The oil used today is made from the ancient remains of tiny sea creatures called "diatoms". When they were alive, the diatoms converted sunlight into stored energy. Based on this information, which of the following statements is true?
The sun turned diatoms into oil after 10-20 years.
Diatoms are the original source of energy for oil.
The sun is the original source of energy for oil.
Diatoms converted oil into energy.
Moving water can be used to produce electricity because
most forms of energy can be converted into other forms.
energy cannot be converted into other forms of energy.
potential energy can be converted into kinetic energy, but not vice versa.
kinetic energy can be converted into potential energy, but not vice versa.
Which of these statements about nonrenewable resources is true?
They are inexpensive.
They help keep the air clean.
They can take millions of years to form
They are used because they are easily removed from the ground.
Unlike coal, wind energy is renewable. Wind farms are being used to turn the power of the wind into electricity. What is an advantage of using wind instead of coal to produce electricity?
Wind produces more electricity.
Wind is available in unlimited supply.
Wind farms produce more waste than coal.
Wind farms cost less to run than coal power plants.
Dams are built on rivers to hold back water. The water is then released and passes through turbines to produce
solar energy.
thermal energy.
chemical energy.
electrical energy.
Coal-powered plants are designed specifically to convert
electrical energy to heat energy.
chemical energy to electrical energy.
electrical energy to radiant energy.
kinetic energy to potential energy.
What human actions helps maintain a renewable resource?
building power plants that use coal as fuel
clearing land for roads and buildings
directing fertilizer runoff to ponds
replanting trees in deforested areas
Which of these is the most likely reason scientists are trying to find ways to get energy from more renewable resources?
Renewable resources cost less to produce energy than nonrenewable resources.
Renewable resources are easier to replace than nonrenewable resources.
Renewable resources create more power than nonrenewable resources.
Renewable resources are less dangerous than nonrenewable resources.
Wind is becoming more common as a source of energy. Wind farms require large open spaces for the wind turbines. A negative consequence of this technology is wind turbines
are an inexpensive source of energy.
cause little pollution to the environment.
may hurt the flying animals in the area
are a renewable source of energy.
Using fossil fuels wisely and avoiding waste is an example of
rationing.
recycling.
substitution.
conservation.
Which two behaviors best demonstrate stewardship of resources?
reducing consumption, recycling wastes
increasing consumption, discarding wastes
reducing consumption, discarding wastes
increasing consumption, recycling wastes
The usage of electricity in the United States has increased dramatically over the past 20 years. Most of this electricity is currently produced by burning fossil fuels. What is one reason for this increased usage of electricity?
increase in renewable resources
increase in nonrenewable resources
increase in human population
increase in solar panels
The usage of electricity in the United States has increased dramatically over the past 20 years. Most of this electricity is currently produced by burning fossil fuels. How does this increase in burning fossil fuels impact Earth's climate?
temperatures increase globally and severe weather events increase
temperatures decrease globally and severe weather events increase
temperatures decrease globally and severe weather events decrease
temperatures increase globally and severe weather events decrease
The pie chart below compares the amounts of energy from different sources used in the United States each year. Which two energy sources together provide more than 50% of the energy needs of the United States?
nuclear and natural gas
oil and coal
hydropower and oil
natural gas and coal
City administrators can encourage energy conservation by
lowering parking fees
building larger parking lots
decreasing the cost of gasoline
lowering the cost of bus fares
What is the original source of energy for the fuel in the oil truck?
Earth's interior
The sun
cracks in Earth's crust
dinosaurs
Moving water in a river is considered a renewable resource because it
carries dissolved oxygen
easily erodes sediments
is made of natural gas
can be recycled by nature over time
The diagram shows a power station that makes electricity and impacts the area around it. How might the toxins polluting the stream impact human health and safety?
The organisms living in the stream filter the toxins for the humans.
Humans are able to get the energy for a cheap price.
Humans are not impacted by the toxins.
Humans eat the animals that live in and drink from the stream and in turn ingest the toxins.
The diagram represents the steps necessary to provide electricity to area homes. In a power facility, coal is burned to produce heat energy to boil water. The steam produced is used to power the generator, which produces electricity. Select all of the options these homes could use to reduce the negative impact on human health and safety.
Wind farm replaces coal burning power plant.
Use coal mined from a different state
Extract natural gas from the ground nearby
Power the home with solar panels
The original source of the energy resources on Earth is...
coal
oil
plants
the sun
