TRANSCRIPT
Fossil fuels• Fuels that come from
the ground• Burning them
produces energy to heat our homes, run our cars, and produce energy to run factories
• Examples- Oil, Gas and Coal
Burn Fossil Fuels• Produces
Carbon Dioxide (CO2)
(Greenhouse gas)
• Causes Global Warming
• Melts the Ice Caps
The Sun’s energy passes through the car’s windshield.
This energy (heat) is trapped inside the car and cannot pass back through the windshield, causing the inside of the car to warm up.
Example of the Greenhouse Effect
What’s the difference between “global warming” and
“climate change”?
DifferenceGLOBAL WARMING
is the increase of the Earth’s average surface temperature due to a build-up of greenhouse gases in the atmosphere.
CLIMATE CHANGE is a broader term that
refers to long-term changes in climate, including average temperature and precipitation.
Effects of Global WarmingIncreased Temperature
