C\u2019est le seul monde que nous connaissons qui poss\u00e8de de vastes \u00e9tendues d\u2019eau \u00e0 sa surface et une atmosph\u00e8re riche en oxyg\u00e8ne. C\u2019est \u00e9galement le seul monde connu pour abriter la vie. Cela en fait un monde tout \u00e0 fait exceptionnel.<\/p>\n<\/div>\n<p>Vue depuis un vaisseau spatial ou depuis la Lune, la Terre appara\u00eet comme une plan\u00e8te bleue \u2013 une oasis dans l'espace. Cela s'explique par le fait qu'environ sept dixi\u00e8mes de sa surface sont recouverts d'oc\u00e9ans. Lorsque l'eau est chauff\u00e9e par le Soleil, elle se transforme en gaz (appel\u00e9 \u00ab vapeur d'eau \u00bb). Si ce gaz se refroidit, il redevient des gouttelettes d\u2019eau, formant ainsi des nuages et de la pluie.<\/p>\n<p>Ce cycle de l'eau est rendu possible par le fait que la Terre se trouve \u00e0 150 millions de km du Soleil, dans la \u2018 zone Goldilocks \u2019 du syst\u00e8me solaire. En tant que troisi\u00e8me plan\u00e8te \u00e0 partir du Soleil, la Terre n'est ni trop chaude ni trop froide pour permettre l'existence d'oc\u00e9ans. La temp\u00e9rature y est \u00e9galement id\u00e9ale pour la vie. Et cela dure depuis des milliards d'ann\u00e9es.<\/p>","protected":false},"excerpt":{"rendered":"<p>Earth is like no other planet that we have yet observed.
