What is deposition?

Back

Deposition is the process by which eroded materials are dropped or settled in a new location.

Front

What factors influence soil formation?

Back

Factors influencing soil formation include climate, parent material, topography, organisms, and time.

Front

What is soil texture?

Back

Soil texture refers to the relative proportions of different particle sizes in the soil, such as sand, silt, and clay.

Front

How does climate affect soil formation?

Back

Climate affects soil formation by influencing the rate of weathering and organic matter decomposition; for example, hot, wet climates promote faster weathering.

Front

What role do microorganisms play in soil formation?

Back

Microorganisms contribute to soil formation by breaking down organic matter, which adds nutrients and improves soil structure.

Front

What is soil permeability?

Back

Soil permeability is the ability of soil to transmit water and air through its pores.
