Tectonics

 Aside from being interesting in and of their own right, meteorites can give us information about the composition of our own planet.

The Big Bang started it all, bringing the universe into being.

Earth in its early stages was a hot planet, not capable of supporting life until it could cool down.

Plate tectonics- the moving of continental crust over the interior mantle- explains much of how the world works today, and how it gradually changes. 

A central video display looks at plate tectonics and its most visible  feature- volcanoes.

Earthquakes tend to happen along the edges of plates, though not exclusively. At their worst, they are the most violent force of nature.
