Welcome, everyone! Today, we’re focusing on the stratosphere, the second layer of the atmosphere. Can anyone tell me how high it goes?

Exactly! This layer plays a crucial role in filtering ultraviolet radiation through the ozone layer. Why do you think that’s important?

Right! Let's remember that with the acronym "OZONE": O - Ozone, Z - Zaps UV rays, O - Ongoing protection, N - Necessary for life, E - Essential layer. Now, how does temperature behave in the stratosphere?

Yes! This contrasts with the troposphere below, where temperature decreases. Let’s recap: stratosphere is high, protects us, and has increasing temperature!

Now, let’s dive deeper into the ozone layer. What does the ozone layer specifically do?

Correct! Ozone is crucial for filtering out harmful UV rays. Can anyone describe what happens if the ozone layer is depleted?

Exactly! Let’s remember: Ozone = Protection from UV. Alright, how do human activities affect this layer?

Yes! CFCs break down ozone. To summarize: the ozone layer protects us from UV, but we must be careful of human impacts.

Let’s compare the stratosphere to the layers above and below it. What’s the layer just beneath it?

Good! In which layer do we experience weather?

Right! Weather occurs in the troposphere, while the stratosphere is stable and lacks weather changes. Now, what’s the layer above?

Correct! Comparing temperature behaviors: the troposphere cools, the stratosphere warms, and then the mesosphere cools again. Let's remember: 'T-S-M' for Troposphere <-> Stratosphere <-> Mesosphere.
