Answer: 1. Island Arc, 4. Mountains, 5. Trench
Step-by-step explanation:
A thick less dense continental plate and a thin, dense oceanic plates are two tectonic plates that comes together to create an oceanic-continental plate boundary. The process is called subduction.
The convergent boundary forms strong earthquakes, volcanic mountains or volcanic arc mountain ridges on the surface when the sinking oceanic plates melts.
Other features formed along tectonic plate boundary include: OCEAN TRENCHES, ISLAND ARC, SUBMARINE MOUNTAIN RANGES, and some others.
Therefore, only numbers 1, 4 and 5 are correct.
