Answer:
The soil is the topmost layer of the earth’s crust mainly composed of organic minerals and rock particles that support life. A soil profile is a vertical cross-section of the soil, made of layers running parallel to the surface. These layers are known as soil horizons.
Soil profile helps in determining the role of the soil as well. It helps one to differentiate the given sample of soil from other soil samples based on factors like its colour, texture, structure, and thickness, as well as its chemical composition
Explain
they main layers of soil are top soils sub soil and parent rock
top soil ( A horizon )
subsoil b horizon
Parent rock c horizon
humus and the smallest particles of rock is the upper layer of soil known as top soil
and subsoil does not have much humus it is lighter in colour then topsoil parent rock is below the soil and parent rock
