Free 5-day trial The four spheres of Earth drive all of its processes and support life on our unique planet.

In another lesson, we learned about Earth's four spheres.

These are the geosphere, hydrosphere, biosphere and atmosphere.

And in the geosphere, their roots help keep the ground in place, protecting it from wind and rain.

As you can see, it's really difficult to tease apart where one sphere ends and another begins.

Not only do each of the spheres constantly interact with the others, but it can often be difficult to tell exactly where one sphere ends and another begins.This is important because these interactions are what drive Earth's processes. 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.As a member, you'll also get unlimited access to over 70,000 lessons in math, English, science, history, and more.Plus, get practice tests, quizzes, and personalized coaching to help you succeed.
