Let's put it this way--If you placed a wheelbarrow full of Golf ball sized limestone outside, dust and windblown plant material, water, even bird manure, would accumulate next to the rocks. Soon plants would be growing among the rocks, furthering erosion through root growth, and freeze/thaw cycles would break the rocks even further. The acidity of the rainwater would gradually dissolve the limestone into smaller and smaller particles. The rate of erosion might be noticeable in a year's time, but would be dependent on the climate of the area where the rocks are placed. In an arid climate the rate of erosion might be very slow. Speed it up by putting it in a wet climate. In a related note, the loess, or windblown dust accumulation rate in Illinois during the last glaciation period was, on average, roughly 1" for every thousand years, resulting in 20' or more (in places) of extremely fertile soils worked by today's farmers.
subsoil
It takes about as long as a water cycle
The formation of buttes occurs on a geological timescale. This can be from millions to hundreds of millions years.
Ordinary ground water? A few days can see the algae form.
There are many types of fossilization. Some take a surprisingly few number of years, and others occur over periods of millions of years.
Subsoil water is when the subsoil contains water.
subsoil
The three layers that form the soil profile are topsoil, subsoil, and bedrock. Topsoil is the uppermost layer rich in organic matter and nutrients, while subsoil is the middle layer with less organic material and more minerals. Bedrock is the solid rock layer found beneath the soil layers.
Bedrock is formed from the consolidation of solid rock materials, such as granite or basalt, through processes like cooling and pressure. Subsoil is formed from the weathering and decomposition of bedrock, which creates a layer of material composed of minerals and organic matter.

A caliche is a crude form of sodium nitrate used as a fertilizer, or a layer of hard clay subsoil or sedimentary rock.

Three layers of the Earth are soil, subsoil and bedrock.
Subsoil has less nutrient both SOM or mineral fertilizer more accumulate on top soil. In certain climate condition (arid and semi arid) the evaporation is higher than precipitation can take up soil mineral and reached the subsoil. So, the pH can be alkaline soil which is not favourable for plat growth.
Faults can form virtually instantaneously.
