Geosphere is a collective name for the lithosphere, hydrosphere, cryosphere and atmosphere. The different aspects of the geosphere are able to exchange mass and/or energy fluxes (the measurable amount of change). The exchange of these fluxes affects the balance of the different spheres. — Wikipedia




Earth System Science (ESS) is the application of systems science to the Earth.In particular, it considers interactions and ‘feedbacks’, through material and energy fluxes, between the Earth’s sub-systems’ cycles, processes and “spheres”—atmosphere, hydrosphere, cryosphere, geosphere, pedosphere, lithosphere, biosphere, and even the magnetosphere. — Wikipedia

Physiography, also known as physical geography, is a branch of science which deals with the processes and patterns in the natural environment such as the atmosphere, hydrosphere and lithosphere. — Wikipedia
