IV. КРУГООБІГ ВОДИ

Підземні та поверхневі води глибокі і стікають до нижчих рівнів, поки зрештою не досягнуть моря. Зазвичай вони перевантажені мінералами в розчині або суспензії, під час течії як поверхневі води вони можуть штовхати більш важкі скелі по дну потоку. Вся ця чужорідна речовина залишається в морі. В результаті тепла від сонця вода випаровується у водяну пару, яка проноситься повітряними течіями на сотні і тисячі миль, поки хмари не утворюються при конденсації водяної пари         крихітні пилові частинки і порушення викликають осідання ???. Вода, що падає, переходить над землею в море, тим самим повторюючи кругообіг.
