The oceans floor doesn't just keep getting wider instead the ocean floor plunges into deep underwater canyons called deepocean trenches.Where ever deep ocean trenches are there is subduction.
The ancient oceans changes were made from the continental shift. The sea floor crusts and ground formations constantly moved and created deep canyons at the bottom of the oceans.
The deepest parts of the ocean floor are caused by plate tectonic subduction and occur where the sea floor sinks back into the mantle in a subduction zone. These areas are called deep sea trenches and the Challenger Deep in the Mariana Trench in the Pacific is the deepest known point in Earth's oceans.
