In the series, we gather phenomena and processes that illustrate the intertwining and fundamentally unified view of physics, biology and geography. The first article explained the soil physics, the second one the physical and chemical properties of water, the third the physics of oceans, seas, the fourth the physics of lakes and the fifth the rivers. In this article, we discuss the characteristics and processes of deep waters and their explanation.}, }
