Humans (biosphere) building a dam out of rock material (geosphere) Water in the lake (hydrosphere) seeps into the cliff walls behind the dam, becoming groundwater (geosphere) or evaporating into the air (atmosphere) Humans (biosphere) harness energy from the water (hydrosphere) by having it spin turbines (geosphere) to produce electricity. Solar energy (exogenous: energy coming from somewhere other than the earth (external) Geothermal energy (endogenous: energy coming from within the earth. The closer you are the earth, the warmer it is (troposphere)
