Go to the first page and click on Plate Tectonics Activity.
Position your cursor over each of the floor plates. Use your mouse to drag the plate in the direction of the
arrow. Label the type of boundary shown and briefly describe what you see happening. In addition, looking
at the world map, you will see locations worldwide that exemplify this type of boundary. List two examples
of locations in which we would find each type (highlighted in white). You may need to do a little more
research to identify exact locations.
