It depends on where your at, in the rainforest it can happen in a year, while in other places take hunreds of years.

Naturally, our peace-loving country, not wishing to take initiative of breaking the pact, could not resort to perfidy.
If this is for an AP Environmental class, the answer is several centuries to several thousands of years. I found the answer on page 156 of "Living in the Environment - 14th Edition." It starts forming from pioneer species.
I think your question could be re-phrased as the difference between long exposure photography and deep depth of field photography. A long exposure is where a long exposure time is used, either to record movement over a period of time, for artistic effect, or in order to provide a greater depth of field, (deep focus), achieved by using a smaller 'F' number on the camera, which provides a smaller aperture for the light to pass through. ********* For some, it relates to what is technically known as hyperfocal distance (a point of focus deduced and utilized to maximize depth of field beyond normal). IMHO, "deep focus" is a mis-nomer as you can only focus on one plane within the field of view. Anything in front or behind is not in focus; however, it may be acceptably sharp to the eye. This is depth of field. There is also "depth of focus", which is different, though related. Methinks neither depth of field nor depth of focus should be referred to as deep focus
500 to 1,000 years
100 years
It takes about 1,000 years
It takes about 1,000 years
three hundred years
depending on the climate and other factors it takes about 1,000 years
because it can take minerals from the soil
Mostly when a river flows through a flat area with soft soil.
dry hot or warm because it is hot and take a long time to form

Soil is formed by decomposition of remains of plants and animals buried deep underground,,, by various micro-organisms & is indeed a very slow process..... It is believed dat it takes 800-1000 yrs to form 1 cm of soil rich in organic materials!!!!!!!!!!!!!!!
