Is Dirt Just Ground Rock

Soil is not simply weathered rock. Soil is a dynamic natural resource. It is comprised of minerals, water, gases, organic material, and living creatures including soil microbes and tiny animals. Calling a soil “mature” doesn’t mean that soil formation has stopped.

Is dirt made of tiny rocks?

Dirt is a mix of tiny rocks, decayed organisms, living organisms, air, and water.

How is new dirt made?

Over hundreds of years, rocks break down into tiny grains, and these small grains, mixed with plant and animal matter — decayed roots, leaves, dead bugs and worms, and other organic matter thrown in, along with water and air — is what we call dirt or soil.
