Quizplus · Accepted Answer

Soil material is mostly made up of small bits of rocks, such as sand, silt, and clay. Silica is a common mineral found in these rocks and therefore is a major component of soil. Humus is the organic material that soil contains, which is made up of decomposed plant and animal matter. Loam is a type of soil that contains a mixture of sand, silt, and clay along with organic matter, but not all soil is loam. Hydrogen and air can be present in soil, but they are not major components.
