Responses
A. Bedrock is one of four soil components.
B. Soil forms from the weathering of bedrock.
C. Bedrock hardens to form soil.
D. Soil forms below the bedrock.
B. Soil forms from the weathering of bedrock.
The correct answer is B. Soil forms from the weathering of bedrock.
To understand how soil is related to bedrock, it is important to know what bedrock is. Bedrock refers to the solid, hard layer of rock that lies beneath the soil. It is the layer that provides the underlying structure and support to the soil above it.
Soil, on the other hand, is the top layer of material that covers the Earth's surface. It is a rich mixture of organic matter, minerals, water, and air that supports plant growth. Soil is formed through a process called weathering, which is the gradual breaking down of rocks into smaller pieces due to various natural forces such as wind, water, and temperature changes.
As these rocks break down over time, they form smaller particles and undergo chemical changes. Eventually, through the accumulation of these particles, along with the addition of organic matter and other factors, soil is created.
Therefore, the correct answer is B - Soil forms from the weathering of bedrock.
