The cycles within which earth's matter moves are closed systems. This means nothing is gained or lost from the system; it only changes from one form to the other. The total amount of matter on earth remains the same. Using tectonic plates as an example, divergent boundaries occur where new oceanic crust is being created. New crust is being created and simultaneously the same amount of crust is being destroyed at convergent margins.
Physically, we would feel very less gravity, so we can travel, by our own body force, we would feel very less weight on our body.
Emotionally, it would be my best moment.... i'll just forget about countries on the Earth & think like a citizen (Human) on Earth
Hope this helps!
