Science Midterm Test Review

Based on the chart on the right, which energy group is used to produce the most electricity?

• Renewable resources

• Nonrenewable resources

• Liquid energy sources

• Solid energy sources

Coal, petroleum, and natural gas are fossil fuels. They are called fossil fuels because:

• They are burned to release energy and they cause air pollution

• They were formed from the buried remains of plants and tiny animals that lived hundreds of millions of years ago

• They are nonrenewable and will run out

• They are mixed with fossils to provide energy

In the United States, fossil fuels are our main energy source; however, this use has a negative impact on the environment. Which answer below best describes how fossils fuels affect the environment?

• They increase oxygen levels

• They reflect the sun's rays

• They decrease smog

• They increase pollution

Compare the electricity consumption of petroleum to the electricity consumption of all other energy sources in the bar graph above. Over the next 100 years, how do you predict the ratios will change?

• Coal dependence will increase because it is a renewable resource

• Nothing will change because our dependence on fossil fuels will remain the same

• We will depend more on other nonrenewable resources such as: oil or natural gas because they will not run out

• We will depend more on other renewable resources such as: wind or solar energy because they will not run out

A Georgia shoe factory relies heavily on the use of fossil fuels. The owner of the factory wishes to make his company more environmentally friendly by increasing the use of renewable resources, however, he is uncertain as to which resources to use. What question should the owner ask first to determine which alternative resource should be best to use in his factory?

• What alternative resources are the cheapest?

• How can the use of fossil fuels save his company money?

• Which renewable resources are most readily available in Georgia?

• Is nuclear energy too unreliable and unsafe to be used in his factory?

Students in Earth science class are asked to develop and present an argument to their peers as to why carpooling is good for the environment. The student's general ideas for their arguments are presented below. Which student's argument is best supported by available research?

• Student 1: Carpooling saves time and decreases then umber of car accidents

• Student 2: Carpooling saves on gas and parking fees

• Student 3: Carpooling saves on gas and puts less greenhouse gases into the air

• Student 4: Carpooling saves gas and doesn't contribute to Global Warming
