• greenhouse

• globalization

• habitat restoration

Multiple Choice

The climate of a location can be described by its

• What type, how much and when precipitation falls

• Average air temperature

• Humidity

• All of these.

Multiple Choice

Climate is more predictable than weather.

• True

• False

Multiple Choice

Why should you keep products that create hazardous waste in their original containers?

• The labels on the containers provide instructions on how to properly dispose of them.

• The containers are a pretty way to display the product.

• The original containers are cheaper than buying new containers.

Multiple Select

Select all possible answers:

What factors determine the availability of a resource?

• Where the resource is located.

• How much the resource costs.

• Politics involving nations that have the resource.

• How much of the resource there is.

Multiple Choice

Why do politics play such an important role in resource availability?

• Resources are available everywhere, so everyone has access and politics are not involved.

• Resources can't be withheld, so everyone has access.

• Since resources aren't available for everyone, the country that has the resource has the ability to control who gets it.

Multiple Choice

• True

• False

Multiple Choice

What is a renewable resource?

• A natural resource that is quickly replaced

• An unnatural resource that takes time to replace

• None of these

• A resource which is exhaustible

Multiple Choice

• None of these

• Heat boils water to make steam, turns generators, spins turbines, makes electricity

• Creates elements that combine to release radioactive material that spins turbines, turns generators, makes electricity

Multiple Choice

Negative environmental consequences of nuclear power include

• Air pollution, including carbon emissions

• All of these

• Waste that is radioactive for hundreds of thousands of years

• Ozone depletion

Multiple Choice

The Sun is the source of energy in

• Nuclear power

• Fossil fuels

• None of these

• Geothermal energy

Multiple Select

Select all possible answers:

In what ways do dams change a river's ecosystem?

• The slow the release of silt from upstream to downstream when a dam blocks the river.

• The part of the river downstream of the dam becomes flooded and deeper than it previously was.

• There is no change to a river's ecosystem.

• The area before the dam becomes a deep lake or reservoir and floods an area where there previously was just a river.

• Fish and other river life might not be able to survive when water flow is cut off.

Multiple Select

Select all possible answers:

What are some disadvantages of wind power?

• Wind turbines are expensive and can wear out quickly.

• Wind power doesn't release carbon dioxide.

• Wind power doesn't release pollutants.

• Wind does not blow all the time, so either energy must be saved for later use or another form of energy must be available.

• True

• False

Multiple Select
