Depending on geographic location, the natural build-up of one inch of topsoil requires about 400 - 10,000 years. Certain locations can require less, and others, even more.
recover from what?
There is no guarantee that it will ever recover. The layer of topsoil in a rainforest is extremely thin. Because there is so much competition for food in the forest, little material builds up to form topsoil. When the trees are cut down and the thin layer of topsoil is exposed to sun, wind, and water, it is more susceptible to erosion. When the topsoil disappears, the land becomes un-arable, and becomes essentially desert.
This depends on what type of topsoil, its composition, the surrounding climate, etc. But usually it'll take about 800-1000 years for an inch to form.
as long as it takes to recover from your mom
hundreds of years
350-500 years
6000 to 12000 years ago.
long enough
how long does it take to heal after a pelvic surgeory
I am guessing it will take about 1-3 weeks to recover it deppending on size or form.
It will take a week to cover, a month to fully recover
It took then a long time
It took over ten years to recover after the Shaanxi earthquake
