Soil Composition and Importance Quiz

Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that supports the life of plants and soil organisms.

Soil is a product of several factors: the influence of climate, relief (elevation, orientation, and slope of terrain), organisms, and the soil's parent materials (original minerals) interacting over time.
