The explanation of the atmosphere moving the same speed as the solid body it's attached to is ridiculous. Speed would have to increase with altitude
consistently to make it work but there is nothing giving the higher, faster atmosphere energy to do so.
Your mistake here involves frames of reference. The top of the atmosphere is indeed moving "faster than" the atmosphere in which we go about our
everyday business. But relative to the ground, it is stationary.
The same thing would apply if you were to build the world's tallest flagpole from ground level to the outer limits of the atmosphere. The top and
bottom would move together, the pole would not stretch, bend, or break as a result of the altitude at the top, and you would not be able to discern
any speed difference between top and bottom because both ends of the flagpole would be motionless.
The same thing applies to a satellite in geostationary orbit. From outside the Earth's orbit, it would seem to be moving around with the planet at an
incredible rate. But if you (back at ground level) extended your enormous flagpole to touch the satellite overhead, you'd soon see it wasn't moving at
all. The flagpole would remain vertical, and the satellite would sit on top without moving. You'd look up and see nothing remarkable happening at
This isn't some linguistic trickery, it's just a 'thing' in physics that is difficult to wrap your head round. Put it this way, if you were travelling
in a train that was doing 100mph, and you held up a tennis-ball and let go of it, you wouldn't expect the tennis-ball to shoot off backwards at 100mph
in the other direction. On the other hand, everything you see through the windows of the carriage does
seem to be moving at 100mph in the
opposite direction to the train.
