When humans burn fossil fuels, they use stored energy from the remains of ancient plants and animals. Why are these energy resources considered nonrenewable?

• Fossil fuels can never be replaced.

• Fossil fuels are used over and over by people.

• Fossil fuels are found in an unlimited supply on Earth.

• Fossil fuels can only be replaced over millions of years.

Read the passage about solar energy.

Solar energy is energy that Earth receives from the Sun. This type of energy can be used for many things. Using solar panels, it can be used to make energy, or it can reduce the amount of energy needed for things.

Which statement best describes the use of solar energy to heat water for a house?

• Solar panels that heat water trap energy from the air to reduce the need for non-renewable energy sources.

• Solar panels that heat water use the Sun's radiant energy to reduce the need for non-renewable energy sources.

• Solar panels that heat water use the Sun's thermal energy to reduce the need for non-renewable energy sources.

• Solar panels that heat water use electricity from the home to reduce the need for non-renewable energy sources.

Many people visit Florida because of the beaches and warm weather. Which type of renewable energy would be found in large amounts in this type of climate?

• hydroelectric

• natural gas

• oil

• solar

The pictures show a forest before and after deforestation, a process where many trees are cut down.
Which of the following best explains why trees are called a renewable resources?

• If a tree is cut down, a new tree can be planted in its place.

• If a tree is cut down, the animals that depended on the tree will help the tree grow back.

• Only humans use trees, so tree populations will never fall below the number that are needed.

• Only paper is made from trees, so the tree population will never run out.

The table shows Harrison's list of which natural resources are used to make four different containers.

If Harrison wants to use only containers that come from renewable resources, which of the containers should he use?

• either the glass bottle or the aluminum cup, because they both come from renewable resources

• either the paper cup or the plastic bottle, because they both come from renewable resources

• the paper cup, because it is the only container that comes from a renewable resource

• the plastic bottle, because it is the only container that comes from a renewable resource

Why is it important for scientists to find sources other than fossil fuels for energy production?

• Not enough organic material exists to replace fossil fuels.

• The formation of fossil fuels results in pollution.

• Fossil fuels store energy for a short period of time.

• It takes a very long time for fossil fuels to form.
