PPT-Earthquakes release energy.

Page 51 BEFORE you learned Most earthquakes occur along tectonic plate boundaries Different directions of stress cause normal reverse and strikeslip faults NOW you will learn How energy from an earthquake travels through Earth . The Great California . ShakeOut. . NO. Caused by sudden release of energy. Tectonic earthquakes are focused on a fault. Induced seismicity. Volcanism. The Great California . ShakeOut. . Earthquakes caused by the movement of magma through the earth’s crust. Lesson objective: To be able to explain the characteristics and spatial distribution of earthquakes . Key terminology . Focus . Epicentre. Asthenosphere . Lithosphere . P and S waves . Surface waves . Macy and Caitlyn . Contents Page. 3 Earthquakes. 4 Volcanoes. 5 Hurricanes. Earthquakes. Put simply, an earthquake is a shaking movement of the ground. It can be a slight tremor or a violent juddering. Earthquakes are caused by sudden die. You can think of an Earthquake as a sudden release of energy Underground. The energy spreads out from the focus in waves called seismic waves. . The Great California . ShakeOut. . NO. Caused by sudden release of energy. Tectonic earthquakes are focused on a fault. Induced seismicity. Volcanism. The Great California . ShakeOut. . Earthquakes caused by the movement of magma through the earth’s crust. They Shape Our Landscape. As plates move, we may feel these movements as earthquakes. If there were no plate motions, our planet would not look like home. There would be no mountains, no valleys, no plateaus . . By : . Deavian. foster . Class : 5H. What is an earthquake?. A earthquake is a shaking of the earths crust and is a geological phenomenon . Earthquakes can cause intense vibration of the ground, soil liquefaction, and distortion of the ground. Earthquakes can happen almost anywhere but are most common along the boundaries of the tectonic plates. Earthquakes are primarily caused of movement of the tectonic plates. It lasts more than a few seconds.. Earth’s Dynamic Crust. Original Horizontality (law of superposition):. Assumption . that sedimentary/igneous rocks form in horizontal layers . Deformity. Folded: Layers are bent/curved. Deformity. Part 3: Earthquakes.   . outline differences in P, S and L energy waves produced by an earthquake .   . identify energy transfers and transformations involved in L waves as they travel along the earth’s crust . : December 1811, January 1812, February 1812 . Eastern U.S. earthquakes less frequent, but more widely felt. Crust is older and transmits stress. Intraplate Earthquakes. Earthquake Size and Characteristics. Why you need to prepare for the next earthquake . Alaska has more earthquakes than any other region of the U.S. . And in fact is one of the most seismically active area of the world..
