Earthquakes PowerPoint Presentations - PPT
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. .
. 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..
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..
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. .
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 .

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.
Comparing and contrasting earthquakes. Have compared the impacts of earthquakes on a . MEDC. and a . LEDC. .. Have considered development as a key issue in . earthquake response. .. By the end of this section, you will: .
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:.
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..
Essential . Questions. What are earthquake magnitude and intensity and how are they measured?. Why are data from at least three seismic stations needed to locate an earthquake’s epicenter?. Where are Earth’s seismic belts?.
