Es el \u00fanico mundo que conocemos que cuenta con grandes extensiones de agua en la superficie y una gran cantidad de ox\u00edgeno en su atm\u00f3sfera. Adem\u00e1s, es el \u00fanico mundo conocido en el que existe vida. Esto la convierte en un lugar muy especial.<\/p>\n<\/div>\n<p>Vista desde una nave espacial o desde la Luna, la Tierra se presenta como un planeta azul: un oasis en el espacio. Esto se debe a que aproximadamente siete d\u00e9cimas partes de su superficie est\u00e1n cubiertas por oc\u00e9anos. Cuando el Sol calienta el agua, esta se convierte en gas (lo que se conoce como vapor de agua). Si este gas se enfr\u00eda, vuelve a convertirse en gotitas de agua, formando nubes y lluvia.<\/p>\n<p>Este ciclo del agua es posible gracias a que la Tierra se encuentra a 150 millones de kil\u00f3metros del Sol, en la \u2018zona de Goldilocks\u2019 del Sistema Solar. Al ser el tercer planeta desde el Sol, la Tierra no es ni demasiado caliente ni demasiado fr\u00eda para que existan oc\u00e9anos. La temperatura tambi\u00e9n es la ideal para la vida. Y as\u00ed ha sido durante miles de millones de a\u00f1os.<\/p>","protected":false},"excerpt":{"rendered":"<p>Earth is like no other planet that we have yet observed.
