Question: can the worlds atmospheric gravitation collapse and move the earths countrys?

Gravity is universal. I really like this explanation of how gravity works: http://science.howstuffworks.com/environmental/earth/geophysics/question232.htm

Basically, two bodies attract. Our planet is attracted to the sun and vice versa so it is basically falling around the sun. Imagine holding a ball on a string and swinging it around you in a circle. That’s sort of how gravity works. There are attractions with the other planets and the moon, too, which change the path a little. It’s not quite a perfect circle. We have an atmosphere because the Earth is big enough to hold on to the molecules that make up air: nitrogen, oxygen, carbon dioxide and some other good stuff. Gravity is why the air is “thicker” near the surface and “thinner” when you are at great heights. Planes fly faster at height because they have less air to move through. Have you ever been lightheaded or dizzy at altitude? Same reason, less air. The countries moving is a more complicated question. The earth is made up of plates that shift around. These are called tectonic plates and you can find more about them via google. There have been a couple of big earthquakes recently because of the plates shifting around. A big earthquake might come from just a little shift in the plates, just a couple of millimeters or a centimetre or so. If we had a big change in gravity, the plates would be affected but it would take a really big change to move those plates a large distance.
