The majority of the ocean basins on Earth were created by either subduction or seafloor spreading, two types of plate tectonic activity. ","acceptedAnswer": {"@type": "Answer","text": "In fact, the reason the continents are so much older than the ocean floor is that the continental crust is composed of material too light to sink into the mantle. Ocean basins form in the beginning by stretching and splitting (rifting) of continental crust, and the increase of mantle fabric and magma into the crack to form new oceanic lithosphere. These plates move very slowly and meet at their boundaries. f Stage 1 is Embryonic, continental drifting plays a big role in the formation of an ocean, rift valley forms as continent begins to split when the separation occur sediments from the adjacent continents soon begin to build out to the new How To Add Sea Blue-Green To Your Color Palettes?
