1. In the following boxes, draw arrows to represent the type of boundary listed above it.
Under the arrows, show the direction of the convection currents in the mantle. Then write
in the box the most common formation or event that would occur at that boundary.
Convergent
Continental Plates
Convergent Cont/
Oceanic Plates
Divergent Plates
Transform Plates
2. Name 5 of Earth’s plates and then draw a circle around the oceanic plate/s that you
name: ________________________________, _______________________________,
_______________________, ______________________, _______________________
3. We must often use models to represent real objects. An apple could be used to represent
the layers of the Earth. Name 2 advantages and 4 limitations of using an apple as a model
for Earth’s layers.
Advantages – 1.___________________________________________________________

4. What layer inside the mantle causes the plates to move?
5. Plates are just “pieces” of the ____________________________ (one of Earth’s layers).
6. Why does it occur in this layer and not the inner core?
7. Which of the Earth’s layers am I referring to when I say plates?
8. When continental plates collide, mountains can form. When continental and oceanic
plates collide, volcanoes can form. What makes oceanic crust different for this event to
occur?
9. Fill in another word or two words that mean the same as –
Convergent - ______________
Divergent - ______________ Transform - ___________
10. Name each layer of the Earth above and then describe its state of matter and relative
density.
11.
11. Look at the balance on the left.
The small rock has a mass of 6 grams.
What is the mass of the large rock?
12. If these rocks were formed due to
heat and pressure, what type of rock
would they be?
13. What is the name of the large plate at the center of the Ring of Fire?
14. What occurs in this area?
15. Why is it called the Ring of Fire?
16. Chad measured the mass of a gray rock and found it to be 3 grams. The volume of the
rock was 5 mL. He used these data to calculate the ____________ of the rock, which is
_________.
17. You know that the density of water is 1.0 g / mL. Can you infer what type of rock the
above rock is you calculate its density?____ What is it? ______________________
