Trench- oceanic-continental convergence
Island arc between trench and continent- oceanic-oceanic convergence
Mountains on “coastal side” of trench- Oceanic-Continental Convergence
Rift valley extending thousands of miles- Divergent Boundary
Mountain range with high plateau on one side- Continental-Continental Convergence
Long linear chain of mountains on seafloor- it's oceanic-oceanic convergence
