Question

what type of plate tectonics would you expect to observe at the mid - ocean ridge?
a divergent plate boundary
a convergent plate boundary
a hot spot volcano
a subduction zone

Explanation:

At mid - ocean ridges, tectonic plates move apart. Divergent plate boundaries are where plates separate. Convergent boundaries are where plates come together, hot - spot volcanoes are not related to plate boundaries in the same way as mid - ocean ridges, and subduction zones occur at convergent boundaries.

Answer:

A. A divergent plate boundary
