ELI5: Explain Like I'm 5

Atmospheric layers

Atmospheric layers are like layers in a cake, but instead of cake, it's our air that surrounds us. Just like how we have different types of cake layers such as chocolate and vanilla, there are different atmospheric layers divided by their unique characteristics.

The first layer that we have is called the troposphere, and it's where we live! This is where we breathe, fly our airplanes, and where our weather happens. The troposphere is like a blanket that wraps around the Earth and keeps us warm at night.

The next layer is called the stratosphere. This layer has lots of gases which help protect us from the harmful rays of the sun. This is why we see lots of airplanes flying in this layer – it's much safer and helps fuel efficiency.

Next, we have the mesosphere, where meteors burn up when they fall to Earth. It's very cold here and not many things can survive.

Lastly, we have the thermosphere. This is where the northern lights happen! It's super hot here because it's close to the sun, but there aren't many particles up here as well.

In conclusion, imagine the Earth as a cake and our atmosphere as different layers within that cake. Underneath that cake is the Earth's crust and the other layers that make up our planet, but that's a story for another day.
