What are greehouse gases?

Answer 1

Green house gas effect is a phenomenon that takes place in the atmosphere. Have you ever thought why this occur? well the answer is that the greenhouse gases forms a layer in the earths atmosphere. this layer only allows light radiations through it. the suns radiation enters this layer as light radiations.

these light rays are absorbed by the earth on reaching it (remember that earth only absorbs light rays not heat). thus the heat is radiated to the atmosphere.But the greenhouse gas layer forbids this radiation to get out of the earths atmosphere as it is not a light ray anymore. thus the heat is trapped in the earth increasing the earth's temparature. this is greenhouse gas effect. this leads to global warming which further leads to glacier and ice cap depletion.

Answer 2

Greenhouse gases are gases with three or more atoms that are in our atmosphere that tend to absorb or retain energy.

The primary gas is water vapor which accounts for 80 to 90% of the absorption.

Carbon dioxide is second in command and makes up about 0.04% of the atmosphere and 10% of the forcing.

man produces about 0.28% of all greenhouse gases and even when excluding water produces less then 6% of all gases. Nature produces the rest and we would be dead without them.

Answer 3

Greenhouse gases are gases made up of various gases like carbon dioxide, methane, nitrous oxide, HFCs, PFCs and SF6. Greenhouse gases are very bad and are the cause for global warming. They trap the heat from the sun on the earth. Hope this helped.

Answer 4

Any gaseous compound that when present in the atmosphere acts to reflect infra-red light back to Earth rather then allowing to to radiate into space is a greenhouse gas. Examples of such gases are: Water Vapour, Methane and Carbon Dioxide.

Answer 5

Greenhouse gases are gases in the Earth's atmosphere that trap heat from the sun, contributing to the greenhouse effect and warming the planet. Common greenhouse gases include carbon dioxide, methane, nitrous oxide, and water vapor. Human activities, such as burning fossil fuels and deforestation, have increased the concentration of these gases in the atmosphere, leading to global warming and climate change.

Answer 6

gasses such as carbon dioxide which trap the sun's heat causing a green house effect
