Atlantic rift is spreading fastest.

The Pacific slowest.

Answer 2

The Atlantic ocean and the Arctic ocean are a good examples of active, growing oceanic basins, whereas the Mediterranean Sea is shrinking. The Pacific Ocean is also an active, shrinking oceanic basin, even though it has both spreading ridge and oceanic trenches. Perhaps the best example of an inactive oceanic basin is the Gulf of Mexico, which formed in Jurassic times and has been doing nothing but collecting sediments since then. The Sea of Japan and Bering Sea are also good examples of inactive oceanic basins.
