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!

Yea! Nyanwave
I have watched this since I was a kid, I say it’s just as good as it used to be.
Thanks…we "Love" these for Home School learning!
Loved your Sir David Attenborough impression!
Thanks!!Is there anyone preparing TOEFL tests by listening to crashcourse?
6min10 nice stereo effect dude
thank you for making this topic so accessible. all throughout school i dreaded my dry and boring science classes & i just couldnt engage with it. this series is so wonderful!
Wow. I had forgotten about the nyan cat
So important to inform about natural science. Good made videos. We opened a explorer channel for young and older explorers "Forsche mit uns" and want to motivate to explore nature together with children.
Always here for an Attenborough reference
Shouldn't this be about 'Metereology?' It's also covered there. Geography is defined by its etymology. Study of land formations/topography and distances; broadly defined.
This is slowly becoming my favorite Crash Course series!
1:25 Air is a mixture of gases that are odorless, tasteless, dissolve instantly in liquid, and among the more deadly poisons known to man
Great video, and I love your Attenborough impression 😎
Another good place to go for more videos about the atmosphere is Dr Simon Clark: https://www.youtube.com/watch?v=aiZ-ui0lK-U and many more.
Great Video as always Crash Course
Thank you very much for a very interesting course. I understand how the earth is heated from the sun. My question is how much heat is generated from the core of the earth to heat our atmosphere. My second question is the core of the earth getting cooler? The heat that is in lava is this just from the cooling of our earth from when it was formed 4+ billion years ago or is something else keeping the inside of the earth hot?
As a former atmospheric science and meteorology major in college, looking forward to the next few episodes!
Amazing episode!
She’s staring into my soul
on second thought this video was perfection
Loving this series!
