Which is a nonrenewable resource?

• oil

• sunlight

• water

• wood

Which are most responsible for creating acid rain pollution?

• nuclear power plants

• coal-burning power plants

• hydroelectric power plants

• wood-burning power plants

The table shows the estimated energy production (in quadrillions of BTUs) from fossil fuels over a 20-year period.

Which conclusion is best supported by the data?

• Dependency on oil has increased, therefore energy production from oil is increasing.

• Dependency on oil has increased, therefore energy production from natural gas is decreasing.

• Dependency on coal has increased, therefore energy production from coal is increasing.

• Dependency on coal has increased, therefore energy production from natural gas is decreasing.

How would a large increase in the salinity of an estuary most likely affect the ecosystem of the estuary?

• All organisms would die.

• All organisms would continue to live as they now do.

Which would indicate the water in a lake is not safe for drinking?

• many varieties of fish in the lake

• high dissolved-oxygen levels in the lake

• cold water temperature of the lake

• high turbidity levels in the lake

Which best explains why all of the Earth’s freshwater is not available for human use?

• Most of Earth’s freshwater is only in lakes.

• Most of Earth’s freshwater is underground.

• Most of Earth’s freshwater is still in the water cycle.

• Most of Earth’s freshwater is frozen water

How can upwellings improve fishing for ocean fishermen?

• They cause the ocean water to get warmer.

• They cause ocean currents to remain calm.

• They bring nutrients from the cold, deep ocean waters

• They bring ocean currents from the equator.
