The Physics Of An Earthquake

The Physics Of An Earthquake Earthquakes are vibrations produced in the earths outer layer, or crust, when forces pushing on a mass of list inhibit the friction holding the rock in place and blocks of rock slip against each other. The vibrations can range from barely evident to verry destructive. There are six types of shock waves. Two are classified as body waves which means they travel through and through the earths interior and the other four are surface waves. The waves are changed by the rock types or formations they hit.

Primary or compressional waves (P waves) address particles moveing back and forth in the same direction as the waves are traveling, secondary or transverse shear waves (S waves) tear vibrations perpendicular to their direction of travel. P waves always travel at higher velocities than S waves. Three general classes of earthquakes are instantly recognized as tectonic, volcanic, and artificially produced. The tectonic variety is by far the most destructive. The most commen ca...If you want to get a full essay, order it on our website: Ordercustompaper.com
