Question

Quizplus · Accepted Answer

Soil development is influenced by various factors such as climate, organisms, parent material, topography, and time. For instance, soil formation in a wet, warm climate will proceed faster than in a cold, dry climate. Organisms such as bacteria, fungi, and earthworms are also crucial in soil formation, as they decompose organic matter and help release nutrients into the soil.

Answer: E
 Soils that are rich in mineral matter commonly have a dark color due to the presence of organic matter. The organic matter contains humus, which is composed of decomposed plant and animal material. The amount of organic matter in soil can vary, with some soils having very little organic matter and appearing lighter in color. Soils that have become depleted of nutrients may also appear lighter in color.
