Deformation. The process of when a rock changes because of stress. Compression. -rocks push together (squeezing). Tension. -rocks pull away from each other (stretching). Rock layers bend when stress is placed on them. But when the stress is placed on rocks, they can reach their elastic limit and break. 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. 8.53. Write a narrative with supporting text describing the effects of the New Madrid Earthquakes of 1811-12 on the land and people of Tennessee. (G, H, . TN). Bell Ringer. : What might this map represent? Why do you think so? . 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. 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.. 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.. Earthquakes. What if you knew the epicenter was . 572 . km from Vancouver?. Earthquakes. What if you ALSO know that it is . 884 . km from Prince Rupert?. Earthquakes. Finally, you also know that the epicenter is . 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:. 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: Dan Arrington. EAS 4480. Spring 2012. Image obtained from: http://www.survival-goods.com/What_is_an_Earthquake_s/269.htm. Background Information. Richter Scale. Measures magnitude. Energy released. Content Purpose:. Explore the scientific theory of plate tectonics by describing how the movement of Earth's crustal plates causes both slow and rapid changes in Earth's surface, including volcanic eruptions, earthquakes, and mountain building. .
