stop relying on wiki for your homework questions. cuz ppl lyke meh do stufffz lyke tht.
They slow the loss of heat
Greenhouse gases are very light but they change how sunlight is reflected back out into space in that greenhouse gases do not allow as much sunlight to be reflected. This increases the amount of energy held within the atmosphere and warms the planet
About 50% is absorbed by Earth's surface, about 25% is reflected by clouds, dust, and gases in the atmosphere, about 20% is absorbed by gases and particles in the atmosphere and about 5% is reflected by the surface back into the atmosphere. Also some absorbed energy is radiated back into the atmosphere.
The atmosphere exchanges gases by means of convection, radiation, and conduction. This is how energy is transferred between the Earth and the atmosphere.
There are several factors that contribute to the decrease in the amount of energy reaching earth's surface. These are: reflection, scattering, absorption by gases and aerosols in the atmosphere, and cloud cover.
NONE
Greenhouse gases affect the temperature of the atmosphere. They capture the sun's heat and warm the planet.

In the atmosphere
Gases absorb radiation and some is absorbed in the atmosphere :)

the atmosphere is made up of different gases (nitrogen, oxygen, argon, carbondioxide, water vapour and other noble gases). the atmosphere helps to keep the earth warm and at the correct temperature. However if the levels of these gases increase to a huge amount, it will becomes too hot which is one of the signs of global warming!
tit
No. Greenhouse gases in the atmosphere capture heat, and heat is energy, but we have no way of using this energy for ourselves as fuel. This extra energy in the atmosphere will be expended in more severe weather, like storms and cyclones.
