Easy Quiz 1 On Global Warming

1. The Global Warming that is happening now is ...

A natural cycle of the earth's climate

Mostly caused by human activity

Caused by the damaged ozone layer

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).

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).

2. Which one of these is an important greenhouse gas?

Oxygen

Hydrogen

Nitrogen

Carbon Dioxide

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.

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. 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 ...

Wood chips

Coal

Biomass

Peat

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.

4. 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 ...

The greenhouse effect temperature is about the same

The greenhouse effect is cooling

The greenhouse effect is warmer than it should be

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.

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.

5. How do we contribute to global warming when we burn fossil fuel like oil or coal?

We release ozone emissions

We release chlorofluorocarbon emissions

We release carbon dioxide emissions

We release sodium chloride emissions

We release carbon monoxide emissions

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.

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.

6. What gas do trees and other green plants remove from the atmosphere (through photosynthesis)?

Carbon dioxide

CFCs (chlorofluorocarbons)

Oxygen

Ozone

Carbon Monoxide

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.

7. Which one of these is a fossil fuel?

Hydrogen

Biofuel

Wind Power

Petroleum

Wood

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.

8. The Natural Greenhouse Effect in the atmosphere is ...

A good thing for the earth

A dangerous effect that we don't need

Kept warm by the ozone layer

Not happening. It doesn't exist!

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.

9. Which of the items below contribute to global warming?

Riding a bicycle

Breathing out carbon dioxide

Planting a tree in your garden

Driving in an old car with three other people

Turning off a computer at the wall socket

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.

10. What is the BEST thing (out of the list below) that we, and everyone in the world, should do about Global warming?

Start using renewable energy like solar and wind to make electricity

Recycle paper, plastic, glass and aluminum cans

Walk or ride a bicycle instead of riding in a car

Turn off the lights in your house when nobody is there

Buy some chickens or a worm farm to stop putting food into the garbage bin

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.
