Draw a diagram of an oceanic-oceanic divergent boundary. Be sure to: indicate the relative plate motions, label the crustal types and underlying features (such as the lithosphere, asthenosphere, and where the magma forms), and indicate the distinctive features that form at this type of plate boundary. Please upload a picture or scan of your drawing. You must draw the sketch yourself. Images from outside sources will not be accepted and will score zero points. If you are unable to upload a picture for this question, you may e-mail me your sketch. Please note that the sketch will need to be sent within 10 minutes of completing the exam. We can discuss alternatives if you are unable to submit the sketch on time, but you will need to meet with me.
