What name is given to fossils that are widespread geographically?
Fossils that are widespread geographically are commonly referred to as cosmopolitan fossils. These fossils are found in multiple locations around the world, indicating a broad distribution during the time period in which they were alive.
How do scientists use fossils to tell them how the earth has change over millions of years of history?
They study the bones and try to figure out what animal it might have been. They can also study the rock around the fossil to tell when the rock existed and therefore when the animal was alive. They can also study the type of rock to give an idea of what the animal liked or disliked.
Where are the earliest fossils found?
In undisturbed strata, the oldest fossils will be the deepest from the surface.
Are fossils made from rocks?
Fossils are made of rock yes. Most commonly this happens when a living organism (plant or animal) dies and its body is buried in mud before it has a chance to decay. The mud hardens into rock quickly, while the dead body slowly breaks down and leaves behind a hollow impression in the now solid rock around it. This kind of fossil is called a mold fossil, as the hollow remains empty like a jello mold. A cast fossil is when later other mineral rich water fills up the mold eventually turning the hollow into a solid rock of a different kind than the rock around it. Trace fossils are made in the same way but come from things made by a living organism such as footprints or tracks, burrows or nests, eggshells and droppings. These fossils are not of the animal itself but preserve evidence of the animal behavior.

How big does lava can affect?
Lava has a much more intense, but much smaller effect than ash from a volcana eruption. The lava only effects the immediate area around the volcano, because it cools and hardens quickly.
How does the environment affect the formation of fossils?
the environment can rain a lot and fossils can not become fossils when theres a lot of water around
Why do some dead animals not become fossils?
The vast majority of dead animals are not fossilised. For something to become a fossil it has to die under very special circumstances. If an animal living in a forest dies it will quickly be absorbed by the other life around it, insects, fungi, bacteria all play their part in recycling the energy provided by the dead animal. The same happens on the plains and under the seas, though the organisms doing the recycling will be different.
How do you know this is a fossil?
It is usually pretty obvious, for fossils are eathier animal or plant. Some of the most commen fossils are shells, trilobites and ferns. If the fossil is very feint, try CAREFULLY carving around it with a chisel or sometype of sharp tool. Good Luck!
