We intuitively understand the concept of sea level, but how can it be measured in places that are far from the ocean? The Earth isn't even a regular sphere, so the sea level is different at different places. And then there's the fact that the ocean bulges out more at the equator due to centrifugal force. Add in the question of where would sea level be if there were no land masses -does that enter the equation at all? The technical definition of where sea level is for different places is pretty complicated, but Minute Physics does their best to give us an overview. Aren't you glad there are people dedicated to figuring these things out? -via Viral Viral Videos
