How do you classify soil types?
The United States Department of Agriculture defines twelve major soil texture classifications ( sand, loamy sand, sandy loam, loam, silt loam, silt, sandy clay loam, clay loam, silty clay loam, sandy clay, silty clay, and clay). Soil textures are classified by the fractions of sand, silt, and clay in a soil.

Therefore, most living things on land depend on soil for their existence.

What type of soil is chalk?
Chalky soil is comprised mostly of calcium carbonate from sediment that has built up over time. It is usually shallow, stony, and dries out quickly. This soil is alkaline with pH levels between 7.1 and 10. In areas with large deposits of chalk, well water will be hard water.
What are the three properties of sandy soil?

Signs of healthy soil include plenty of underground animal and plant activity, such as earthworms and fungi. Soil that is rich in organic matter tends to be darker and crumbles off of the roots of plants you pull up. A healthy, spread-out root system is also a sign of good soil.
