Move it, move it !!. What are they?. Fault: a break or fracture in the crust of Earth.. Earthquakes: shaking or trembling of the earth caused by movement along a fault.. Uplift: upward movement of Earth’s crust.. By. : 10 grade. What is an earthquake ?. Simply, earthquakes are the rumblings, shaking or rolling of the earth's surface. It is usually what happens when two blocks of the earth suddenly slip past one another, or break apart from each other as a result of tension caused by prolonged energy build up. . The Earths crust . The earths crust is in constant motion.. Volcanoes and earthquakes arise as sections of crust push . toghether. or pulled apart. Volcanoes and earthquakes are more common in certain parts of the world. By monitoring ground vibrations scientists can sometimes. . Compare and contrast two of the . United . States’ . greatest . earthquakes. . . Earthquake. . An . earthquake.  is what happens when two blocks of the earth suddenly slip past one . another.. Earthquake. – shaking and trebling that results from the movement of rock beneath Earth’s surface.. Plate movement causes earthquakes from stress and faults in Earth’s crust. When the rock breaks earthquakes happen. Chapter 2 Section 3. Objectives. F.2.3.1. Explain how a seismograph works.. F.2.3.2. Describe how Geologists monitor faults.. F.2.3.3. . Explain how . seismograph data is used.. The Seismograph. Seismic waves cause the seismographs drum to vibrate but the suspended weight with the pen attached moves very little. Therefore the pen remains still and records the vibrations on the drum.. 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 . Earthquakes result from sudden motions along breaks in Earth’s crust and can affect landforms and societies.. An entire branch of Earth science, called . seismology. , is devoted to studying earthquakes.. 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.. Great earthquakes (Earthquakes larger than magnitude 8) rock the state on average every 13 years since the 1900. . An . earthquake. is a shaking of the ground caused by the sudden movement of large blocks of rock along a fault. Earthquakes occur along faults.. A . fault. is a fracture, or break, in Earth’s lithosphere, along which blocks of rock move past each other.. What are Destructive Forces?. A destructive force is a process that lowers or tears down the surface features of the Earth. . Examples of Destructive Forces:. Destructive forces can occur in many ways. The following are common examples of destructive forces:. . What Is an Earthquake?. An . earthquake. is the vibration of Earth produced by the rapid release of energy. Energy released radiates in all directions from its source, the . focus. . Energy is in the form of waves. By: Dan Arrington. EAS 4480. Spring 2012.
