Answer

Brief Explanations:

Trenches are formed at convergent - plate boundaries where the denser oceanic lithosphere subducts beneath the less - dense continental or oceanic lithosphere due to the collision of lithospheric plates. Magma rising is related to volcanic activity at mid - ocean ridges or hotspots. Mantle emerging is not a standard term for trench formation. Volcanoes erupting are a result of magma reaching the surface, not the direct cause of trench formation.

Answer:

lithosphere colliding
