Shake, Rattle, and Roll
As we began to learn about Earth, we discovered that it is made up of many different layers, the crust, mantle, outer core, and inner core. The crust and the upper part of the mantle is often also referred to as the lithosphere. The lithosphere isn’t completely solid though. It’s actually broken up into many different pieces. We call these pieces tectonic plates. These plates fit together like puzzle pieces but rather than a puzzle that you may put together at home or school, these puzzle pieces are constantly moving, albeit very slowly. The location where these pieces meet is referred to as plate boundaries. Within these plate boundaries are faults, which is where earthquakes most commonly occur. The edges of these plates are rough so they sometimes get stuck against one another. Because the rest of the plate is moving while the edge is stuck, pressure builds up until they eventually break free causing the earth around it to shake, sending seismic waves to the surface and thus resulting in an earthquake.
Once we finished putting our information into a Google Spreadsheet, we then turned our attention to the Google Maps Engine. The Google Maps Engine worked much better than Google Maps for this particular project because we were able to import our spreadsheet straight into the program and it automatically plotted our points! You can take a look right below to see the map that was created that accompanied Luke and Izzy’s spreadsheet.
