what is greenhouse effect ?what is it also refered as?

Answer 1

Global warming.

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 emission of infrared radiation by an atmosphere warms a planet's surface. In the case of the Earth, without these greenhouse gases its surface would be up to 30°C cooler. 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 occurring 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).

it is also called global warming

Answer 4

It's called the greenhouse effect because certain gasses (CO2 for one..) trap heat much the way a green house would. Another good example, your car on a hot day..sunlight comes in, strikes surfaces and is converted to heat energy but can't escape..even on a cold sunny day it's warm in your car. Greenhouse effect has always been around, but it can be intensified by our releasing more CO2 than has historically been present in the atmosphere.

Do not confuse this with depletion of the ozone layer, it is caused by pollution of other gases, aerosols, refrigerants, many of these were banned as soon as it's effects were discovered. It is a problem we have, but it's a separate problem altogether.

Answer 5

The greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere (water vapor, carbon dioxide, nitrous oxide, and methane, for example) trap energy from the sun. Without these gases, heat would escape back into space and Earth’s average temperature would be about 60ºF colder. Because of how they warm our world, these gases are referred to as greenhouse gases. global warming is one thing, but i dont think greenhouse effect is also called that.

Answer 6

greenhouse effect:
An enclosure of glass (generally) are constructed to maintain (raise) the temperature within specially for the plants to protect them from the low temperature outside. The effect of raising temperature within the enclosure (green house) is called greenhouse effect.

The same thing applies to our earth (consider plant) and her atmosphere (glass enclosure). In the earlier case the glass and here the atmosphere allow the radiations from the Sun to enter into but stop its reflection. The incoming radiations are of shorter wavelengths penetrates the atmosphere but when it hit an object the reflecting longer wavelengths (Infra red band) which is basically the heat radiation. Thus the ambient temperature raises.

This is a normal and natural phenomena. But when the greenhouse affect is explained in terms of atmospheric pollution, it is referred as Global Warming, because there are certain atmospheric components i.e. CO2, CH4 and H2O, whose increased concentration further restrict the outgoing reflections.

Answer 7

The greenhouse effect is where the light from the sun is refracted and magnified, keeping the earth warm. But all the pollutants in the atmosphere magnify the heat and rays so much, that skin cancer, global warming, and so much more is killing our earth. Regardless of the cause *ahem. global oil industries, atom bombs, bush* we need to find an answer and solution.


P.S. Global warming is not the GE, it is a consequence.

Answer 8

global warming for one, it burns up and create holes in the ozone. ozone filter out harmful radiation from the sun and it's why more people getting skin cancer and have to use sun block with high spf.
