Question

this diagram is a model of earths features at a plate boundary. use the words below to label the features. volcanic island arc deep - sea trench oceanic crust

Explanation:

At a convergent plate - boundary where an oceanic plate subducts beneath another plate, a deep - sea trench forms at the subduction zone. Volcanic island arcs form above the subduction zone due to magma rising from the subducting plate. The thin, dense layer beneath the ocean is the oceanic crust.

Answer:

From left to right (assuming the subduction zone is on the left): deep - sea trench, volcanic island arc, oceanic crust
