WebJun 26, 2024 · Explanation: The indication that the plate is spreading or splitting apart is the the formation of Rift Valleys and Oceanic Ridges. Divergent plate boundaries are mostly situated in along underwater mountain ranges called Oceanic ridges. Once the plate separated, new materials from the mantle appears and fill up the gaps, producing new … WebRift- Valleys can be formed when plate motion starts to stretch the lithosphere, at the same time plums of hot rock rise from the mantle. The rising plums bend the crust upward, weakening and fracturing it. . The fractures allow magma to the surface, resulting in the new floor called a rift valley.
