Tropopause

The tropopause is a special layer in the sky. It is the place where the lowest part of our atmosphere, called the troposphere, meets the layer above it, called the stratosphere. This is where the air stops getting colder as you go higher and starts to get warmer.

The tropopause is not the same height all around the world. Near warm places around the equatorial regions, it is about 17 kilometers (11 miles) up. But near cold places, like the polar regions, it is lower, around 9 kilometers (5.6 miles) above the ground.

This layer helps control how air moves. It can change the weather we feel closer to the ground. Scientists study the tropopause to learn more about Earth’s climate and how our planet works.
