Question

defination of soil profile

Answer 1

the horizon layer of soil is called soil profile. It is also known as soil horizon

Answer 2

From the upmost layer of soil, which we can see, till the above of the underground water table, the SOIL can be DIVIDED into FOUR LAYERS— namely,

*A-HORIZON (or) TOPSOIL(the one which we see generally,along with a layer of humus on top),

under it lies

*B-HORIZON (or) SUBSOIL(which we can see in barren or eroded lands),

under it lies the

*C-HORIZON (or) REGOLITH(a layer of semipermeable rocks),

and at last, comes the

*BEDROCKS(a layer of impermeable rocks, that continues till the underground water table).

These FOUR LAYERS, together are known as the SOIL HORIZON (or) SOIL PROFILE.
