Earth has been restless ever since it solidified from a giant ball of gas
more than 4.6 billion years ago. Since then, earthquakes have shaken the
continents and oceans, and volcanoes have spewed out the molten insides of
our planet. But what exactly are these awe-inspiring and devastating natural
phenomena? Why do they occur, and why are they often in the same regions? How
have they affected human civilization?
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 the force of
an earthquake. Learn about the most famous volcanoes, earthquakes, and
tsunamis throughout history. A 32-page book guides your experiments and
discoveries.
