Methane
The greenhouse effect is:
When the Earth gets very hot.
The gradual increase in surface temperature of the Earth.
When energy from the Sun is transferred into the thermal energy store of gases in the atmosphere.
A very concerning phenomenon.
Global warming is:
When the Earth gets very hot.
The gradual increase in the surface temperature of the Earth.
When energy from the Sun is transferred into the thermal energy store of gases in the atmosphere.
What happens in countries which have hot summers.
What do scientists think will happen due to global warming?
Unpredictable weather will be more frequent.
Ice caps in the Arctic and Antarctic will melt.
Sea levels will rise.
Droughts will affect farming and may cause famine. .
Which of these statements is incorrect?
Methane is a greenhouse gas.
21% of the Earth's atmosphere is oxygen.
The soil is a carbon sink; it absorbs and stores carbon.
An ore is a rock that contains minerals.
What caused the amount of oxygen in the Earth's early atmosphere to increase?
Respiration
Volcanic activity
Photosynthesis
Earthquakes and uplift
What was the major cause of the decrease in carbon dioxide levels in the Earth's early atmosphere?
It was locked up in fossil fuels and sedimentary rocks
Volcanic activity
It formed the oceans with condensed water vapour

Which of the following are direct causes of climate change?
Using nuclear power stations.
Manufacturing plastics from crude oil.
Geothermal energy.
Petrol powered cars.
Why is the ozone layer important?
Absorb harmful UV rays.
Keep the surface of the Earth temperate.
Provides light to the Earth.
Protects the Earth from meteor strikes.
Why are greenhouse gases important?
Absorb harmful UV rays.
Keep the surface of the Earth temperate.
Provides light to the Earth.
Protects the Earth from meteor strikes.
Deforestation leads to the amount of carbon dioxide in the atmosphere...
...increases.
...decreases.
Climate researchers in Greenland can use ice core samples to tell them about methane in the atmosphere in the past. Researchers found a sample that showed a time period when methane in the atmosphere increased. What happened to amount of energy absorbed by Earth's surface during this time?
During this time, the amount of energy absorbed by Earth’s surface
stayed at a constant level.
changed unpredictably.
increased.
decreased.
There are some bacteria that release methane into the atmosphere. Scientists think that if the number of these bacteria decreased, the amount of methane in the atmosphere would decrease.
What would happen to energy in the Earth system if the atmosphere had less methane?Energy in the Earth system would
decrease, because less energy would enter than exit. This is because less exiting energy would beredirected (bounced) back toward Earth.
decrease, because more energy would enter than exit. This is because less exiting energy would beredirected (bounced) back toward Earth.
decrease, because less energy would enter than exit. This is because less energy would be trapped by gases and held in the atmosphere.
increase, because more energy would enter than exit. This is because less energy from the sun would beredirected (bounced) back toward outer space.
Some scientists found that millions of years ago, there was a time when the number of trees increased very quickly, leading to a decrease in the amount of carbon dioxide in the atmosphere. What would you predict about the amount of energy absorbed by Earth's surface during this time?
During this time, the amount of energy absorbed by Earth’s surface
increased.
decreased.
stayed at a consistent level.
changed unpredictably.
Fossil evidence from the time of Tyrannosaurus rex (85–65 million years ago) shows less energy entered the Earth system than exited, even though energy from the sun didn’t change. How might the amount of carbon dioxide changed to cause this, and how would that have changed the energy absorbed by Earth’s surface??
Carbon dioxide decreased so there was less energy in the Earth system and less energy absorbed by Earth's surface.
Carbon dioxide decreased so there was more energy in the Earth system and more energy absorbed by Earth's surface.
Carbon dioxide increased so there was more energy in the Earth system and more energy absorbed by Earth's surface.
Carbon dioxide increased so there was less energy in the Earth system and less energy absorbed by Earth's surface.
Which of the following gases, released by cattle livestock as a waste product of digestion, can add to global warming? Hint: It does the most damage compared to other greenhouse gases.
Carbon Dioxide
Methane
Chlorofluorocarbon
Nitrogen

lower sea levels
a sale on bathing suits
Over the past 200 years, the level of carbon dioxide in the atmosphere has
decreased slightly.
increased until recently, and then decreased.
increased steadily.
stayed about the same.
Which of the following is NOT a greenhouse gas?
Oxygen (O2)
Carbon Dioxide
Methane
Nitrous Oxide
Do we need greenhouse gases on Earth?
Yes - they keep the Earth warm
Yes - they get ride of all harmful gases on our planet
No - they only cause terrible climate change
No - they only block some of the Sun's rays
