Dr Jens Kleb thank you for your contribution to the discussion

When it evaporates, the surroundings are cooled; as it condenses, water releases energy and warms its surroundings. Water sculpts landforms through erosion and the movement of minerals; it hydrates life on the planet, and plays a role in the transfer of energy from terrestrial to aquatic systems. Water moves through the hydrosphere in a cycle. Water collects in clouds, then falls to Earth in the form of rain or snow. This water collects in rivers, lakes and oceans. Then it evaporates into the atmosphere to start the cycle all over again. The geosphere subsystem significantly affects the flow of matter and energy on Earth by contributing to the formation of fossil fuels, regulating nutrient cycling, driving plate tectonics, forming soils, providing heat energy, and storing and filtering water. Driven by solar energy, surface waters evaporate into the atmosphere, condense, and fall back to the surface as precipitation, shaping continents, creating rivers, and filling lakes. This process has eroded billions of tons of surface material from the continents to the oceans, forming the major river deltas. The biosphere benefits from this food web. The remains of dead plants and animals release nutrients into the soil and ocean. These nutrients are reabsorbed by growing plants. This exchange of food and energy makes the biosphere a self-supporting and self-regulating system. Once received by radiation or convection thermal energy is distributed through the atmosphere and the hydrosphere by convection and conduction. Dead producers and consumers and their waste products provide matter and energy to decomposers. Decomposers transform matter back into inorganic forms that can be recycled within the ecosystem. So, the energy that enters an ecosystem as sunlight eventually flows out of the ecosystem in the form of heat. The atmosphere brings back rainwater to the hydrosphere. In what way do the geosphere and hydrosphere connect? Water provides the moisture and medium for weathering and erosion of rocks in the geosphere. The geosphere, in turn, provides the platform for ice melts and water bodies to flow back into the oceans. The main matter-cycling systems involve important nutrients such as water, carbon, nitrogen and phosphorus. There are many ways in which the energy, water, and biogeochemical cycles (cycles of the elements that involve life, chemicals, and the solid Earth) interact and influence the Earth System.
