A group of compounds that are able to trap heat in the atmosphere, keeping the Earth's surface warmer than it would be if they were not present.
CO2 emissions
greenhouse gases
climate change
Global warming is the term used to describe the RISING of the average temperature on Earth.
True
False
Global warming has negative effects on plants, animals and human beings.
True
False
Global Warming is MAINLY caused by...
...the Sun
...the Greenhouse Effect.
The Greenhouse Effect happens when the HEAT cannot escape the Earth.
True
False
Oil and gas produce huge clouds of Carbon Dioxide into the atmosphere.
True
False
Deforestation is another cause of global warming.
True
False
Trees help the Earth because...
...they absorb huge amounts of Carbon Dioxide (CO2) from the air and release oxygen back into it.
...they absorb huge amounts of oxygen from the air and release Carbon Dioxide (CO2) back into it.
Due to a DECREASE in the number of trees and forests, the Carbon Dioxide (CO2) remains in the atmosphere :(
True
False
Recycling, saving energy and using bicycles instead of cars can help reduce Global Warming.
True

D. Methane
Some kinds of pollution in the atmosphere can act to cool the planet by reducing the amount of solar radiation that reaches Earth's surface.
reducing the amount of solar radiation
increasing the amount of solar radiation
reducing the amount of carbon dioxide
increasing the amount of carbon dioxide
Earth has recorded _______________ temperatures in the past than it is today.
warmer
cooler

Global Warming
How can Global Warming cause sea levels to rise?
by causing it to rain more often.
by creating bigger and more powerful hurricanes.
by melting glaciers and ice caps.
by increasing the number of undersea volcanic eruptions.
Why does cutting down trees increase Global Warming?
Trees absorb the Sun’s energy without radiating back into the atmosphere.
Trees drain Greenhouse gases like methane from soil.
Trees provide shade which counteracts Global Warming.
Trees soak up Carbon dioxide.
Why is the increase of Greenhouse gasses a big issue?
It causes climate change and increase in the Global temperature.
It can lead to a major increase in Greenhouses.
It causes a major decrease in people.
It leads to more factories.
How are Greenhouse gasses harming our environment?
Less heat is able to escape causing the Earth to cool down.
Less heat is able to escape causing the Earth to warm up.
More heat is able to escape.
They aren’t.
Things you can do to help decrease Global Warming include:
Keep your air conditioner on high.
Keep your deep freezer door open.
Eat more ice cream.
Turn off your lights when you’re not using them.
In a warmer world, we would expect more...
Hurricanes
Droughts
Desert expansions
All of these
Which of the following are effects of ozone depletion?

All of these.
Burning fossil fuels is one of the main causes for Global Warming.
True
False
All of the following are Greenhouse gasses except...
Nitrogen
Nitrous oxide
Carbon dioxide
Water vapour
Which statement is the most accurate?
Climate is determined by average weather conditions.
Climatologists examine data from one to a few years to estimate weather.
Weather is determined by average climate conditions.
None of these answers are accurate.
Increased levels of Carbon dioxide in the atmosphere have been implicated in which of the following?

The threat of Global Warming can be addressed by...
Slowing population growth.
Reducing deforestation.
Shifting to renewable resources.
Using energy more efficiently.
The main human activity that releases greenhouse gases is...
using bottled water
eating meat
burning fossil fuels
texting on cellphones
The gradual increase in the temperature of the atmosphere is known as
Global Warming

How is the greenhouse effect produced?
When the Sun doesn’t emit radiation.
When some energy is reflected back to Earth.
When solar energy trespasses the atmosphere.
When the greenhouse is burned.
How is the greenhouse effect produced?
