    Hi subscribers, this is a reupload for a couple of reasons. Firstly, it was originally meant to be 4K but RUclips didn't render it at 4K quality, so I'm hoping with an increased bitrate it will work this time. Secondly, there were a couple of (minor) mistakes with the original which have now been rectified. I want this channel to be as high quality as possible so if there are some things I have done wrong I will always try to mend them and not to make similar mistakes in future! The original is still on the channel but is just unlisted for the time being. I will eventually take it down altogether. Thanks for the understanding!

      '...if there are some things I have done wrong I will always try to mend them and not to make similar mistakes in future!'
      That simple goal would save the world, but for now, it'll produce high-quality science entertainment. Thanks, Astrum!

    • @alexolas1246
      @alexolas1246 4 года назад +5

      the “ionosphere” seems to be another classification of altitudes, containing the thermosphere & parts of the meso- & exospheres. it’s defined as the bit where particles are ionized by solar radiation, whereas everything below it is called the “neutrosphere”.
      the “magnetosphere” arguably isn’t even part of the atmosphere at all, but part of earth’s magnetic field; it’s the zone where an astral body’s magnetic field affects charged particles. it extends to about 1/10 of the height of the exosphere, and apparently the ionosphere is just below it.

    • @GTIngold

    Very good video! I haven't seen that much detail about the atmosphere since I studied it in grad school. I like your pacing and presentation and the images you find to go with your narration are great. The only criticism I have is that the aurora are caused by charged particles from the sun spiraling down the earth's magnetic field lines rather than by radiation from the sun interacting with particles in the atmosphere. I look forward to more of your videos!

    • @eswing2153

    Where does the Earth’s spinning atmosphere stop, and the vacuum of space begin? At the Karman Line? Between the Exosphere and Thermosphere?
    Not all scientists agree that the exosphere is really a part of the atmosphere. Some scientists consider the thermosphere the uppermost part of Earth's atmosphere, and think that the exosphere is really just part of space. However, other scientists do consider the exosphere part of our planet's atmosphere.
    How is the atmosphere, which is a gas, and the Earth which is a solid, and the water, which is a liquid, all moving at the same speed as one body? And if the atmosphere is a gas, how is it different from other gases like wind from hurricanes or simple directional breezes? Inertia is the term that describes why we don’t sense the movement. But using the train or plane analogy, we must take into account the physical barrier, steel, aluminum, glass, etc...that prevents the resistance force to be felt. Roll down the window of your car and those forces will be felt. That leads to my question: at what point in the upper atmosphere does this invisible protective barrier exist? The exosphere or thermosphere or the Kármán line

    • @tims5268
      @tims5268 Год назад

      There is no resistance because Earth (and its atmosphere) are moving through a vacuum. There is no 'invisible protective barrier', gravity keeps our atmosphere stuck to earth (although we do lose some of it to space).
