Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life. Earth's body of soil, called the pedosphere, has four important functions:
as a medium for plant growth
as a means of water storage, supply and purification
as a modifier of Earth's atmosphere
as a habitat for organisms
All of these functions, in their turn, modify the soil and its properties.
Soil is also commonly referred to as earth or dirt; some scientific definitions distinguish dirt from soil by restricting the former term specifically to displaced soil
