Final answer:
If two oceanic plates are explored at a convergent boundary, one can observe volcanic activity, earthquakes, and mountain formation.
Step-by-step explanation:
If two oceanic plates are explored at a convergent boundary, volcanic activity, earthquakes, and mountain formation can all be observed. Convergent boundaries occur when two plates collide, and one plate is forced beneath the other, a process called subduction. As the subducting plate descends into the mantle, it can cause volcanic activity and earthquakes. Additionally, the collision of the two plates can lead to the formation of linear and curved mountain belts.
