The lithosphere of our planet made of large masses of rock called plates. These plates move. Features form at the edges of the plates from the activity that occurs at these plate boundaries.

On Chart One, you were to fill in the names of examples of features that form at each type of plate boundary. This exercise continues that assignment.

Below are some useful sources of information that supplement your textbook. Using these or other sources, write a brief description (with examples) and draw a diagram to illustrate how each feature at each type of boundary forms.
