How can engineers at a solar farm maximize energy collection from photovoltaic cells during the day?

• by placing the cells closely together so that they partially shade each other during the afternoon

• by having the cells track the Sun's path across the sky so they are always directly facing the sun

• by using the cells only in the late fall and winter, when the sun is most directly overhead

• by using the cells only in the morning and late afternoon, when the sun's rays are least intense

In a local town, more than 50% of home owners installed solar heaters to keep their homes warm instead of using electricity from coal that comes from a different state.

How will this decision impact the local environment?

• There will be a decrease in local deforestation.

• There will be an increase in acid rain as result of the increased coal conservation.

• There will be an increase in local smog from the coal fired power plants.

• There will be a decrease in local greenhouse gas emissions.

A dam was constructed across a river to meet the power needs of an area. What is the most likely environmental impact of the construction?

• disturbances to plant and animal habitats

• decreased water levels behind the dam

• contamination of groundwater resources

• increased temperature due to exhaust gases

The amount of coal burned to produce electricity by a typical coal plant in the United States during a three year period has increased by 30%.

What immediate impact will this increase in the consumption of coal have on the environment?

• a decrease in freshwater resources

• an increase in non-biodegradable wastes

• an increase in greenhouse gas emissions

• a decrease atmospheric O2

Sam reads a survey which states that wood is used by over two billion people to heat homes and cook and process food. He then analyzes the impact of this form of energy on the environment.Which is likely the most significant impact of this form of energy generation?

• It has polluted surface water resources.

• It has made wood resources difficult to replace.

• It is the major cause of the clearing of forest lands.

• It has increased the emissions of greenhouse gases.

Review the diagram.

How does the process shown support water as a renewable resource?

• The water cycle allows water to be used many times.

• The water cycle uses ony a small amount of water.

• The water cycle helps replace water that has been polluted.

• The water cycle creates more water as it is needed.

Scientists have collected data for all the known families of animals, both extinct and living, and graphed those families over time. Mass extinction events are indicated by the letters V, W, X, Y, and Z.

What can be concluded from the graph?

• Between each extinction event there was a significant increase in the number of animals.

• Between each extinction event there was a significant decrease in the number of animals.

• The extinction event at X produced the smallest drop in the number of animals.

• The extinction event at Z produced the greatest drop in the number of animals.
