Question

which statement best describes the illustration? a trench forms at a transform boundary a rift valley forms at continental - continental convergence boundary a volcano forms at an oceanic - oceanic convergence boundary. a mountain forms at a divergent boundary

Explanation:

Trenches form at convergent boundaries, not transform boundaries. Rift valleys form at divergent boundaries, not continental - continental convergence boundaries. Mountains form at convergent boundaries, not divergent boundaries. Volcanoes commonly form at oceanic - oceanic convergence boundaries where one oceanic plate subducts beneath another, melting occurs, and magma rises to form volcanoes.

Answer:

C. A volcano forms at an oceanic - oceanic convergence boundary.
