Dette skyldes at omtrent syv tideler av overflaten er dekket av hav. N\u00e5r vannet varmes opp av Solen, forvandles det til en gass (kjent som vanndamp). Hvis denne gassen avkj\u00f8les, blir den igjen til vanndr\u00e5per som danner skyer og regn.<\/p>\n<p>Denne vannkretsl\u00f8pet er mulig fordi Jorden ligger 150 millioner km fra Solen, i solsystemets \u2018Goldilocks\u2019-sone. Som den tredje planeten regnet fra Solen er Jorden verken for varm eller for kald til at det kan finnes hav her. Temperaturen er ogs\u00e5 akkurat passe for liv.
