How does time affect soil

Over time there can be dead animals and leaves or other things that could have been decomposed into that soil.

The soil could no longer have minreals and nutrious things in it.People or animals could run over the dirt .wind or rain could move the soil.Animals or plants could leave there skeltons in the soil producing fossils.

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
