Alternative/Renewable/NonRenewable

Natural Resources are

• materials in the environment that are harmful to people
• are materials in the environment that are useful to people
• neither nonrenewable or renewable resources
• not oil, water, oxygen, and sunlight

Renewable resources are natural resources that

• take thousands/millions of years to produce
• once they are used up they can't be produced ever
• can be produced again in our lifetime (80 years)
• are coal, oil, natural gas

The following are renewable resources

• coal, oil, biofuel
• trees, animals, water
• coal, oil, petroleum
• oxygen, soil, fossil fuels

Conservation is

• the practice of increasing the use of natural resources in order to use them
• the practice of increasing the use of natural resources in order to save them
• the practice of decreasing the use of natural resources in order to use them
• the practice of decreasing the use of natural resources in order to save them

Nonrenewable resources are natural resources, such as fossil fuels, that will eventually be used up and can never be replaced

• True
• False

Fossil Fuels are fuels

• formed from the decaying remains of plants only
• formed from the decaying remains of plants and animals that were compressed over a short period of time
• formed from the decaying remains of plants and animals that lived millions of years ago
• formed from decaying food

Fossil fuels, minerals, and metals are

• nonrenewable resources
• renewable resources

Alternative Energy sources

• take the place of nonrenewable resources
• take the place of renewable resources

Some examples of alternative energy resources are

• wind, solar, fossil fuels
• biofuels, hydroelectric, geothermal
• metals, minerals, fossil fuels
• metals, solar, wind

A disadvantage of wind energy is

• that the wind will blow too hard
• it will produce electricity
• it will help our environment
• at certain times, the wind may not be blowing
