Final Review Part 3

What process is most responsible for different weather conditions that occur on Earth?

• The flow of deep ocean currents from the poles to the equator

• The gravitational pull of the moon and sun on Earth

• Heat from the Earth’s core rising through the mantle

• Convection currents in the atmosphere

• Melting of glaciers

• Lightning

Which human activity adds acid rain to the water cycle and reduces the availability of freshwater?

• Building homes

• Destroying forests

• Burning coal in factories

• Desalinating ocean water

Which would most likely cause the depletion of a freshwater resource over time?

• An increase in the limitations on fishing in freshwater lakes

• An increase in the cost of freshwater usage

• Restricting the use of local freshwater

• Using freshwater for irrigation

In the hydrological cycle, which process contributes to a decrease in groundwater levels?

What could happen if fertilizers were accidentally introduced into surface water?

• Algae blooms could form in the groundwater

• Spring water could be used to dilute the strength of the fertilizer

• Infiltration from runoff could lead to groundwater contamination

• Natural minerals in groundwater could control the absorption of any contaminants
