How does material in soil move?

A) the upper part of soil loses material downward
B) clay minerals and other fine particles are carried downward
C) chemical ions leached from above can accumulate in the underlying zone
D) calcium carbonate can accumulate in the soil, especially in dry environments
E) all of these

Calcium Carbonate

Calcium carbonate is a chemical compound, CaCO3, found in rocks as the minerals calcite and aragonite and is the main component of shells of marine organisms, snails, and eggs.

Clay Minerals

A group of hydrous aluminium phyllosilicates, sometimes with variable amounts of iron, magnesium, alkali metals, alkaline earths, and other cations, which are found in soils and sedimentary rocks.
