Week 4: Plate Tectonics Lab INTRODUCTION Since the plate tectonic revolution in the late 1960's, our view of how the world works has changed drastically. Plate tectonics successfully explains how earthquakes, volcanoes and mountain belts form and how the continents and oceans have evolved with time. One of the most useful pieces of information are magnetic anomalies recorded in the ocean floor that allow us to determine rates and direction of sea floor spreading through time and to reconstruct past plate configurations. In this lab you will do several exercises to gain a better understanding of plate motion and rates. Plate Reconstructions The evolution of the San Andreas fault system over the last 30 million years is shown below. The Pacific plate currently is moving past the North American plate at a rate of about 3.5 cm/year. 1. During what time (in millions of years) would you expect volcanoes near Los Angeles? It’s hard to predict an exact time of when volcanoes will be near Los Angeles. The part of the

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
