Earth has been restless ever since it solidified from
a giant ball of gas more than 4.6 billion years ago. Since then,

But what exactly are these awe-inspiring and
devastating natural phenomena? Why do they occur, and why are they

By studying earthquakes
and volcanoes, you can begin to understand the inner workings and
layered composition of Earth. Discover plate tectonics, and see how
volcanoes and earthquakes are just the consequences of the constant
movement of the planet’s parts. Erupt two types of volcanoes to
imitate how lava hardens into rock and volcanic mountains grow.
Build a working seismograph to see for yourself how scientists
measure earthquake forces. Learn about the most famous volcanoes,
earthquakes, and tsunamis in history.
