Are the Pacific and Atlantic Oceans at the Same Sea Level?

No. The Pacific’s average sea level is about 125 meters (410 feet) higher than the Atlantic’s. This difference stems from:

• Earth’s rotation: Centrifugal force creates an equatorial bulge; the Pacific sits closer to the equator.
• Basin shape and volume: The Pacific is larger and deeper, exerting greater gravitational pull on its water.
• Landmass distribution: Continents surrounding the Pacific restrict water flow to the Atlantic, raising its level.
