Which three statements about soil formation are true? - the composition of soil depends largely on the composition of the parent rock. - the chemical composition and structure of soil remains constant for millennia. - soil becomes less fertile when it is mixed with decaying organic matter. - strong roots of shrubs and trees hold on to soil and protect it from erosion. - soil formed from local rock is residual soil, and soil formed from distant rock is transported soil.

The following statement about soil formation are true:
1. The composition of soil depend largely on the composition of the parent rock.
2. Strong roots of shrubs and trees hold on to soil and protect it from erosion.
3. Soil formed from local rock is residual soil and soil formed from distant rock is transported soil.
Soil are typically formed from rocks. The nature of the soil depend on the type of rock from which the soil was formed. It takes a long time for a soil to be formed from a parent rock. Erosion is the process that carries the surface soil away, but the root of shrub and trees usually prevent this by holding on to the soil particles.
