Greenhouse gas

A gas in the atmosphere that absorbs long-wavelength infrared radiation emitted by Earth and re-emits it in different directions.

A gas in the atmosphere that absorbs long-wavelength infrared radiation emitted by the Earth and transfers energy to its surroundings.

A gas that absorbs infrared radiation emitted by Earth and transfers energy to the surroundings, warming the atmosphere.

A gas that absorbs heat radiated from Earth and releases energy, helping to keep the planet warm.

An atmospheric gas that absorbs and re-emits infrared radiation, such as carbon dioxide, water vapour or methane.

A gas, such as carbon dioxide or methane, that absorbs infrared radiation emitted by the Earth and contributes to the greenhouse effect.

An atmospheric gas whose molecules absorb and emit infrared radiation at particular wavelengths; examples include carbon dioxide, water vapour and methane.

A gas in the atmosphere that absorbs infrared radiation emitted by the Earth and re-emits it in all directions, helping to warm the surface and lower atmosphere.
