The right option is; A. windblown sand cutting and polishing exposed rock surfaces
Abrasion is best described as windblown sand cutting and polishing exposed rock surfaces.
Abrasion is a process of erosion which occurs when materials such as soil or rock is removed and wears away at a surface over time. The concentration, hardness, speed and mass of the moving particles are the factors that determine the level of abrasion. Abrasion generally can be caused in four ways which are; by wind, by ice or glaciation, through the action of waves, and by rivers. Abrasion can be found on rocky mountains, on cliffs, at beaches, streams, and beneath glaciers.
Metabolism: chemical reactions in cells
Countless chemical reactions take place in cells and are responsible for all the actions of organisms. Together, these reactions make up an organism's metabolism. The chemicals taking part in these reactions are called metabolites.
