because the earth covers them up an with in mill. years they come back up
Millions and millions of years
It takes millions of years to make 1cm3 of soil.
no it will stay good for millions of years
Thousands of years.
Craters last for millions of years on the surface of the moon because the moon does not have an atmosphere. Saying this the moon does not have anything able to fill in the craters such as soil or rain.
Yes,igneous rocks are also changed into soil.But they take millions of years to change into soil
Most fossils are found in sedimentary rock. This is because sediments (soil, sand, etc) pile on top of bones and then solidify into rock, over time, preserving fossils. Because these generally remain buried very deep, it does make it easier to find fossils in areas where the ground has been pushed upward by the formation of mountain ranges. Thus, sedimentary rock is nearly always the material fossils are found in, and mountains make it a little easier to find fossils.

When plants and animals die, their organic matter decomposes through the action of bacteria, fungi, and other decomposers. This process releases nutrients back into the soil, which can then be taken up by plants to continue the nutrient cycle.
Soil formation is a continuous process that occurs over thousands to millions of years through the weathering of rocks and organic matter decomposition. The formation of soil began billions of years ago as Earth's surface evolved and continues to this day.
