Questions and Answers

1.

What would you expect to be the albedo of a sheet of white paper?
- A.
  
  1.0
- B.
  
  0.8
- C.
  
  0.6
- D.
  
  0.4
- E.
  
  0.2
Correct Answer
B. 0.8

Explanation
A sheet of white paper is expected to have a high albedo, which means it reflects a large amount of light that falls on it. The albedo of 0.8 indicates that 80% of the incident light is reflected by the white paper, while only 20% is absorbed or transmitted. This high reflectivity is due to the paper's white color, which reflects most of the visible light spectrum.

If the average temperature on the earth were to increase, what would you expect to happen to the average value of the albedo?
- A.
  
  Increase
- B.
  
  Stay the same
- C.
  
  Decrease
- D.
  
  Cannot say without further information
Correct Answer
C. Decrease

Explanation
If the average temperature on Earth were to increase, it would lead to a decrease in the average value of the albedo. Albedo refers to the measure of how much sunlight is reflected back into space by Earth's surface. When the temperature rises, it causes ice caps, glaciers, and snow to melt, exposing darker surfaces like land and water. These darker surfaces have lower albedo, meaning they absorb more sunlight and reflect less of it back into space. As a result, the average value of the albedo decreases when the average temperature increases.

When radiation first reaches earth from the sun, why is it not absorbed by the greenhouse gasses BEFORE it reaches the earth?
- A.
  
  The temperature in the atmosphere is too low
- B.
  
  The temperature in the atmosphere is too high
- C.
  
  The radiation from the sun consists of radiation mostly with the wrong wavelength
- D.
  
  The radiation comes in through a gap in the ozone layer
Correct Answer
C. The radiation from the sun consists of radiation mostly with the wrong wavelength

Explanation
indeed it is only infrared radiation which is absorbed by the greenhouse gasses - and they do absorb this radiation, but much of the energy from the sun is of a wavelength which is too short to be absorbed by the greenhouse gasses.

Which of the following is NOT greenhouse gas
- A.
  
  Water
- B.
  
  Carbon dioxide
- C.
  
  Nitrous oxide
- D.
  
  Methane
- E.
  
  CFC
Correct Answer
E. CFC

Explanation
CFC, or chlorofluorocarbon, is not a greenhouse gas. While it does have a negative impact on the ozone layer, it does not contribute significantly to the greenhouse effect. Water, carbon dioxide, nitrous oxide, and methane are all greenhouse gases that trap heat in the Earth's atmosphere and contribute to global warming.

What is wrong with the following statement, "The radiation from the sun consists of all parts of the EM spectrum and this passes down through the atmosphere, hits the earth and is reflected in the infrared region only"
6.

What is the molecular process by which the greenhouse gas molecules absorb the infra red radiation?

Correct Answer
resonance
molecular resonance

Explanation
Resonance is the molecular process by which greenhouse gas molecules absorb infrared radiation. This occurs when the energy of the incoming infrared radiation matches the natural vibrational frequency of the gas molecule. The molecule absorbs the energy, causing its bonds to vibrate and store the energy temporarily. This leads to an increase in the molecule's internal energy and temperature, contributing to the greenhouse effect. Molecular resonance refers specifically to the phenomenon of energy absorption and vibration within the molecule.

7.

Explain why only infra red radiation from the earth is absorbed by the greenhouse gases.
8.

Which green house gas in the atmosphere is actually responsible for absorbing the most infra red radiation
- A.
  
  Water
- B.
  
  Carbon dioxide
- C.
  
  Methane
- D.
  
  Nitrous oxide
Correct Answer
A. Water

Explanation
Water vapor is the greenhouse gas responsible for absorbing the most infrared radiation in the atmosphere. This is because water vapor is present in much larger quantities compared to other greenhouse gases like carbon dioxide, methane, and nitrous oxide. Water vapor absorbs and re-emits infrared radiation, trapping heat in the Earth's atmosphere and contributing to the greenhouse effect.
