Wegner assumed that about 225 million years ago all the continents broke apart. The super continents name was Pangea.Super Continent: Super ContinentAffective plates in the U.S.A: Affective plates in the U.S.A The major plates that effect the united states are the North American plate, Juan De Fuca plateAffective plates: Affective plates Pacific plate, and if you include Puerto Rico then it should include the Caribbean plate.Earthquakes: Earthquakes California is on the North American plate and the Pacific plate. Also known as the San Andreas fault. As the plates slip past each other it triggers earthquakes. Florida is in the middle of the North American plate so it is inactive.Home Hazard Zone: Home Hazard Zone Our home is in the St Andreas fault zone.Most Destructive Earthquake: Most Destructive Earthquake The most destructive earthquake in history was the Chile earthquake. It happened in 1960. It occurred on May 22 19:11:14.Destructive earthquake continued: Destructive earthquake continued It was in Valdivia, Chile and 1,655 people were killed. The magnitude was 9.5.The basic types of plate boundaries: The basic types of plate boundaries The three basic types of plate boundaries are divergent, convergent and transform boundaries. Divergent plate boundaries move away from each other .Boundaries continued: Boundaries continued Convergent plate boundaries collide with each other. Transform boundaries grind past each other.tsunamis: tsunamis Tsunamis are enormous ocean waves. They are generally caused by earthquakes.Tsunamis: Tsunamis They often exceed 100 miles per hour but can hit speeds up to 500 miles per hour.Energy waves: Energy waves The two types of energy waves are Primary waves and Secondary waves. A Primary wave is an earthquake wave in which rock particles vibrate parallel to the direction of wave travel.Energy waves continued: Energy waves continued A Secondary wave is an earthquake wave in which rock particles vibrate at right angles to the direction of wave travel.Difference in the Earthquake energy: Difference in the Earthquake energy A 7.2 Earthquake releases 32 times more energy than a 6.2 earthquake.Picture of 6.2 earthquake: Picture of 6.2 earthquakeSeismology: Seismology Reflection and refraction. It also helps with evacuation plans if an earthquake were to be located.Reflection and refraction: Reflection and refractionEarthquakes last week: Earthquakes last week Most earthquakes happened in Alaska last week.Can Scientists predict earthquakes?: Can Scientists predict earthquakes? Scientists cant predict earthquakes. Scientists know that their will be another earthquake but they don’t know when.How do scientists know when Earthquakes occurred?: How do scientists know when Earthquakes occurred? Scientists know when earthquakes occurred because they use data collected from as many Seismograph stations as possible. You do not have the permission to view this presentation.
