Soil in the thin layer of material that covers Earth’s surface. How is soil related to bedrock?
A: Soil forms below the bedrock.
B: Bedrock is one of four soil components.
C: Bedrock hardens to form soul.
D: Soil forms from the weathering of bedrock.
D: Soil forms from the weathering of bedrock.
D: Soil forms from the weathering of bedrock.
The correct answer is D: Soil forms from the weathering of bedrock.
Explanation: Soil is closely related to bedrock because it is formed from the process of weathering, which breaks down the bedrock into smaller particles. Over time, water, wind, temperature changes, and other environmental factors cause the bedrock to undergo physical and chemical weathering. This process breaks down the rocks into smaller pieces, creating soil particles.
As the bedrock continues to weather, organic matter such as dead plants and animals, along with minerals and nutrients, become mixed with the rock particles. These organic materials and minerals contribute to the fertility and composition of the soil. The weathering process continues as more organic matter accumulates, eventually forming a thin layer of material on top of the bedrock, which we refer to as soil.
Therefore, the correct answer is D: Soil forms from the weathering of bedrock.
