How does the inorganic portion of soil form?
a. soil get formed by melting cooling process
b. rocks get weathered by chemical and physical means to form soils
c. heat and pressure change rocks into soils
d. sand and silt get deposited by rivers and streams

Option (B)

Explanation:

Soil refers to the thin layer that covers the upper part of the earth's surface. They are usually formed by the disintegration of rocks which contains essential minerals and nutrients that support the growth of plants and trees. This broken and eroded materials are carried by streams, wind, and rivers to the site where there occurs proper and abundant vegetations. Soil also contains organic materials and water along with these minerals.

Soil is formed depending upon the factors such as vegetation cover, amount of precipitation, type of rocks present and also the time required for their formation. They are generally formed by the combination of sand, clay, and silt.

There are various layers of soil namely O, A, E, B, and C.

Thus, both the physical and chemical factors are responsible for the formation of soil.

Hence, the correct answer is option (B).
