Which of the following are problems related to soil?

A) individual grains lose contact with one another as water squeezes between them
B) certain clay minerals increase in volume when they become wet
C) soils that do not compact uniformly because of varying amounts of clay
D) erosion due to loss of plant cover, such as from overgrazing
E) all of these

Clay Minerals

A group of hydrated silicates of aluminum, sometimes with iron, magnesium, or other cations, which possess fine-grained structures and are a major component of soils.

Plant Cover

The layer of vegetation or plants that covers the ground in a specific area, crucial for maintaining ecosystems and influencing water and soil quality.

Erosion

Erosion is the process by which natural forces like water, wind, ice, and gravity wear away rocks and soil, transporting them from one place to another.
