Keine andere Welt, die wir kennen, hat solch gro\u00dfe Wasserfl\u00e4chen und so viel Sauerstoff in ihrer Atmosph\u00e4re vorzuweisen. Soviel wir wissen, ist sie auch die einzige Welt, auf der es Leben gibt. Das macht sie so besonders.<\/p>\n<\/div>\n<p>Wer die Erde von einem Raumschiff oder vom Mond aus betrachtet, sieht einen blauen Planeten, eine wahre Oase im Weltraum. Das liegt daran, dass rund sieben Zehntel der Erdoberfl\u00e4che von Meeren bedeckt sind. Wenn das Wasser durch die Sonne erhitzt wird, nimmt es Gasform an (es wird zu Wasserdampf). K\u00fchlt dieses Gas ab, wandelt es sich wieder in Wassertr\u00f6pfchen um und bildet dabei Wolken und Regen.<\/p>\n<p>Dieser Wasserkreislauf ist m\u00f6glich, weil die Erde 150 Millionen Kilometer von der Sonne entfernt liegt, in der \u2018Goldilocks\u2019-Zone des Sonnensystems. Als dritter Planet von der Sonne aus gesehen ist die Erde weder zu hei\u00df noch zu kalt, als dass Ozeane existieren k\u00f6nnten. Auch die Temperatur ist genau richtig f\u00fcr Leben.
