Question

Explain how soil is formed​

Answer 1

Soil is the thin layer of material covering the earth's surface and is formed from the weathering of rocks. ... Weathering of rocks takes place. Rock is broken down into small particles. These small particles mix with humus (organic matter) and form soil.

Answer 2

HEYA, BUDDY !!

: $\implies$ The Soil is formed when the weathering of rocks takes place, and they break down into tiny pieces that form the soil. The various methods by which soil is formed include mechanical weathering, chemical weathering and biological weathering. So, when we describe the composition of the soil, we must take into account how the soil has been formed. In mechanical weathering, the rocks are broken down by physical weathering such as wind or running water or temperature. Chemical weathering occurs when rocks are broken down by the help of chemical reactions, and this often ends up changing the chemical composition of the soil. Biological weathering takes place when organisms weaken and disintegrate rocks. For example, the roots of trees can penetrate the cracks of rocks and end up breaking the rock.

As We Know that, The soil is a very important substance for the survival of organisms. The fertile soil helps in the development and growth of plants which are not only a source of food but also the life-sustaining oxygen. Various life forms like bacteria, algae, fungi, etc. are all supported by the soil which retains the moisture of the soil and helps in the decaying of dead organisms. Life is supported by the topsoil, which helps in reproduction, nesting, breeding, etc. of a few organisms. The fertility of the soil is also increased by the presence of various organic matter that helps in the growth of plants and the various minerals and elements present in soil help the plants to carry out various processes. This is the importance of soil.

know more, The soil is used for making various things like cups, tiles, utensils, etc. The soil contents like gravel, clay and sand which are also used in the construction process of houses, roads and buildings, etc. The useful mineral medicines like iron, calcium along with other things like petroleum jelly and cosmetics are also extracted from soil. Rainwater is absorbed by the soil, and the water seeps through and is stored as groundwater. The water is evaporated, and it is released in the air, which makes the atmosphere cooler and becomes a part of the water cycle.
