They're preserved due to the fact that they're inside the ground protected by a barrier of sediment.

How long does it take to form a fossil?
There are many types of fossilization. Some take a surprisingly few number of years, and others occur over periods of millions of years.
Why is it important to conserve non-renewable sources of energy such as coal and oil?
Cause then we will run out and it will take like a million years to get it backas they are limited we have to conserve it
How long does it take for a butte to form?
The formation of buttes occurs on a geological timescale. This can be from millions to hundreds of millions years.
How Many MonthsYears take up a million Hours?
There are 8,760 hours in a 365 day year. This would mean that 1 million hours would take 1369.86 months or 114.155 years to pass.
Why are more fossils not found?
Asking why there are more animal fossils presupposes that there are more animal fossils than plant fossils. This is not the necessarily case. Plant fossils are actually much more common than animal fossils. If you consider the distribution of biomass in modern ecosystems, it is clear that plants are the dominant kingdom (e.g if you walk into a rainforest, you see hundreds of trees, but few large animals). This distribution is a necessity for any functioning ecosystem because the plants are primary producers (other species need them for survival).Lignite, a low grade coal, is composed entirely of semi-compacted plant fossils. It is so common that it is often burned for use as fuel.This being said, plants also decay faster than animals given the same initial conditions (they do not typically have hard parts like bones), so the percentage of plants that are fossilized should be less than the percentage of macroscopic animals. Since plants so greatly outnumber animals, however, this does not make fossil animals more common.Addendum:It matters too whether one is discussing microfossils or fossils large enough to see or whole fossils or merely a fossilized leaf. See related questions.Plants have softer bodys parts than animals

Why are fossils considered nonrenewable?
Because fossil fuels take hundreds of millions of years to form under the Earth's surface. It will take another million years for more to be produced, so we only have a limited supply. Eventually, more fossils will be made, but by then we will have run out by how much we use them now. If we stop using them so much than we wont die like we are going to. So essentially, all fossil fuels are considered non-renewable.
