I would imagine that the relative motion between the entry/exit portal would be more important than the absolute motion of the two portals.
Portal 2 ends with you (Chell) placing a entry portal on Earth vs an exit portal on the Moon.
That means the portals were ~2236 mph (aka Mach3) relative to each other.
Wouldn't that provoke all air in the Earth to get sucked to the Moon due to the difference in atmospheric pressure?
Yes, but the flow rate is only so much. It was only open for a short time before Glados closed it.
