Question

Which type of soil is likely to be found in horizon E?

a. Topsoil
b. Subsoil
c. Parent material
d. Bedrock

Answer 1

Horizon E in a soil profile is considered to be the subsoil (or B horizon) layer, not the topsoil or the parent material. The subsoil is typically found beneath the topsoil and consists of fine material that has moved downward.

Step-by-step explanation:

Horizon E in a soil profile is considered to be the subsoil (or B horizon) layer, not the topsoil (A horizon) or the parent material (C horizon). The subsoil is typically found beneath the topsoil and consists of fine material that has moved downward. It is important for nutrient cycling and water retention in the soil.

For example, in Figure 31.7, horizon E is represented as the B horizon, which is darker in color and contains more inorganic material compared to the surface layers.
