Question 2 - worth 10 marks
The following diagram (Figure 4.1) shows four crustal plates (two continental and two oceanic plates), the boundaries between the plates (numbered 1 through 3) and the location of a volcanic arc. Based on the diagram, answer the following questions:
- Boundary 1 is a convergent boundary. In what directions are Plate A and B moving from? (Use cardinal directions in your answer) (1 mark)
- A volcanic arc is located on Plate D therefore Boundary 3 must be what type of plate boundary? (1 mark) Explain what is happening along that boundary to produce the volcanic arc. (3 marks)
- Boundary 2 must be what type of plate boundary? (1 mark) Describe the direction of movement for Plates B and C, and the features that must be located at that boundary. (4 marks)
