Multiple Choice
Burning fossil fuels releases carbon emissions into the atmosphere. That carbon dioxide traps energy from sunlight.
Which of the following will most likely happen if humans continue to burn fossil fuels for energy?
Polar ice caps will expand, gaining more ice.
Warmer temperatures will increase the food produced on farms.
The sea level will rise, covering cities.
More clouds will form in the atmosphere, cooling Earth.
13
Multiple Select
Which of the following are examples of alternative energy?
Solar
Wind
Hydropower
Nuclear

Match
Match the following
Carbon dioxide emissions from fossil fuels cause climate change.
A graph of carbon dioxide levels throughout history shows that carbon dioxide levels have risen very quickly in the last hundred years. A graph of average global temperature shows that the temperature on Earth has increased very quickly in the last 100 years.
Fossil fuels release carbon dioxide when burned. Carbon dioxide is a greenhouse gas that traps energy from sunlight. As the carbon dioxide in the atmosphere increased, it trapped more energy. Earth's temperature increased due to the extra energy.
