Sky's Tall Cake
What are the layers of Earth's atmosphere?
Look straight up. Past the clouds, past the airplanes, past the place where blue fades to black, there's a stack of invisible floors above your head. The air isn't just one big blob — it's layered, like a cake nobody can eat. Five floors, each with its own weather, temperature, and surprises. Let's climb.
Ground floor: the troposphere. This is home. Every cloud you've watched, every storm, every breath you've taken, every bird and kite and weather forecast — all of it lives here, in the bottom few miles. It's the thinnest layer, but it holds almost all the air, packed tight near the ground because gravity hugs it close.
