What is created when chemicals in air pollution react with water in the atmosphere?

• smog

• greenhouse gases

• toxins

• acid rain

How is most household electricity generated in our current society?

• household electricity is generated by power lines

• the kinetic energy of wind is transferred into electrical energy

• solar energy is transferred into electrical energy

• the burning of fossil fuels transfers chemical energy into kinetic energy

Which of the following processes decreases the amount of atmospheric carbon dioxide?

• burning fossil fuels

• deforestation

• photosynthesis

• habitat destruction

Chemical processes in factories sometimes add thermal energy to water. When the water in a river or lake increases in temperature, this could affect the plants and animals living in the water because -

• warm water holds less oxygen than cool water

• warm water holds more oxygen than cool water

• aquatic plants and animals can live in a broad temperature range

• all the aquatic plants and animals affected will die

A coal-fired power plant uses water from a local lake to cool the steam produced back into liquid water. This mixture of hot water and lake water is dumped back into the lake. Trout and bass living in the lake have been dying off since the plant was opened. Based on the evidence, what sort of impact is the chemical reaction the plant using having on the lake?

• greenhouse effect

• thermal pollution

• soil degradation

• global warming

Which of the following is considered a renewable source of energy?

• wind

• coal

• natural gas

• oil

Which of the following does not contribute to global climate change?

• Burning of fossil fuels

• Industrial waste released into waterways

• Release of methane from landfills and livestock

• Pollution from vehicles and other forms of transportation

The plants near a landfill are slowly dying. What could explain this?

• Air pollution from the landfill damages the leaves of the plants.

• The landfill uses up water in the area, causing the plants to dry out.

• Chemical end products from the landfill seep into the soil and are absorbed by the plants.

• The landfill creates greenhouse gases in the area that make it too hot for the plants.

A nuclear power plant dumps waste hot water into a nearby lake. The result of this action is that -

• the warm water will cause the metabolism of local fish populations to decrease, reducing the need for dissolved oxygen in the water.

• the surrounding ecosystem will be unaffected as long as the water is free from pollution.

• the amount of dissolved oxygen in that part of the lake will decrease, reducing the number of local fish populations.

• the amount of dissolved oxygen in that part of the lake will increase, causing the local fish population to grow.
