Question

which type of plate boundary is most likely to occur at point a in the diagram?
convergent
divergent
transform

Explanation:

To determine the plate boundary at point A, we analyze the diagram:

• Divergent boundaries occur where tectonic plates move apart, allowing mantle material (magma) to rise (as shown by the upward arrow at A and the spreading motion of the lithosphere plates).
• Convergent boundaries involve plates moving toward each other (subduction or collision), which is not depicted here.
• Transform boundaries involve plates sliding past each other, with no upward magma movement or spreading, which also does not match the diagram.

The upward flow of mantle material and the spreading lithosphere plates at A indicate a divergent boundary.

Answer:

divergent
