A) The Earth spins at the same speed. What you are talking about is the tangential speed.
B) The tangential speed is not much faster at the equator than 100km South or North of it.
C) The speed difference would not explain why they don’t cross the equator. It may explain (partially) why there are no hurricanes further away from the equator.
I’m guessing it’s because they rotate in different direction in the northern and Southern hemisphere.
So crossing would imply switching direction, which would require to put that energy “somewhere” and it’s physically not possible.
No. It’s because the earth spins faster there. Them turning a certain direction is a result, not a cause.
