1.the hot interior of the earth, let the temperature __1__of the sun.As we know, life would only be possible on the face of a __2__planet had temperatures somewhere within this range. __3__The earth’s supply of water probably remains quite fairly constant __4__in quantity. A certain number of hydrogen atoms, whichare one of the main constituents of water, are lost by escapingfrom the atmosphere to out space, but they are probably just __5__about to be replaced by new water rising away from the depths of the __6__earth during volcanic action. The total quantity of water is notknown, and it is about enough to cover the surface of the globe __7__to a depth of about two and three-quarter kms. Most of it—97%is in the form of the salt waters of the oceans. The rest isfresh, but three quarter of this is in the form of ice at the Poles __8__and on mountains, and cannot be used by living systems when __9__melted.
