

Erosion occurring more rapidly than geologic erosion, mainly as a result of the activities of man or other animals or of a catastrophe in nature, for example, fire that exposes the surface.

Loss of a surface area by inflammation or trauma; does not involve deeper tissues.

The progressive removal of a machine surface by cavitation or by particle impingement at high velocities.

The continuous depletion of a material due to mechanical interaction with a liquid, a mulitcomponent fluid, or solid particles carried with the fluid.

Erosion is caused by loss of the surface of a skin lesion; it is a shallow moist or crusted lesion.

Erosion is the loss of tooth structure due to chemical dissolution by acids not of bacterial origin. Erosion is found initially in the enamel and, if unchecked, may proceed to the underlying dentin.
