Question

Explain the soil profile and the different layers in it.​

Answer 1

Answer:

The soil is found in layers, which are arranged during the formation of soil. These layers called horizons, the sequence of layers is the soil profile. The layers of soil can easily be observed by their color and size of particles. The main layers of the soil are topsoil, subsoil and the parent rock.

Answer 2

Soil is made up of organic matter, minerals, gases, liquids, and organisms, all of which work together to support life.

Explanation:

Soil is found in layers that occur during the creation of the soil. The sequence of layers is known as the soil profile, and these layers are referred to as horizons.

• The color and particle size of the soil layers may clearly be distinguished. The topsoil, subsoil, and parent rock are the three primary layers of soil.
• Topsoil: This layer is made up of biological stuff and degraded substances. The hummus softens and porousizes the topsoil, allowing it to contain enough air and water. The seeds germinate and the roots of the plants grow in this layer. This layer of soil contains many living organisms such as earthworms, millipedes, and centipedes, as well as bacteria and fungi.
• Subsoil: It is a lot tougher and more compact than topsoil. Because there is less humus in this layer, it is lighter in color than the topsoil. This layer is less organic, but it is abundant in minerals that have been carried down from the topsoil.
• Parent rock soil: Parent rock, often known as bedrock, is found immediately beneath the subsoil. It is particularly hard since it contains no organic matter and is made mainly of stones and rocks.
