Hydrosphere is the most ancient part of biosphere the further development of which is directed to the settling of aerial surroundings and lithosphere cover by organisms.

Each period is accompanied by respective trend of soil formation, for example hydrozemic period corresponds with underwater soil formation and atmozemic and lithozemic ones to swamp and land respectively.
