Fossils and Fossil Fuel Review

Many people encourage others to carpool or to use public transportation, such as buses. How do these options help conserve nonrenewable resources?

• We cut down fewer trees since we need fewer roads.

• Taking the bus is less expensive than owning a car.

• These options put fewer pollutants into the atmosphere.

• We use less gasoline, which is made from fossil fuels.

Why is coal considered a nonrenewable resource?

• The processes that make coal are no longer happening.

• It took millions of years to produce the coal we use now.

• Coal is made from plants that went extinct long ago.

• It is dangerous and expensive to dig coal from the ground.

Which part of the pencil is made from a renewable resource?

• The graphite, made from a mineral

• The shaft, made from wood

• The ferrule, made from metal

• The eraser, made from fossil fuel

Oxygen is considered a renewable resource because it–

• is constantly cycling through the atmosphere.

• is the most abundant gas on Earth.

• is extremely flammable and necessary for burning

• has always been part of Earth’s atmosphere.

Which of the following is an example of conserving a renewable resource?

• Making diamonds in a laboratory

• Melting aluminum cans to make new cans

• Recycling paper to avoid cutting down trees

• Driving electric cars that do not use gasoline

Studying the fossils of a certain region is best for giving scientists evidence about which of the following characteristics of that area?

• The rates of weathering and erosion

• The type of environment long ago

• The number of earthquakes during the year

• The kind of climate in the future

The most reasonable conclusion for scientists to draw after finding fossil fish bones in the sedimentary rocks beneath a forest would be that in the ancient past this area was covered by–

• sand

• rocks

• water

• plants

In the rock layers below the Antarctic, a region currently covered in ice, scientists have discovered the remains of plants that usually live only in very warm climates. What is the most reasonable conclusion for scientists to draw from this evidence?

• The Antarctic will be covered in ice for millions of years.

• The climate in the Antarctic was very different in the past.

• These plants have adapted to live in the Antarctic.

• The Antarctic has daylight for only six months of the year.

The chart above shows the kinds of fossils found in a certain region at different depths in the rock layers. The most recent environment for which this sequence of fossils gives us evidence was most likely what?

• Ocean

• Desert

• Forest

• Lake

According to the evidence, which of the following lived in this area at the same time as the dinosaurs?

• Ferns

• Pine trees

• Sharks

• Cactus
