1.Show map of Earth’s fault lines/tectonic plates.NARRATOREarth’scontinents rest on massive slabs of rock called tectonic plates.Highlight plates.NARRATORTheseplates are constantly moving around, sliding past one another, going over andunder, and pulling apart.Move plates around the graphic slightly.

NARRATORThebreaks and cracks where these plates separate are called faults.Highlight fault lines.NARRATORWhentwo or more plates make contact while moving along their faults, it puts stresson rocks on both sides, which build up energy that is then released in the formof massive vibrations called tremors. We feel these tremors as the groundshaking beneath our feet – an earthquake!2.Brief, yet engaging footage of an earthquake.NARRATORScary,right? For cities that lie on or near fault lines, earthquakes are one of thetop concerns.

In order to guarantee the safety of their citizens, these citiesmake it a priority to know when and where an earthquake will strike, as well ashow strong it will be. But how can they detect that? 3.Scientists monitoring a seismograph/usingcartography equipment.NARRATORScientistscalled seismologists, who specialize in studying earthquakes and the movementsof tectonic plates, track earthquakes in order to establish where faults lie.To do this, they use a tool called a seismograph, a machine that picks upvibrations in the ground and draws them on a sheet of paper. Where thevibrations are stronger, the closer they are to the fault. With this data andthe assistance of cartographers, people who use special tools and equipment tomake maps, seismologists are able to make an accurate map of the Earth’splates, where they lie, and where their faults are located.4.

Back to the first mapNARRATORWiththese maps and the information they provide, seismologists can predict thelocation of the epicenter, the point directly over an earthquake, and issue awarning to the cities that sit at or near this location. This information isespecially important for cities that sit in an area called the Ring of Fire.Highlight the fault that makes the Ring of Fire.NARRATORTheRing of Fire is an area around the Pacific Ocean where a large number ofearthquakes and volcanic eruptions occur. The Ring of Fire is a geographicalevent caused by the shifting of seven different tectonic plates collidingtogether along their faults and causing ninety percent of the world’s earthquakesand eighty percent of the world’s largest earthquakes, affecting cities allaround the Pacific.

There are other areas of high earthquake activity, but noneas large or as active as the Ring of Fire.5.Blank space, questions appear as the narratorsays them.NARRATORLet’sreview. What are the spaces between tectonic plates called? What causesearthquakes? What kind of scientist studies earthquakes? What is the pointabove an earthquake called? What is the area called where most of the world’searthquakes and volcanic activity happen?
