2 Synthesis of last classes Note all the things you can see. Start from land Shelf Slope Canyons Fans abyssal planes hot spot traces ridge transform faults 2 subduction zones 2 trenches even the remnant of a land/land collision Where would back-arc volcanoes be? Where is the oldest rock? Oldest sea-floor? You should be able to explain why all these exist! Why is the deepest part of the ocean just off the slope? http://oxbow.sr.unh.edu/class.html
