Volcanic and Seismic Events as Proof of Plate Tectonic Theory

Volcanic and Seismic events are major pieces of evidence towards proving that plate tectonics theory is valid. A seismic event is the transient motion and release of kinetic energy caused by sudden failure of the earth’s crust, usually felt as shaking or tremors in the rock mass. Seismic events range in size from barely perceptible tremors to major earthquakes. Volcanic events occur when there is a release of magma, gas and ash from the Earth’s crust. The entire outer surface of the planet is divided into these plate formations with approximately 30 in total. These different plates vary in size from over 100,000,000 square miles, for example The Pacific Plate, to the Galapagos micro plate at 12,000 square miles. Fault…
