Read, highlight and annotate (make sure you leave annotations like this one indicating why you chose to highlight that text) the article! Earthquakes You used models to find out what happens with the release of energy from an earthquake. Recall that an earthquake is a sudden motion or shaking of Earth as rocks break along an extensive surface within Earth. The rock masses on either side of the fault plane slip past one another. This slippage can be for distances as much as 10 m during the brief earthquake. The rocks break because of slowly built-up bending (how rocks break is based on how the energy moves) . The sudden release of energy as rock ruptures causes intense vibrations. These vibrations are called seismic waves or earthquake waves.
Student Handout_IS5T1A: Explain 2- Earthquakes Name Maximus Gannon Date 03-11-20 Period 5 Seismologists explain the occurrence of earthquakes in the following way. A fault is a surface between two large blocks or regions of rock, along which there has been rupture and movement in the past. Faults are very common in the rocks of Earth’s crust. Large-scale forces within Earth’s crust push the fault blocks in opposite directions. The movements of Earth’s plates cause most of these forces. You looked at a variety of different types of faults earlier in this chapter.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
