Question

multiple answer 1 point what geological features can be formed at oceanic crust boundaries? deep ocean trench mid - ocean ridge rift valley mountain range volcanic island arc volcanic arc

Explanation:

Geological features at oceanic crust boundaries result from plate tectonic activities. Deep ocean trenches form at convergent boundaries (subduction); mid-ocean ridges and rift valleys at divergent boundaries (seafloor spreading); volcanic island arcs at oceanic-oceanic convergent boundaries. Mountain ranges typically form at continental boundaries. Volcanic arcs can include continental, so not specific to oceanic.

Answer:

deep ocean trench, mid-ocean ridge, rift valley, volcanic island arc
