Much of the soil in the High Plains ecoregion of Texas consists of heavy clay. The material of this clay is often similar to the materials in the nearby rocks. What is the relationship between the rocks and the soil?
A- Weathering breaks off small pieces of rock that become part of the soil.
B- Deposition uses the small particles in the soil to create rocks.
C- Precipitation causes soil to stick together and form rocks.
D- Erosion takes away parts of the rocks that are not useful to the soil.
