Question

task: tectonic plates
instructions
use the diagram provided to complete the activities.
activity 1 of 2
what plate motion is happening at point a?
a. a convergent boundary where two plates collide.
b. a divergent boundary where two plates pull apart.
c. a transform boundary where two plates slide past each other.
d. not enough information is given to be able to identify the plate motion.

Explanation:

A convergent boundary occurs when two tectonic plates collide. In the diagram, at Point A, one plate (oceanic) is being forced under another (continental), which is characteristic of a convergent boundary. A divergent boundary (Option B) involves plates pulling apart (like at mid - ocean ridges, which is Point B in the diagram). A transform boundary (Option C) has plates sliding past each other. Since the diagram shows subduction (oceanic plate going under continental plate) at Point A, it is a convergent boundary.

Answer:

A. A convergent boundary where two plates collide.
