Title: Re: Why is soil formation slow? Post by: Rohcodom on Dec 5, 2017 The formation of soil begins when the parent material is exposed to the effects of the atmosphere, hydrosphere, and biosphere. Parent material can be lava or volcanic ash; rock or sediment deposited by glaciers; wind-blown dunes; sediments deposited by rivers, in lakes, or in the ocean; or, perhaps most commonly, any type of bedrock, the continuous mass of solid rock that makes up Earth's crust.
