Solution
Explanation:
The different layers of soil are:
1) A-Horizon: This is the uppermost layer of the soil and is called as topsoil. The colour of this layer is the darkest since it is rich in humus and minerals. It is soft, and porous and holds more water than the other layers. Plants get most of the nutrients and water from this layer.
2) B-Horizon: It is the second most layer from the top, lighter in color, may contain little humus and is rich in minerals. It serves as a water reservoir.
3) C-Horizon: It consists of small pieces of original rock broken due to weathering.
4) Bedrock: It is the bottom layer of the soil and is unweathered solid rock.
