High up in the sky — far above the clouds, the planes, even the tallest mountains — there is a special blanket of gas called the ozone layer.
You cannot see it or touch it, but it works like sunscreen for the whole Earth. It keeps every person, animal and plant safe from the Sun's harmful rays.
Let's go up and explore it together. Tap Next when you're ready! 🚀
Our air is built in layers, like a stack of pancakes. The ozone layer sits up high in a layer called the stratosphere.
Tap each layer to climb up and find out what's there:
The air you breathe is mostly oxygen. One oxygen piece is called an atom. Normal oxygen holds hands in pairs — 2 atoms.
Ozone is special: it is 3 oxygen atoms holding hands together! Scientists call it O₃
Build one ozone molecule — tap to drop 3 oxygen atoms into the empty spots:
The Sun sends out light we love — but it also sends invisible UV rays that can burn skin and hurt our eyes. The ozone layer soaks up most of those harmful rays before they reach us.
Long ago, people used special gases in old fridges and spray cans called CFCs. These gases floated up and started damaging the ozone layer, making a thin "hole" over the South Pole.
A thinner ozone layer means more harmful UV rays can sneak through. That worried scientists all around the world!
Was this good news or a problem? Tap your answer:
Here's the amazing part: countries around the world agreed to stop using CFCs. Slowly, the ozone layer is repairing itself! It shows that when people work together, we can heal the planet.
