Plate Movement Lab: Part II – Conclusion Questions
A. Divergent Plate Boundary  
1. Describe what the asthenosphere looked like after the oceanic plates were pushed apart.
It resembles a ridge or mountain chain.
2. What would happen to the molten material as it cools?
It would harden and create new land.
3. If this action continued on the ocean floor, what would be the effect on other tectonic plates on
Earth?
These plates would grow and push against other plates.
B. Convergent Plate Boundary – Oceanic Plate vs. Continental Plate 
1. Compare and contrast the continental plate and the oceanic plate.
The continental plates are much thicker and less dense than the oceanic plates.
2.
Which plate floated on top of the other? Why?
The continental plate floated above the oceanic plate because it is less dense.
3. What happened to the other plate?
The oceanic plate sank (was subducted) underneath the continental plate.

4.
If a plate is pushed into the asthenosphere, what will happen to it?
The plate would be melted back into the mantle.
C. Convergent Plate Boundary – Continental vs. Continental 
1. What happened when you pushed the two plates together?
The plates made a wrinkle and uplifted.
2. What land feature does that represent?
It resembles a mountain.
3. Did either plate sink into the asthenosphere? Why or why not?
Neither plate sank, because they have the same density.
D. Transform Plate Boundary
1. What happened to the plates as you rubbed them together?
They vibrated and broke apart into smaller pieces.
2. Did it feel smooth or rough as you rubbed the two plates together?
It felt rough and vibrated.
3. What would the vibration of rubbing the plates together represent in real life?
An earthquake
