Explain how climate affects soil formation.
Climate affects soil formation by determining the rate of weathering and erosion. Warmer temperatures and increased rainfall increase the rate of weathering, contributing more mineral material for soil formation. Climate also determines the types of organisms that are in a given area. These organisms contribute to the type of soil formed.
Explain what contributes to topsoil formation and how topsoil is important to plant growth.
Topsoil has the greatest concentration of organic matter and soil life, which makes it rich in nutrients required by plant life to thrive. Areas that have a high turnover rate of organic material will have a deeper layer of topsoil.
How does organic material enter soil?
Organic material is incorporated into soil as plant and animal matter decomposes.
