Beakman uses a chocolate-covered cherry as a demo of what the layers of the earth look like. He then demonstrates the earth plates by showing a ball with plastic plates glued on it to explain plate techtonics. He creates a simulation of two tectonic plates sliding past each other. He uses two planks side by side connected with sticky paper on top and has bobble heads on each to capture the movement (like a seismograph). They push the plates in opposite directions to demonstrate how an earthquake occurs.
Tsunamis are giant, powerful waves most often caused by earthquakes beneath the ocean floor. Their incredible power can destroy entire communities, then drag the debris out to sea. This video shows what causes tsunamis and the importance of evacuating any area under a tsunami alert.
