Question

3. The greenhouse effect is driven by the fact that greenhouse gases are:

Answer 1

Answer:

Good absorbers of longwave radiation and poor absorbers of shortwave radiation

Explanation:

Gases in the atmosphere such as carbon dioxide, water vapor, methane, nitrous oxide, ozone and some artificial chemicals such as chlorofluorocarbons absorb and re-radiate the sun's energy maintaining the Earth's temperature at around 33 degrees Celcius, this happens especially with infrared light that wants to go back to space, greenhouse gases are good at absorbing and emitting radiant energy within the thermal infrared range (range from about 700nm to 1mm), IR is considered long-wavelength radiation.

Considering this information we can assume greenhouse gases are good absorbers of longwave radiation and poor absorbers of shortwave radiation (such as UV or gamma rays)

I hope you find this information useful and interesting! Good luck!

Answer 2

Answer:

good absorbers of longwave radiation and poor absorbers of shortwave radiation

Explanation:

Greenhouse gases such as carbon dioxide, methane and water vapor are known to be good absorbers of long wave radiations that are emitted from the surface of the earth.

Visible light and ultraviolet radiations are long wave radiations that emanates from the sun. Ultraviolet radiations are cut off by the ozone layers in the atmosphere. Visible lights are able to reach the surface. Some of the energy of light is absorbed while some are emitted in form of long wave infrared radiations. This long wave radiation is easily absorbed by greenhouse gases and it in turn warms the lower fringes of the atmosphere.
