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.
Atoms, molecules, cell membranes, then cell (in order from smallest to biggest).

Answer:
invasive species are a problem both in anthropogenically altered and natural environments
Explanation:
An invasive species can be defined as a non-native species introduced into a new environment which then becomes abundant. Only in the US, it is believed that there are approximately 4,000 invasive species (some examples include the feral pigs, grey squirrels, European rabbits, etc.). In general, invasive species have a negative impact on the ecosystem, especially by displacing native species and thereby altering the trophic chain. In anthropogenically altered environments (anthromes), human beings are considered to be an invasive species.
