When a convergent boundary involves a continental landmass and an ocean basin, the result typically includes the following outcomes:
1. A chain of volcanic mountains will form on the edge of the continent or just offshore.
- Due to the subduction of the denser oceanic plate beneath the less dense continental plate, magma can rise to the surface, leading to the formation of volcanic mountains.
2. A deep ocean trench will form offshore.
- As the oceanic plate is forced downward into the mantle at the subduction zone, it can create a deep trench in the ocean floor.
These processes contribute to geological phenomena such as volcanic activity, mountain formation, and trench creation, which are common at convergent boundaries involving continental and oceanic plates.
