Earthquakes

IntroductionThe major contributor that is involved in most of the geologic formations on Earth is the plate margins. The plates have an approximate thickness of 100 kilometers. This is not very thick when compared to the radius of Earth, which is a radius of 6000 kilometers. The major plates are made up of Continental and oceanic crust. When these plates move they produce temblors. quake Movement about of the time we regain upon about earthquakes everyday in the news. Exactly what makes an earthquake? An earthquake is produced when in that respect is a sudden release of ability, which causes a ruddy shaking in the crust of the Earth. This release of energy is ca employ when there is a build up of song of two lithospheric plates. When these to lithospheric plates luxate over against one another, clank will cause the plates not to move. Because these plates do not move, the stress that is exerted on them causes a change in shape of the plates. everyplace a period of tim e, the stress that is being exerted on the plates increases to a point that causes the plates to move suddenly, producing the earthquake. The stress that was create up is released finished the earthquake, only to build up again in time. Most of the time earthquakes are produced along gaolbreak lines.

A imperfection line exist where there is a crack in the crust of the Earth where there has been a movement of the plates (MSN Encarta, 2008). Earthquake MeasurementThe energy that is produced by an earthquake is hereditary through unstable waves. A seismograph is a machine that is used by scientist to prevent and record the seismic wave s. The seismograph is able to detect both p! lain motions and vertical motions of the movements of the ground. The seismograph records these movements as a...
