Fossil Fuel

Coal is formed when plants die and decompose into swampy areas. Eventually there is many layers forming a material called peat. Seas and great rivers cause deposits of sand, clay and other mineral matter to accumulate, which covers the peat. Sedimentary rocks were formed, and the pressure caused by their weight squeezed water from the peat. The heat associated with it gradually changed the material to coal.

-They drove over fire, and their tires didn't melt
-They outran lava, and a pyroclastic flow
-The boat wouldn't have lasted that long in the acid

-The fact it was dark in the day time
-It's correct grandmother would have died if she went in the acid

Fossils













This would be original remains because the actual tissue of the bugs are reserved inside the amber.



This would be a Trace Fossil because it's formed from mold and cast process. It's indirect evidence of life.

3-1-6-2-4-5

3 is first because it is an intrusion and has gone through many layers.
1 is next because it is at the very top and would be the closest to 3.
6 is after because it's right below 1.
2 would follow because it's another intrusion.
4 comes along next.
and 5 is last.
