How long does soil development take?

Answer 1

Soil is really just decade leaves, moss, and dead matter, that take YEARS to break down, but still, there is a lot of decade matter from millions of years ago, so, I think we are all covered.

Soil development can take anywhere from decades to thousands of years, depending on factors such as climate, type of parent material, vegetation, and topography. It is a slow and continuous process involving weathering of rocks, addition of organic matter, and activities of organisms.
