This is an extremely stupid question but how hard is the iron of the inner core, is it like a rougher-looking armor plating and as hard as the iron we use for such things?
Again sorry if it is an ignorant question. -
Wher did all of the matter that makes up the earth come from? Did all of this matter always exist? Are planets still being formed?
-
you talk like a pre school teacher but I'm still enthralled and I'm 32.
-
great work guys.
-
Lol 3:00:
Phil:" It's made up of many different plates"
Me:"Lol It's made up of many different PLAITs!!"
DADUM CHHHHH -
Saying "twelve hundred" instead of "one thousand two hundred" irritates me. The numbers are hard to grasp this way, I have to pause the video and think every time. Because I really want to understand and put this information into my own context.
Since it seems that you have put A LOT of thought into every detail of this series in order to make it relatable to as wide of an international audience as possible, this might be something you want to change in the future.
Other than that, your astronomy lessons are one of the best. That's a profound statement, one that's actually obvious :) -
4.5 billion years ago huh?
-
I disagree with the last bit. We should not keep it so that the Earth is the only inhabitable planet, we should make it the first of the inhabitable planets.
-
I wonder what the song to the intro is? Anyways, if their is another planet which is habitable wont it be in another universe? Because I think that the planet position will be the same in all universe. Please tell me if I am wrong. Thanks.

Notice how this guy uses mostly cartoons to convince you. The earth is flat. Its funny because the only time you see curvature is on tv.
-
Planet Earth is blue and there's nothing I can do
-
Bruh
-
There needs to be one more lower note in the intro's ending.
-
Wait, if the Earths core is iron and nickel, couldn't that accumulate in the core just like a pre-supernova star and eventually create a mini-supernova?
-
I just gotta say these thumbnails and also the thumbnails in the Anatomy course are the best i have ever seen just beatiful
-
That's cool
-
Wow
-
I wish they would have explained how Magnetism works before this video and the last. They did it with Gravity and it helped me so much.
I don't get how/why the poles are more magnetic and yet have less magnetic field...? -
i like the way the earth rotates, really makes my day.
-
Thank you very much for making this video, Phil Plait and the rest of Crash Course Astronomy! It was really interesting to learn about our amazing home planet, I just hope my future children and grandchildren will see the planets beauty before we humans destroy it all.
Although I am very content with your videos, I was a little bit disappointed that you did not mention the Latin and Greek names of the planet: Tellus and Γαῖα.
