2 very low is the correct answer.
- In absence of air on Earth, the temperature would fall in negative.
- This is because, the greenhouse gases present on Earth act as thermal blanket of the planet.
- They do so by trapping the radiation and hence heat on the planet, maintaining its temperature.
- The greenhouse gases are carbon dioxide, water vapour and methane.
