Question:
How old is soil and how long does it take to become soil?



Replies:
That depends on lots of things, like what is in the soil (composition), humidity, rainfall, plant growth, animals, etc. I don't know where you are, but where I am (Illinois), the soils formed in a vast prairie system after the ice sheets retreated, so it took several thousand years for these soils to form.
