Hey Jamie! Are you ready for the Geography test? We can test each other if you want!
Hello? Earth to Jamie...
I should have studied last night...
Oh, Jasmine. Well uh, you see... I don't know anything about what's on the test!
You what?! You don't know anything about the "Spheres" of the Earth?!
The wait? Aw man, I have no idea what you are talking about!
Ugh, okay. Let me explain to you what the "Spheres" are, then
To start off, the Earth is divided into 4 subsystems, or spheres. The 4 spheres are the Atmosphere, the Hydrosphere, the Lithosphere, and the Biosphere. All of these subsystems are connected, and interact with one another. Did you get all that?

Sure! I'll run through all of them briefly. Let me start with the Atmosphere.
Most of it. Do you mind telling me the features of the 4 spheres?
Atmosphere is a fancy name for air, which is everything around us. Its name comes from the Greek word "Atmos."
