                                            Earth

                      Today you are a geologist on a journey around the globe
                        in search of different types of plate boundaries. As
                          you have learned in class, the earth is broken up into
                          plates. These plates are in constant motion, and
have led to the theory of plate tectonics. This theory states that pieces of
earth’s lithosphere are in constant motion, driven by convection currents in
the earth’s mantle. The places where they meet are defined as plate
boundaries. The types of plate boundaries that you will be looking at today
on Google Earth are transform, divergent, and convergent boundaries. You
will find several different places around the earth where you will label and
discuss that type of boundary. Below you will find instructions as well as
links to get you started on your journey.

This link will open up Google Earth, but it is a .kml file that will allow you to
see the different plates and where they meet.

First, we will need to create a folder in My Places (left side of the screen).
To do this, right click under Places and select Add --> Folder. Title the
folder your First and Last Name. Here, we will store all the places we visit.
You will print all of them out when you are done.




The first plate boundary we will find is the San Andreas Fault.
   In the search bar, type San Andreas Fault, California. It will ‘fly’
      to the spot. Make sure you spell it correctly! If you don’t, you
      will not be at the right spot.
   Here you will use the place mark to pinpoint its location.
   You will need to name it and make sure you are placing it in your
      folder under My Places (located on the left side of your screen).
   In the window under description, you will need to answer the following:
          1. Any major geographic landforms?
         2.   Type of plate boundary?
         3.   Explain what occurs at this plate boundary and why?
         4.   What plates are involved at this plate boundary?
         5.   What types of crusts are involved? (i.e. continental colliding
              with oceanic, etc.)

Now let’s ‘fly to’ the Atlantic Ocean to find the Mid-Atlantic Ridge. You will
see the ridge running through the middle of the ocean. Again…
     Here you will use the place mark to pinpoint its location.
     You will need to name it and make sure you are placing it in your
       folder under My Places (located on the left side of your screen).
     In the window under description, you will need to answer the
       following:
          1. Any major geographic landforms?
          2. Type of plate boundary?
          3. Explain what occurs at this plate boundary and why?
          4. What plates are involved at this plate boundary?
          5. What types of crusts are involved? (i.e. continental colliding
              with oceanic, etc.)

Lastly, let’s go to the Himalayas. Type in Mount Everest in the search I-
beam, and let it fly!
     Here you will use the place mark to pinpoint its location.
     You will need to name it and make sure you are placing it in your
        folder under My Places (located on the left side of your screen).
     In the window under description, you will need to answer the
        following:
           1. Any major geographic landforms?
           2. Type of plate boundary?
           3. Explain what occurs at this plate boundary and why?
           4. What plates are involved at this plate boundary?
           5. What types of crusts are involved? (i.e. continental colliding
               with oceanic, etc.)

To print:
    Make sure you have your folder selected under My
      Places
    Make sure that your place marks are in your folder.
      Go to File, Print
      Select Selected Folder in My Places and click print

If you have time to spare, then go and find:
    The Andes Mountains, Peru
    Mount Vesuvius
    Sumatra, Indonesia (This is where the 2004 Tsunami occurred due to
      an earthquake off the coast of Indonesia. See if you can figure out
      why it happened.)
