What is the greenhouse effect?

Answer 1

The greenhouse effect is the earth's atmosphere trapping the suns rays and heat. With the depletion of the ozone layers which helps to block UV rays, more UV rays are let in therefor heating up the earth.

Answer 2

The greenhouse effect, first discovered by Joseph Fourier in 1824, and first investigated quantitatively by Svante Arrhenius in 1896, is the process in which the absorption of infrared radiation by an atmosphere warms a planet. The name comes from an incorrect analogy with the way in which greenhouses are heated by the sun in order to facilitate plant growth. In addition to the Earth, Mars, Venus and other celestial bodies with atmospheres (such as Titan) have greenhouse effects.

In common parlance, the term greenhouse effect may be used to refer either to the natural greenhouse effect, due to naturally occuring greenhouse gases, or to the enhanced (anthropogenic) greenhouse effect, which results from gases emitted as a result of human activities (see also global warming, scientific opinion on climate change and attribution of recent climate change)............

Answer 3

The greenhouse effect is when the harmful rays from the sun get into the earths atmosphere through the hole in the o-zone layer and they cannot escape thus heating the earth up. The gaseous layers of the o-zone layer act as a green house would and so reflect the rays back to earth instead of letting them pass through.

Answer 4

simple answer is that in a typical greenhouse, the light comming
IN through a sheet of glass, CHANGES its frequency, once it
hits an object, and once it changes its frequency, it cant get back
OUT through that same sheet of glass.
If radiation from the sun goes through the earths atmosphere,
and there is a layer of stuff that acts like glass, then the radiation
changes frequency, which is normal, but it cant escape, and just
bounces around in the lower areas nearer the ground, getting
hotter and hotter.

Answer 5

Light enters through the glass and part of the energy is absorbed by the various object inside including the air. Some of that energy is re-radiated at a lower frequency. One of the frequency re-radiated is infra-red (i.e. heat). Infra-red can not pass through the glass causing the inside of the greenhouse to rise in temperature.
Glass windows only permit a window (pun intended) of frequencies to pass through. Both the higher and lower frequencies are blocked.

Answer 6

The rise in temperature that the earth expierences because certain gasses in the atmosphere trap energy from the sun.

Answer 7

When heat from sunlight penetrates the atmosphere and can't get back out, thus heating the earth.

Answer 8

i think its carbon burned up, creates carbon dioxide which hangs in the atmosphere, traps heat in the air, world gets hot. like a green house with a glass roof that traps heat inside.

Answer 9

better than the White House effect...
