How are fossils created?

• Traces of organisms get turned into stone.
• Dead organisms are quickly buried for millions of years.
• Animals get trapped.
• All of the above

Some students made a model to show one of the first steps in the formation of sedimentary rock.  The students pour 2 cm of light-colored sand into a clear plastic box.  Then they add 1 cm of gravel.  Finally, they pour 2 cm of dark-colored sand on top of the gravel.  Which characteristic of sedimentary rock does this model best show?

• Sedimentary rock is made of layers.
• Sedimentary rock is cemented bits of rock.
• Sedimentary rock is often limestone.
• Sedimentary rock is common in Texas.

Coal often forms where once there was swamps.  What characteristic of swamps is important to the formation of coal?

• High Temperature
• Abundant Plant Life
• Frequent Rains
• Reptile Predators

A student creates a model of the formation of fossil fuels by first placing a layer of leaves, representing organic matter, in the bottom of a cup.  What step will come next in the model?

• Pouring water over the leaves to model washing away by rivers
• adding sand on top of the leaves to model burial in sediments
• Burning the leaves to model the decay of organic matter
• Putting the leaves in the freezer to model conditions on top of mountains

Which layer formed first?

• Rock Layer W
• Rock Layer X
• Rock Layer Y
• Rock Layer Z

What feature is the same in the formation of many sedimentary rocks and all fossil fuels?  Many sedimentary rocks and all fossil fuels -

• require material to be buried and exposed to heat and pressure
• are made out of organic material that stores the sun's energy
• form where there are frequent earthquakes and volcanic activity
• are produced high in the mountains where temperatures are low

Sedimentary rocks form when broken bits of other rock are deposited and then -

• buried and squeezed and cemented together
• melted by the heat of the Earth's core
• completely dissolved in the salt water of the ocean 
• used by humans as a natural resource
