Which factors allow the earth to have liquid water?

ANSWER:

The factors that allow earth to have liquid water are the atmospheric pressure and the stable temperature.

EXPLANATION:

The distance of the earth from the sun also helps the temperature to be regulated. This temperature is perfect for existence of water in liquid state. At higher temperatures, all water would evaporate and exist in gaseous state. The same is true for very low temperatures where water cannot exist in liquid form. The presence of gases in the atmosphere also enable water to exist in the liquid form.
