Answer: Don't worry Sister I will answer your question
Explanation: The coverage of Earth’s surface with soil varies from place to place. Tropical forests have thin soils that are poor in nutrients, while grasslands in temperate regions have soils that are rich and well able to support crops. There are several different classes of soil depending on how the soil is formed and where it is located. An understanding of which class of soil is found in a particular location is an important foundation to obtaining successful crop yields.
Soil is as important as water as a resource. It provides nutrients and an anchor to the roots of plants and is therefore essential to their healthy growth and yield of food. It is a complex mixture of organic and mineral content which is constantly being formed by the weathering of rocks.
Soil has a layered structure, with the topsoil being around 4 in (10 cm) deep and rich in organic material. Then there is a layer between topsoil and subsoil through which dissolved or suspended matter moves. Below this is the subsoil, where humic compounds, clay, iron, and aluminum may accumulate after leaching from the upper layers. Finally there is the actual bedrock, which is the source of the soil through weathering processes. Soil is also classified according to the size of the particles it contains. A soil with a lot of clay has fine particles, while one with a lot of gravel is coarser.
That's all Thank You
