Questions and Answers

1.

The Global Warming that is happening now is ...
- A.
  
  A natural cycle of the earth's climate
- B.
  
  Mostly caused by human activity
- C.
  
  Caused by the damaged ozone layer
Correct Answer
B. Mostly caused by human activity

Explanation
Climate scientists conclude that it is EXTREMELY LIKELY that global warming is being caused by the human activities of the burning of fossil fuels (coal, oil and natural gas) and deforestation (cutting down trees which previously removed carbon dioxide (CO2) from the atmosphere).

Rate this question:
2.

Which one of these is an important greenhouse gas?
- A.
  
  Oxygen
- B.
  
  Hydrogen
- C.
  
  Nitrogen
- D.
  
  Carbon Dioxide
Correct Answer
D. Carbon Dioxide

Explanation
A greenhouse gas traps heat rising from the surface of the earth. Carbon dioxide (CO2) is the important greenhouse gas that we are adding to the atmosphere.

3.

The Natural Greenhouse Effect in the atmosphere is ...
- A.
  
  A good thing for the earth
- B.
  
  A dangerous effect that we don't need
- C.
  
  Kept warm by the ozone layer
- D.
  
  Not happening. It doesn't exist!
Correct Answer
A. A good thing for the earth

Explanation
The natural greenhouse effect has kept the earth warm enough for life for millions of years. It is a good thing for the earth! If we keep adding EXTRA greenhouse gases to it it causes global warming.

Rate this question:
4.

Which one of these is a fossil fuel?
- A.
  
  Hydrogen
- B.
  
  Biofuel
- C.
  
  Wind Power
- D.
  
  Petroleum
- E.
  
  Wood
Correct Answer
D. Petroleum

Explanation
Fossil fuels are coal, oil and natural gas and similar hydrocarbon products that began life as organic matter hundreds of millions of years ago. We began to dig them up and burn them around 1750. Burning them releases carbon dioxide which is a greenhouse gas.

Rate this question:
5.

How do we contribute to global warming when we burn fossil fuel like oil or coal?
- A.
  
  We release ozone emissions
- B.
  
  We release chlorofluorocarbon emissions
- C.
  
  We release carbon dioxide emissions
- D.
  
  We release sodium chloride emissions
- E.
  
  We release carbon monoxide emissions
Correct Answer
C. We release carbon dioxide emissions

Explanation
Burning fossil fuel like gasoline emits carbon dioxide. Carbon dioxide is a greenhouse gas that is building up in the atmosphere and causing global warming.

Rate this question:
6.

We are putting too much greenhouse gas into the atmosphere. This is changing the greenhouse effect, so that we now call it an enhanced or accelerated greenhouse effect. This means that ...
- A.
  
  The greenhouse effect temperature is about the same
- B.
  
  The greenhouse effect is cooling
- C.
  
  The greenhouse effect is warmer than it should be
Correct Answer
C. The greenhouse effect is warmer than it should be

Explanation
The greenhouse effect we have on earth is an enhanced (or accelerated) greenhouse effect. This is making the earth warmer and is causing global warming.

Rate this question:
7.

What gas do trees and other green plants remove from the atmosphere (through photosynthesis)?
- A.
  
  Carbon dioxide
- B.
  
  CFCs (chlorofluorocarbons)
- C.
  
  Oxygen
- D.
  
  Ozone
- E.
  
  Carbon Monoxide
Correct Answer
A. Carbon dioxide

Explanation
Green vegetation, through the process of photosynthesis, takes carbon dioxide from the atmosphere, releases the oxygen, and stores the carbon, sometimes for hundreds of years, in the case of a tree, until the tree dies.

Rate this question:
8.

Most electricity is generated round the world by power stations. These power stations use steam to turn turbines to produce the electricity. To get the steam they mostly burn ...
- A.
  
  Wood chips
- B.
  
  Coal
- C.
  
  Biomass
- D.
  
  Peat
Correct Answer
B. Coal

Explanation
Most power stations round the world burn coal to generate electricity. Other fossil fuels that are used are oil and natural gas. Fossil fuels release carbon dioxide emissions that add to the greenhouse gases in the atmosphere.

Rate this question:
9.

Which of the items below contribute to global warming?
- A.
  
  Riding a bicycle
- B.
  
  Breathing out carbon dioxide
- C.
  
  Planting a tree in your garden
- D.
  
  Driving in an old car with three other people
- E.
  
  Turning off a computer at the wall socket
Correct Answer
D. Driving in an old car with three other people

Explanation
Driving in an old car burns petrol, or gasoline, which is a fossil fuel with carbon dioxide emissions. Breathing out carbon dioxide releases carbon that came out of the air very recently. It's not the same as fossil fuel carbon, that has been hidden away for millions of years.

Rate this question:
10.

What is the BEST thing (out of the list below) that we, and everyone in the world, should do about Global warming?
- A.
  
  Start using renewable energy like solar and wind to make electricity
- B.
  
  Recycle paper, plastic, glass and aluminum cans
- C.
  
  Walk or ride a bicycle instead of riding in a car
- D.
  
  Turn off the lights in your house when nobody is there
- E.
  
  Buy some chickens or a worm farm to stop putting food into the garbage bin
Correct Answer
A. Start using renewable energy like solar and wind to make electricity

Explanation
All these things are good for everyone to do, but the BEST and most effective way to stop global warming is for the whole world to move to RENEWABLE ENERGY, (solar, wind, water, hydro, tidal and wave, geothermal, ocean thermal, biomass and biofuel) which releases NO greenhouse gases. Then we can stop burning fossil fuels (coal, oil and natural gas) to make our electricity.
