A la izquierda<\/strong>, en forma de esfera, se representa todo el agua del mundo, esto es, la hidrosfera, incluyendo el agua de los oc\u00e9anos, hielo, lagos, r\u00edos, aguas subterr\u00e1neas o la presente en las nubes. La masa total de la hidrosfera supone 1,4\u00d71021<\/sup> kg.<\/p>\n

A la derecha<\/strong>, una esfera que muestra todo el aire de la atm\u00f3sfera, considerando una densidad uniforme medida a nivel del mar. La masa total de la atm\u00f3sfera es de 5,1\u00d71018<\/sup> kg.<\/p>\n

Las dos representaciones se muestran en relaci\u00f3n con el volumen del planeta Tierra.<\/p>\n
