Which of the following is NOT true about greenhouse gases?

• The main ones are Carbon dioxide, water vapour, and methane

• they absorb and re-emit heat energy back to earth

• only molecules with single bonds can be greenhouse gases

• without greenhouse gases, the earth would be much colder

• This is where life exists and weather occurs

• This is where meteors burn up
