it is the correct answer

Answer 2

The correct arrangement of the soil profile is given by option A: 3-2-1-4

• There are four main layers of soil from top to bottom are as follows:

1. Topsoil
2. Subsoil
3. Parent rock
4. Bedrock

• The following are the features of different soil profile layers:

1. The topsoil, which is humus-rich, is the soil's top layer. In the question, it is referred to as number three.
2. The subsurface is made up of clay, rock fragments, minerals, and other materials that have leached down from the topsoil. In the question, it is referred to as number 2.
3. The third layer is made up of partially worn rock particles. It is referred to as the number one in the question.
4. The parent rocks that make up the soil's bottom layer haven't been weathered yet. In the question, it is referred to as number 4.

• As a result, the right soil profile order from top to bottom is 3-2-1-4.
