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.

Which is most likely a major concern associated with burning fossil fuels?

• Burning fossil fuels can pollute the oceans.

• Burning fossil fuels can remove harmful chemicals from precipitation.

• Burning fossil fuels can remove carbon dioxide from the atmosphere.

• Burning fossil fuels can produce smog, which can cause respiratory illnesses.

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

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.

If a lake has excess levels of phosphates and nitrates in its water, what will most likely result?

• The temperature of the lake water will decrease.

• The turbidity levels of the lake will decrease.

• The dissolved-oxygen levels in the lake will increase.

A geologist identifies the identical index fossils in rock layers from two different areas. Which conclusion is best supported by this discovery?

• The deposition rate of the two rock layers was identical.

• The fossil organism evolved independently in the two separate areas.

• The two rock layers were deposited at approximately the same time.

• The index fossil will also occur in sediment deposited on top of these rock layers.
