✔We say that it takes 500 to thousands of years to create an inch of topsoil. The reason is that soil is often derived from rock. The rock has to be broken into small pieces first. This happens by physical weathering: things like freezing and thawing in colder climates, and chemical weathering in warmer climates. Once cracks form in the rock and plants can take hold, the plants continue to break the rock into smaller pieces by root action and start to add organic matter. Chemical weathering also continues, turning the rock pieces into the sand, silt, and clay particles that make up our soil.
