Explanation:
Soil formation is slow but a continuous process which consists of gradual breakdown of rocks through the process of weathering. Complete answer: Soil is one of the thinnest layers of material covering earth's surface and it is formed due to weathering of rocks.
Soil forms continuously, but slowly, from the gradual breakdown of rocks through weathering. Weathering can be a physical, chemical or biological process: physical weathering—breakdown of rocks from the result of a mechanical action. ... chemical weathering—breakdown of rocks through a change in their chemical makeup.

Answer:
Soil minerals form the basis of soil. They are produced from rocks (parent material) through the processes of weathering and natural erosion. Water, wind, temperature change, gravity, chemical interaction, living organisms and pressure differences all help break down parent material.
Importance of soil
As one it the most important components of the sustainability of an ecosystem, soil we said be of great importance when it comes to the growth of vegetation.
Factors Responsible for the Formation of Soil are
1. Parent Material:
Deposited by streams or derived from in-situ weathering, these soil come with many properties like the mineral composition, the color, the particle size, and the chemical elements.
2. Climate:
The rate of weathering of the parent rock is affected by varied climate. Hence it is said to be an important factor in determining soil formation.
3. Role of temperature:
Any change in temperature can cause shrinking and swelling, frost action and general weathering in soils. Hence, temparature is said to play a vital role in soil formation.
