1 Name: -------------------------------------- Date: -------------- Lab 3 Plate Tectonics Required materials Pencil Colored pencils Computer with Google Earth software loaded In-class lab exercises Part 1 Plate processes The diagram below is a simplified representation of an ocean-ocean divergent margin. 1. Label the oceanic lithosphere, the asthenosphere and the zone of melting, and the mid-ocean ridge. 2. Draw arrows on the plates to indicate the directions in which they are moving. 3. Draw a second set of arrows to show the direction of flow in the asthenosphere. 4. What feature would you find at the center of the mid-ocean ridge?

2 The diagram below is a simplified representation of an ocean-continent convergent margin. 1. Label the oceanic lithosphere, the asthenosphere and the zone of melting. Indicate the regions where earthquakes may occur. 2. Draw arrows on the plates to indicate the directions in which they are moving. 3. Draw a second set of arrows to show the direction of flow in the asthenosphere. 4. Draw and label the locations of the trench and the accretionary wedge.

3 The diagram below is a simplified representation of a hot spot. 1. Draw arrows on the plate to indicate the direction of movement. 2. Label which island is the oldest and which is the youngest. 3. What information do hotspots like this give us about past plate movements?
