Energy and Mineral Resources > Concept #4 Quiz
More than 85% of the energy used in the U.S.A. is from nonrenewable resources.
Present estimates indicate that the population explosion will result in an increasing depletion of the fossil fuel reserves.
The environmental impact of burning huge quantities of fossil fuels will have an adverse effect on the atmosphere.
Using increased amounts of fossil fuels to meet increasing demand will be stable for many centuries.
Match the type of alternate energy source with the appropriate description:
Using the pulldown boxes, match each item on the left to the corresponding item at right.
Match the type of alternate energy source with its drawbacks and problems in its use:
there are real hazards associated with the disposal of nuclear waste
nuclear power is a clean, cheap source of energy to replace fossil fuels
skyrocketing costs of building nuclear facilities that have to maintain the highest safety standards
possible escape of radioactive debris during a meltdown of the core or other malfunction
Choose the best location for obtaining alternate energy sources:
For each item below, use the pull-down menu to select the letter that labels the correct part of the image.
passive collectors heat objects in a room, whereas active collectors transfer heat to circulating air or fluids
passive collectors transfer heat to circulating air or fluids, whereas active collectors heat objects in a room
passive collectors are roof-mounted boxes, whereas active collectors are south-facing windows
passive collectors use south-facing windows, whereas active collectors are roof-mounted boxes
debris and rocks are deposited on the downstream side of the dam, thus making the power of the impounded water lowered
water volume usually decreases over time due to significant cracks in the dam
sediment is deposited on the upstream side of the dam, thus making the impounded water a lower volume
dams are usually not well built, so they will collapse, usually within a few years of construction
