Convergent, Divergent, And Transform Boundaries.
Convergent- Oceanic to continental
Where a dense oceanic plate collides with a less-dense continental plate, the oceanic plate is typically thrust underneath because of the greater buoyancy of the continental lithosphere, forming a subduction zone. At the surface, the topographic expression is commonly an oceanic trench on the ocean side and a mountain range on the continental side.
Continental to Continental
Where two continental plates collide the plates either buckle and compress or (in some cases) one plate delves called subduction, under the other. Either action will create extensive mountain ranges.
Ocean to Ocean
When two plates with oceanic crust converge, they typically create an island arc as one plate is subducted below the other. The arc is formed from volcanoes which erupt through the overriding plate as the descending plate melts below it.
