Lab: Patterns of Seismic Activity
In this activity, you will be plotting the locations of active volcanoes, growing mountains, and earthquakes. Plot the mountains with a green triangle (▲) and be sure to label them by name. Plot the volcanoes with a red triangle (▲) and be sure to label them by name. Plot the locations of the earthquakes with a blue dot (●). You do not need to label the earthquakes.

Step #4
Let's figure out why the spectra of these galaxies look different. An object’s motion affects the energy emitted by that object. If it is moving away, the wavelength of the light it is emitting is stretched. If it is moving towards you, the wavelength of the light it is emitting is compressed. See the image to the left. Please watch this video on the doppler shift before proceeding. When you are done, use this information to answer the conclusion questions on the back of your lab sheet.
