• B. Coal, Oil, and Natural Gas
• C. Electricity, Gasoline, Petroleum
• D. Coal, Oil, Non-renewable Resources

Fossil Fuels formed over long periods of time after particles in water settled to the sea floor and formed marine mud.  What kinds of particles needed to be present in the marine mud in order for fossil fuels to form.

• A. Mostly sand and a few small bits of wood
• B. Mostly decaying organisms
• C. Mostly lava and a few sedimentary rocks
• D. Mostly metal minerals

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?

• A. Sedimentary rock is made of layers.
• B. Sedimentary rock is cemented bits of rock.
• C. Sedimentary rock is often limestone.
• D. Sedimentary rock is common in Texas.
