Compare the differences between renewable and nonrenewable resources.

Answer explanation

Renewable resources are things that can never be used up, like solar and wind energy, or that can be replaced in our lifetimes, like plants and animals. Nonrenewable resources take millions of years to make naturally, are typically located deep in Earth’s crust, and are costly to find.

Describe the possible impacts in the future of using a renewable resource.

Answer explanation

By using renewable resources, which tend to be cleaner than nonrenewable resources, the air quality will be better and there should be less water pollution. Since there are many options, dependence on foreign countries for energy would be decreased.

People try to conserve some resources, like fossil fuels, because they are not replaceable. Why can’t these resources be replaced?

• It is impossible to extract more from the earth.

• No one can afford to buy more of them.

• Processes that make them take a long time.

• They must be transported long distances.

People move into and begin living in an area that previously had no human activity. What will most likely be the effect on the amount of water?

• The amount of freshwater suitable for drinking will increase.

• Water will be more evenly distributed in the area.

• There will be less available for other living things.

• Most of the freshwater in the area will be converted to saltwater.
