The earth system is made up of many spheres. these spheres interact. imagine humans, part of the biosphere, have built this dam. the water in the lake behind the dam seeps in the ground. some of the water flows over the dam and is converted into energy. some water evaporates into the air. what spheres does the water, or hydrosphere, interact with in this example?
