Resumo

This paper deals with the Hydrologie Cycle, a vital element for the Earth as a whole, and especially for life, climatic conditions and the planet's dynamic equilibrium, presenting it, based on the fundamental concepts of Thermodynamics and on the new knowledge and discoveries of geosciences, under two distinct foci: 1) As a Closed System, in the form in which it is currently conceived; 2) As an Open System, in the form in which this article proposes it be understood.
