Activity 3a. Knowing Plate Boundary

C F G

B
B B

Instructions:
• Color A with red and label “Middle • Color E with yellow and label “volcano”
Mantle/ Asthenosphere/ Magma” • Draw an arrow pointing left and color F
• Color B with orange and label “Upper with brown
Mantle” • Draw an arrow pointing right and color G
• Draw an arrow along the layer C that with brown
curves and points towards A. • Color H with green and label “mountain”
• Color C with gray and label “oceanic • Color I with black and label “rift
crust” valley/mid-ocean ridge”
• Color D with blue and label “ocean”
Questions:
1. How many plates are interacting in the illustration? How did you know?
2. Describe the interaction with C and F? What do you call this interaction? List down the three pieces
of evidence to support your answer.
3. Describe the interaction with F and G? What do you call this interaction? List down the three pieces
of evidence to support your answer.
4. Which plate is denser between Plate C and F? How did you know?
5. Is there shearing shown in the illustration? Why do you think so? (HINT: shearing plates are moving
sideways.)

B. The map below shows the relative motion of the plates. Using this map, complete the table.
