What Does the Atmosphere Do? Crash Course Geography #6

Much like a cell membrane, our atmosphere forms a protective boundary between outer space and the biosphere that allows for all life to exist on Earth’s surface. Today, we’re going to talk about its composition and layers (the troposphere, stratosphere, mesosphere, and thermosphere), follow the path of a sunbeam of light as it travels through space and (potentially) reaches Earth’s surface, and discuss how the greenhouse effect can be both a good and bad thing!

Dave Attenborough is an ABSOLUTE hero! and your impersonation was spot on! 😁

[GoyoPollo]

As someone with a degree in this stuff, I can say very well done! Wish some of my professors could have explained it like this!

We need more enthusiastic teachers like her!

Not sure if I'm right, but it seems that you started to speak more slowly and it contributes to the production value, keep up the great work!

[BrianHutzellMusic]

I'm celebrating Memorial Day 2023 by binge-watching CrashCourse. Thank you, Complexly, for making all of these great educational videos!

Disappointed that the pop tart kitty sunbeam didn't get torn to pieces as the energy diffused 😋

[GuiiBrazil]

Such a cool serie, I feel like I could go back in time and change every single decision of my professions lol
All this interesting info, without even mentioning the magnetic field. Life on earth seems more like luck than anything else.

on second thought this video was perfection
