Ozone
A molecule composed of three oxygen atoms, it blocks UV rays
Real World Example
Imagine you're at the beach, trying to enjoy the sun, but there's sand constantly blowing into your eyes, making it uncomfortable. Just like sunglasses protect your eyes from the irritant sand, the ozone layer acts as Earth's sunglasses, blocking harmful UV rays from reaching us. In this analogy, the sand is like UV rays that can cause damage, your eyes are like the Earth's surface, and the sunglasses are like the ozone layer, made up of three oxygen atoms, shielding us from potential harm.
