This topic will shake you up Stress Stress a force energy that acts on rock to change its shape or volume Types of Stress Tension pulls or stretches rock so that it becomes thinner in the middle This happens at divergent plate boundaries.

Revitalisation. John McDonagh, Jacky Bowring, Lincoln University, . Harvey Perkins, University of Auckland, New Zealand. . Background. Christchurch CBD retail struggling since 1970’s. 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 . . 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. 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 . 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. . William Mackaness, Carol Blackwood, Charlotte Graves. Institute of Geography.
