Answer:
Earth has four 'spheres,' called the geosphere, hydrosphere, biosphere and atmosphere. These spheres each have unique properties and features, but they are not isolated on Earth, and they work together to drive the processes of the planet. ... These interactions are essential to life on Earth Interactions also occur among the spheres. For example, a change in the atmosphere can cause a change in the hydrosphere, and vice versa. ... Water in the lake (hydrosphere) seeps into the cliff walls behind the dam, becoming groundwater (lithosphere), or evaporating into the air (atmosphere).
Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water),
"biosphere" (living things), and "atmosphere" (air). ese spheres are closely connected. For example, many birds (biosphere) fly through the air (atmosphere), while water (hydrosphere) often flows through the soil (lithosphere). In fact, the spheres are so closely connected that a change in one sphere often results in a change in one or more of the other spheres
