Renewable and Nonrenewable Energy Resources

What are natural resources?

• Materials created by humans.

• Substances found in nature that are useful to humans.

• Only living things like plants and animals.

• Resources that can never run out.

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

• Coal

• Iron ore

• Water

• Crude oil

What is the key difference between renewable and nonrenewable resources?

• Renewable resources are always found in water, while nonrenewable resources are found on land.

• Renewable resources can be replaced within a human lifetime, while nonrenewable resources cannot.

• Nonrenewable resources are always more expensive than renewable resources.

• Renewable resources are only used for food, and nonrenewable resources are only used for energy.

Which of these is considered a nonrenewable resource?

• Fish

• Rubber trees

• Sunlight

• Natural gas

What is a negative environmental impact of burning fossil fuels?

• It increases the amount of oxygen in the atmosphere.

• It helps new plants grow faster.

• It increases greenhouse gases, which can raise Earth's temperature.

• It creates more water for the water cycle.

Which of the following is NOT considered a renewable energy resource?

• Sunlight

• Wind

• Natural gas

• Flowing water

What is the primary function of a photovoltaic cell in generating electricity?

• It converts heat energy from the sun into mechanical energy.

• It transforms radiant energy from the sun directly into electrical energy.

• It uses the sun's energy to heat water, which then drives a turbine.

• It stores solar energy as chemical energy for later use.

What is the biggest challenge associated with using wind energy to produce electricity?

• Wind turbines are very noisy.

• Wind speeds are not always consistent.

• Wind turbines take up too much space.

• Wind energy is too expensive to set up.

What is a potential negative environmental impact of building a hydroelectric dam?

• It can cause air pollution.

• It can lead to increased wind speeds in the area.

• It can disrupt local ecosystems by flooding areas and changing water flow.

• It makes the water too cold for aquatic life.

Where does geothermal energy primarily come from?

• The movement of ocean tides.

• The burning of organic materials.

• Heat and steam from inside the Earth.

• Sunlight absorbed by the ground.
