More from Merriam-Webster on abrasion. Why is abrasion important?
Abrasion is another form of physical weathering that causes rock to deteriorate over time. Abrasion is the reason that rocks on a riverbed are typically smooth and rounded. As water in the stream flows, it causes rocks to collide with one another, wearing off any rough edges. Wind can also aid in abrasion.
2018. Albertin, E. In the mining industry, abrasion is the most significant wear mechanism. The resistance to abrasion is a property that must be combined with other material properties, such as toughness and corrosion resistance. In the crushing, grinding and material handling operations, the most relevant wear resistant materials are steels ...
the terminology of particle wear by defining the terms "abrasion," "impact," and "grinding." "Abrasion" is defined as the mere rub-bing of pebble against pebble; "impact" is the effect of definite blows of relatively large pebbles on others, relatively small; and "grinding" is the crushing of small grains by the continued contact and pressure
