Question

How does the thickness of the soil increase over time?

• A. By erosion of the soil.
• B. By the deposition of weathered particles.
• C. By the breaking of bed rock.
• D. By the decaying plant and animal matter.

Answer 1

The correct option is B By the deposition of weathered particles.

Over time, more and more weathered particles accumulate, leading to an increase in the thickness of the soil that is formed. The slopes along a mountain have thinner deposits as erosion is more on slopes while foothills or plains will have thicker deposits.
