The inner core of the Earth is molten rock, called magma, it contains iron and is under pressure. The outer hard surface, or crust of the Earth is solid rock, but is not one solid mass. It is broken into segments called tectonic plates. These segments are continually moving and shifting. As they collide and rub together an earthquake is created allowing the magma to escape and create mountains and volcanoes. The tectonic plates also move apart and the different countries of today, separated by seawater, were once one large segment of the Earths crust, called Guandana. About 200 million years ago the tectonic plates separated and formed the countries as we see them on a map today, but, as the tectonic plates continuously move a few millimetres per year, maps and distances between countries will have to be changed in the distant future.
A related subject is the magma core of the Earth which creates magnetism, another natural phenomenon which affects the planet.
