Plate Boundary - Cross-Section Challenge
Using a map of the world’s plate boundaries, draw a cross-section as if you were to travel from the coast of
New Zealand (Tonga Trench) all the way across the Pacific Ocean to the Chile Trench. What plate
boundaries would you cross? What is the plate movement at each? Draw arrows and include labels for all
of the features. (trenches, ridges, boundaries…)
Using a map of the world’s plate boundaries, draw a cross-section as if you were to travel from the coast of
South America to the coast of Africa. What plate boundary would you cross? Label the oldest rocks and
the youngest rocks on your diagram and include all features found along the way.

Using the diagram above, write a well-organized paragraph to explain how plate tectonics
relates to the existence of volcanoes and the occurrence of earthquakes.
