Rating: 4.0; Vote: 1
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!

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?

If you got rid of all the people tomorrow, there would be no systems. But if you got rid of all the systems tomorrow people will build new ones. Systems are ephemeral and temporary, useful mediums for human activity. But they are not more worthwhile than any people or persons who use them to advance. Systems. They are the shared frameworks of our minds.

In entire life, when the word -sunbeam- was spoken, the image of a cat wearing a strawberry Poptart never came to my mind. Not once. And I have a really good imagination. I don't suppose the animator lives in a state that has legalized pot? lol

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.

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.

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!

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!
