100

Name three groups that depend on natural resources.

People, plants, and animals.

100

Name two renewable resources that are available almost all of the time.

Sunlight and wind

100

Name three fossil fuels.

Coal, oil, and natural gas.

100

What can burning coal, oil, and natural gas release into the air?

Pollution

100

What are the three Rs of conservation?

Reduce, reuse, and recycle.

200

How do people use soil and water to meet basic needs?

People drink water and use soil to grow food.

200

How do wind turbines make electricity?

They use moving air to make electricity.

200

What makes a resource nonrenewable?

It forms so slowly that people cannot replace it within a human lifetime.

200

What can some gases trap in the atmosphere?

Heat

200

What does it mean to reuse an item?

Use it again instead of throwing it away.

300

Give an example of how people use natural resources to travel.

They use oil to make gas to power cars and other vehicles.

300

Why should people use clean water carefully even though water is renewable?

Clean water can be limited in some places, and pollution can make it less usable.

300

How long does it take fossil fuels to form?

Millions of years.

300

Name two things climate change can affect.

Weather patterns, ice, oceans, plants, and animals

300

Give two ways people can conserve resources at home.

Turn off lights when leaving a room and avoid wasting water.

400

Give an example of how people use natural resources to build.

People use wood, stone, and metals to build homes and roads.

400

Explain why forests and soil must be managed wisely even though they can renew.

Forests need time to regrow, and cutting too many trees too quickly can harm animal homes and forest recovery. Healthy soil also takes a long time to form, so farmers can protect it with cover crops and by preventing it from washing away.

400

Name two nonrenewable minerals or metals and describe where they are found.

Iron and copper are taken from rocks in the ground.

400

Describe two ways mining or building can affect land and wildlife.

Forests may be cleared, and animal habitats may be damaged or lost.

400

What does conservation mean?

Using resources carefully so they last longer and nature can stay healthy.

500

What are natural resources?

Materials and sources of energy that come from Earth or nature.

500

What is a renewable resource?

A resource that nature can replace over time.

500

Why can using up a nonrenewable resource in one place create a lasting problem?

The resource takes a very long time to form, so people cannot quickly replace what they have used.

500

Name 3 natural resources that pollution can harm

Air, water, and soil

500

Explain how using renewable energy and saving energy can reduce the need to burn fossil fuels.

Using more solar and wind power provides energy from renewable sources, reducing the need to burn fossil fuels.
