Name the following plate margins based on the descriptions and diagrams, and perform a plate movement calculation.

here are the answers for Activity 2. I need the full text for Activity 3 to solve it.

Activity 2: Name the following plate margin.

1. The diagram shows two plates moving towards each other, with one plate being forced beneath the other (subduction). This is a destructive (convergent) plate margin.
2. The diagram shows two plates sliding horizontally past each other. This is a conservative (transform) plate margin.
3. The diagram shows two plates moving away from each other, with magma rising to create new crust. This is a constructive (divergent) plate margin.

Activity 3: Plate movement calculation

Question 1 is incomplete. Please send the full question for Activity 3.
