The key information covered on this PPT includes: Normal, Reverse, Strike-Slip Faults, Divergent, Convergent, Transform Boundarie It plots these vibrations on a seismograph. 7th grade Science; 2 Earthquakes. An earthquake is the result of a release of stored energy in the Earth's crust that creates seismic waves. Learn vocabulary, terms, and more with flashcards, games, and other study tools. An M6 earthquake releases 7.8 x 10 13 joules, and an M7 radiates 2.1 x 10 15 joules. Seismographs are machines that detect and measure seismic waves caused by earthquakes. Mention statewide and local awareness programs (such as the ShakeOut) that help communities prepare and practice for such events. Scientists identify four types of faults, characterized by the position of the fault plane, the break in the rock and the movement of the two rock blocks. Since the edges of the plates are rough, they get stuck while the rest of the plate keeps moving. This movement may occur rapidly, in the form of an earthquake - or may occur slowly, in the form of creep. Let's start this scientific quiz! • The focus is the point on the fault surface where motion begins. Q.
