What happens in the bowels of the earth?

The process of internal transformation of the Earth has not stopped. They will go on for long: thousands, perhaps millions of years. The earth is continuously rotating around its axis. This rotation creates a gravitational force that pulls everything that is on Earth's surface to its center. These same forces cause less robes cinders put pressure on the heated to millions of degrees the Earth's core. At the core of our planet, as in a huge sealed pot, boil all that what is in the mantle and crust. Raging in the heart of the world's "fiery dragon" constantly breaks through the viscous layer of the mantle to the Earth's surface. When he manages to reach the Earth's crust - the disaster may occur, namely: an earthquake or volcanic eruption.
