The greenhouse effect is a natural process
true
false
The greenhouse effect is caused by
more heat arriving at the Earth from the sun
the Earth releasing more heat at night
gases in the air trapping heat released by the Earth
Which of the gases is NOT a greenhouse gas?
water vapour
carbon monoxide
carbon dioxide
methane
Which are greenhouse gases? (Select all that apply)
Oxygen
Carbon Dioxide
Nitrogen
Methane
What do greenhouse gases do?
absorb UV light
absorb visible light
absorb infrared radiation
reflect infrared radiation
Which of the following activities contributes the most to carbon emissions globally?
Agriculture
Burning fossil fuels
Respiration
Deforestation
A country's government has been looking for ways to help solve the issue on global warming. Is planting trees one of the best ways to help solve the problem? Why or why not?
Yes, because trees give us shed and protects us from the heat of the sun.
No, because trees only contribute to the carbon dioxide level in the atmosphere.
No, because trees only gives off oxygen as its by products in the
photosynthesis.
Yes, because trees help in absorbing the carbon dioxide, one of the gases that traps the heat in the atmosphere.
What are the important roles of the greenhouse gases?
I. It is necessary for communication.
II. It reflects back the sun’s rays to Earth to keep it cold.
III. It helps the Sun in providing the energy needed by Earth.
IV. It absorbs infrared radiation from the earth and re-radiate it back to the Earth.
IV only
II and IV only
II and III only
I, II and III only
What do greenhouse gases do?
Reflect the sun's energy
Block the sun's infrared radiation
Act as a thermal blanket for the Earth, absorbing heat and warming the surface
They help light up the moon at night
What happens to the light energy from the sun when it hits the Earth's surface? (Select all that apply)
It is absorbed
It is reflected back to space
It is trapped by greenhouse gases in the Earth's atmosphere
If we didn't have the 'greenhouse effect' at all, Earth would
have volcanoes erupting everywhere
Cool to a point where we could not live here
Catch on fire
blow up from being hit by meteors
What is the primary function of the clear glass of the greenhouse?
The glass allows long wavelengths of radiation to enter, but reduces the amount of short wavelength radiation that escapes.
The glass allows short wavelengths of radiation to enter, but reduces the amount of long wavelength radiation that escapes.
The glass allows all wavelengths of radiation to enter and all wavelengths of radiation to escape.
The glass reduces the amount of solar radiation entering the greenhouse.
This significant change in CO2 concentration is most likely caused by
Increased use of fossil fuels, and is predicted to increase average global temperatures
Increased El Niño activity, and is predicted to decrease average global temperatures
decreased cloud cover, and is predicted to decrease average global temperatures
decreased volcanic activity, and is predicted to increase average global temperatures
Deforestation increases the greenhouse effect on Earth because deforestation causes the atmosphere to contain
less carbon dioxide, which absorbs short-wave radiation
less oxygen, which absorbs short-wave radiation
more carbon dioxide, which absorbs infrared radiation
more oxygen, which absorbs infrared radiation
