Question

The study of the vertical section of soil is known as-
A. soil study
B. Soil profile
C. Soil layering
D. Soil weathering

Answer 1

Hint: Study of the vertical section consists of multiple horizontal layers of soil called horizons. Horizons' layers are parallel to each other. Each Soil horizon or soil layers are different from each other with respect to their age, texture, colour, etc, these horizons can be observed when the soil layers are dug through vertically.

Complete answer:

Option – A – SOIL STUDY
The term soil study refers to the depth study of soil in all its forms. The study is divided into two branches the first branch is known as Pedology meaning the study of soils in their natural form and environment. The other branch of soil study is Edaphology studies the ways soil affects plants, fungi, and other living things.

Option – B – SOIL PROFILE
The term soil profile is used for vertical sections of soil. It allows you to examine the structure of the soil. A soil profile is divided into layers called horizons. The main soil horizons are A, B, C, and D.
A & B HORIZON- Most important for plant growth, the A and B horizons are the top two layers of the soil. The A horizon is called topsoil. The B horizon is called subsoil.
C HORIZON- the C Horizon consists of weathering rock.
D HORIZON - The D horizon is bedrock.

Option – C – SOIL LAYERING
Soil layering is a different layer of the layer. The different horizons in the soil profile are regarded as soil layers that are parallel to each other. Observation of soil layers or horizons together is known as the soil profile

Option – D – SOIL WEATHERING
The term weathering is used to refer to the breaking down of rocks, soils as well as minerals and woods. Weathering of soil consists of 4 stages they are –
weathering
soil erosion
transport of soil and
Deposition of soil.

So, the correct answer is, option B- 'Soil profile'

Note: Soil layers are complex mixtures of minerals, water, air, organic matter, and countless organisms that are the decaying remains of once-living things. The soil layers form at the surface of the land and are often considered “skin of the earth.” Soil is capable of supporting plant life and is vital to life on earth.
