SciLink from 2-1 Notes

As part of the Section 2-1 notes, I was supposed to visit one of the sites that come up when I entered the code listed on page 47 of the notes on scilinks.com , and write about what I saw there and what I learned. I went to SciLinks, and chose this site. It's a pretty short description of how energy is released from stress in an earthquake. Apparently, when the two sides of a fault are pressed together, there is friction, which makes them resist the forces that try to move the sides of the fault apart. With that resistance, energy builds up, and deforms the fault until the fault breaks, and an earthquake is created. After the earthquakes, the return to thir previous state until enough energy builds up for a new earthquake.
