Earth's Resources: Sedimentary Rocks, Fossil Fuels

Fossil Fuels are formed...

• From the remains of organisms
• By high winds and temperatures
• In shallow areas over short period of time.
• In shallow areas over short periods of time.

Coal is a fossil fuel that is formed from...

• Water eroding the land
• Meteors hitting Earth.
• Repeated volcanic eruptions.
• The decay of dead plants and animals

Which of the following is NOTa fossil fuel?

• Alcohol
• Coal
• Natural Gas
• Oil

What is the difference between compaction and cementation?

• Cementation is the pressing of layers of sediment into sedimentary rock; Compaction is the minerals in water sticking sediments together to form sedimentary rock.
• Compaction is the pressing of layers of sedimentary rock; Cementation is the pressing of layers together deep in the earth with heat to form sedimentary rock.
• Compaction is sediments melting together to form sedimentary rock; cementation is the minerals in water sticking sediments together to form sedimentary rock.
• Compaction is the pressing of layers into sedimentary rock; Cementation is the minerals in water sticking sediments together to form sedimentary rock.

What causes the pressure necessary to form sedimentary rocks?

• Chemicals in the rock
• Temperatures inside the earth
• Weight from rocks above
• Water flowing over rock

A student wants to model the formation of sedimentary rock.  What will the student need?

• Sediments and pressure
• Sediments floating in water
• Sediments heated in water
• Sediments dissolved by the sun

The layers of sedimentary rock were found in this order beneath the ground.  Which layer formed first?

• Layer A
• Layer B
• Layer C
• Layer A, B, and C were formed at the same time.

Oil is often found beneath the ocean because...

• The salt in ocean water will change to oil over thousands of years.
• The dead organisms mix with sand and are turned to oil by heat and pressure.
• The cold temerature at the bottom of the ocean changes shells into oil.
• The smaller organisms are eaten by larger organisms whose digestive systems change them into oil.

Which two processes contributed to the formation of sedimentary rocks?

• Compaction and Melting
• Cementation and Molding
• Compaction and Cementation
• Molding and Melting
