Земля . Обилие жидкой воды на поверхности и кислорода в атмосфере - вот, пожалуй, основные отличия Земли от всех известных на сегодняшний день небесных тел. Если земная атмосфера представляется из космоса тонкой и прозрачной, и если бы не облака, она выглядела бы совсем жалко, то занимающие около 70% поверхности океаны выглядят впечатляюще. Средняя глубина этой полноправной оболочки - гидросферы - примерно 4 км, и она представляет собой не просто заполненные водой впадины. ...
