12), Seek, evaluate, and use a variety of specialized resources available from libraries, the Internet, and the community to find scientific information on Earth's history
So the difference in the P- and S-wave arrival times determines the distance between the epicenter and a seismometer. The Richter scale was created in the 1930s to assign a single number to quantify the energy released during earthquakes. Construct an oral and written argument supported by empirical evidence and scientific reasoning to support or refute an explanation or a model for a phenomenon or a solution to a problem.
