Soil Review

Front

What is the parent material in soil formation?

Back

Parent material is the underlying geological material (bedrock or sediment) from which soil is formed.

Front

What are the main soil types based on particle size?

Back

The main soil types are clay, silt, sand, and loam.

Front

What is the composition of sandy soil?

Back

Sandy soil typically consists of 90% sand, 5% silt, and 5% clay.

Front

What is loam soil composed of?

Back

Loam soil is composed of approximately 50% sand, 30% silt, and 20% clay.

Front

How do nutrients necessary for plant growth enter the soil?

Back

Nutrients enter the soil primarily through the decay of organic matter.

Front

What role do organisms play in soil formation?

Back

Organisms contribute to soil formation by decomposing organic material and aerating the soil.

Front

What is the effect of climate on soil formation?

Back

Climate affects soil formation through temperature and precipitation, influencing weathering processes and organic matter decomposition.

Front

How does time influence soil development?

Back

Time allows for the accumulation of organic matter and the weathering of parent material, leading to more developed soil profiles.

Front

What is topography in relation to soil formation?

Back

Topography refers to the landscape's shape and features, which can affect drainage, erosion, and the distribution of soil types.

Front

What is the significance of soil texture?

Back

Soil texture affects water retention, nutrient availability, and root penetration, influencing plant growth.
