• An insect preserved in amber

Which of the following terms best describes body fossils?

• Widespread
• Made of stone

Why are deserts, tar pits, and ice good places to find body fossils?

• Most ancient organisms lived in these enviornments
• Bacteria and other decomposers cannot thrive in these environments 
• Many ancient organisms traveled to these places to die
• The largest ancient organisms lived in these environments 

In order to form a fossil, an organism must usually ______ quickly after it dies.

• Decompose
• Go extinct
• Rot
• Be buried

What can you conclude from the fact that so many fossils involve shells, skeletons, and teeth?

• Most  organisms on earth have shells, skeletons, or teeth
• Bacteria and decomposers consume these parts first after an animal dies
• These parts decay slower than other body parts
• These parts are more likely to be buried in ice than other body parts

• A replica of your teeth made at the dentist's office
• A bone your dog buries in your backyard
• An insect trapped in tree sap

what can you infer from the fact that fossil fuels are carbon-based?

• Over time flesh turns into carbon
• Most life on earth is made from carbon
• Trees are made of carbon, but animals are not
• Swampy environments are carbon-poor environments

What two forces can turn fossils into fossil fuels?

• Lift and thrust
• Wind and rain
• Temperature and pressure
• Motion and time
