1st SEMESTER FINAL REVIEW

Which of the following is considered a renewable resource?

• nuclear because uranium is easily found and replaced

• coal because once it's used it will take millions of years to form

• biomass because it is replaced at a faster rate than it is used

• natural gas because it can be replaced in a person's lifetime

If a family is trying to find an alternative to using fossil fuels to produce electricity for their home, which of the following could they use for their choice?

• using nuclear power because it will never run out

• using natural gas because it is a cheap energy source

• burning coal in a fireplace because it is a safer source of energy

• installing solar panels on their house to gather sunlight because it is clean energy

A car company claims the electricity they use is generated only by the use of renewable resources. A recent visit to their factory reveals that it uses solar panels and gasoline-powered generators to charge the robot batteries. Which of the following is the BEST reason why we can argue against this claim?

• Solar energy is renewable. Therefore, the company can claim it uses only renewable resources to generate electricity.

• Electricity can only be generated using nonrenewable resources. Therefore, the company cannot claim it uses only renewable resources.

• Gasoline is made from a nonrenewable resource. Therefore, the company cannot claim it uses only renewable resources to generate electricity.

• Electricity can only be generated using renewable resources. Therefore, the company cannot be producing electricity if it uses gasoline-powered generators

Which of the following is a disadvantage of biomass?

• It releases greenhouse gases into the atmosphere.

• Biomass will not be replaced in your lifetime

• It does not release greenhouse gases into the atmosphere.

• It is a nonrenewable resource.

Schools require large amounts of energy to meet students' learning needs, but there are ways schools can reduce energy use without affecting students. Which idea will reduce a school's energy usage the most and have the least effect on students?

• Replace classroom computers with encyclopedia sets for doing research, and replace SMARTboards with dry-erase whiteboards.

• Cafeteria can cook students' lunch meals outside on charcoal grills, instead of inside with the electric stovetops and ovens.

• Remove half of the lightbulbs in each classroom and allow students to bring battery-powered flashlights to use for reading.

• While the school is closed for holiday breaks, central heat/air systems are turned off and electrical items in classrooms should be unplugged

What type of energy resources is likely being used if they are adding greenhouse gases to the atmosphere?

• Fossil fuels because they add carbon dioxide to the atmosphere

• Fossil fuels because they produce heat when they are burned

• Renewable energy because they add carbon dioxide to the atmosphere

• Renewable energy because they produce heat when they are burned

In the last century, Earth’s global temperatures have gradually increased. This phenomenon is called global warming. While there are many contributing factors to global warming, what do scientists hypothesize to be the main cause of global warming?

• Humans are strip mining for coal causing an increase in temperature.

• We are raising cows that belch methane into the atmosphere increasing Earth’s temperature.

• Humans are burning fossil fuels creating excess carbon dioxide which is trapped in the atmosphere and increases Earth’s temperature.

• Deforestation causes carbon dioxide in the trees to be released into the atmosphere which increases Earth’s temperature.
