This is the long and short amature of it:

It's somthing called PLATE TECTONICS. While the plates seprate from themselves, the other end will overlap making different forms of volcanos or/and earthquacks. As for the ocean ground, depending on the greatness of the tectonic plates, it will cause an earthquake and then a tsunami. Prime example, the tsunami in Japan back in 2011. As a result the earth size wll never change.
