Top soil refers to the top layer of soil that has a mix of vegetative matter and soil in it. The thickness of this layer varies from location to location. If you cut through sod with a spade and create a hole about 12" deep, you can see where the top soil turns into sub soil, which is a denser, lighter layer of soil.
Generally, the top soil is darker because of the amount of decomposed plant matter in it - and the subsoil is lighter because it is mostly the mineral content: silt, clay, and sand.

∙ 15y agoTopsoil is as the name indicates, the top layer of soil and is composed of both inorganic (sand, clay, and/or other granular matter) and organic matter (humus). Compost is composed of strictly organic matter in a partially broken down state.

∙ 15y agoTopsoil is considered to be the outermost layer of soil. It is generally meant to indicate the first 2 to 8 inches of ground. Subsoil is, as the name indicates, located below the topsoil. This portion of soil may include siliclastic materials, such as clay, that has been partially eroded by the elements. Bedrock is below the subsoil, consiting of consolidated rock. The rockhead is the top of the bedrock, followed by superficial deposits, also known as drift, which can run many meters below the surface.

What is the difference between soil and wind?
Soil is the nutrient-rich top layer of the ground, suitable for growing plants. Wind is the large-scale movement of air across the planet. Among obvious differences, the primary component of wind is gas, while soil is mostly solid. Wind is a component of weather, while soil is affected by weather. And wind can be a factor in soil depletion, while soil generally plays no part in determining the wind's speed or direction.
Which 2 layers of the soil are least likely to contain humus?
the two layers are sub soil The layer of soil that has little or no humus in it is the subsoil. The top layer of the soil has the most humus in it because the dead leaves fall from the plant and go back into the soil.
What is the difference between erosion and leaching?
