Answer:
The four spheres of Earth drive all of its processes and support life on our unique planet. In this video lesson, you will see examples of how Earth's spheres interact with each other to form an overall complex and connected system.
Earth's Spheres Interact
In another lesson, we learned about Earth's four spheres. These are the geosphere, hydrosphere, biosphere and atmosphere. Together, they make up all of the components of our planet, both living and non-living. And while we can describe each individually in terms of its properties and features, you'd have a difficult time finding an example where one sphere doesn't either touch or interact with at least one other.
This is important because these interactions are what drive Earth's processes. Material on Earth doesn't stay how it is. It gets recycled into other phases and forms. Plants in the ground die, and as they are broken down by microorganisms, they become soil, which can then feed new plants. Water cycles through different phases and locations, like when it evaporates from the oceans and then rains down onto the ground or into a lake. Rock also gets recycled under Earth's surface, where it is melted down and then sent back up in volcanic eruptions.
