From what I understand, air gets thinner the further up you go. This I assume is because Earth’s gravity pulls all the heaviest particles down to its centre. I’m wondering about gravity itself though, is there a gradual shift in the strength of gravity as there is in the consistency of the air, or does gravity apply to the whole field surrounding the Earth up to the very perimeter and then quickly fall off?

The strength of gravity falls off with distance squared. This is the distance to the center of mass of the object though. So there’s about 6.3k km to center of the earth. If we were to double that distance by going 6000 km up, you would only feel 1/4 of the gravity, so about 2m/s^2 acceleration
