Description
How is new crust made, and why isn't the Earth constantly expanding like a party balloon? To answer these questions, we'll track the life, death, and rebirth of Earth's surface. Stops along the way include the Mid-Atlantic Ridge, a prize-fight between tectonic plates beneath New Zealand, and a stop for dessert on the Italian island of Vulcano.
Extra credit: Experiment with your carpets at home, pushing them together and testing which one sinks beneath the other.
