ABRASION Wind can grind and wear down rocks by abrasion. Abrasionhappens when rock or sand wears down larger pieces of rock. Abrasion happens in areas where there are strong winds, loose sand, and soft rocks. The wind blows the loose sand against the rocks. The sand acts like sandpaper to erode, smooth, and polish the rocks. Process Description

Breccia is a sedimentary rock composed of broken fragments of minerals or rocks cemented together by a fine-grained matrix that can be similar to or different from the composition of the fragments. Fault breccia comes from the grinding action of two fault blocks as they slide past each other. METAMORPHIC ROCKS 1

Mechanical weathering involves five major processes that physically break rocks down into sediment or particles: abrasion, crystallization of ice, thermal fracture, hydration shattering, and exfoliation. Abrasion occurs from grinding against other rock particles. Crystallization of ice can result in force sufficient enough to fracture rock.

The term abrasion refers to the grinding away of rock by rock particles carried by water, ice, wind, or gravity. In cool climates, water expands when it freezes and acts as a wedge. This process is called ice wedging. With repeated freezing and thawing, cracks slowly expand until pieces of rock break off. Charles Barfield

Rock , or glacial , consists of fine-grained, silt-sized particles of rock, generated by mechanical grinding of bedrock by glacial erosion or by artificial grinding to a similar size. Because the material is very small, it becomes suspended in meltwater making the water appear cloudy, which is sometimes known as glacial milk.

Many collectors use a mechanical rock saw to cut, trim, or abrade rocks and fossils in the field or lab. Dangers of this activity include flying rock chips, wounds from the blade itself or broken blades, and rock dust, which is extremely dangerous to inhale.
