You'll have to explain this argument further, as it doesn't follow.
A horizon (to the visual eye ,looks like the water is meeting the sky or the water is dropping off.
No matter which ocean you visit or sea which has more than so many miles of straight ahead view of water, you'll always notice the horizon or ( the end of the world as they use to put it in the old days, where you don't see no more water, but yet it is there) always appears to look the exact same distance where the water looks as if it drops off or meets the sky.
This is because your starting to see the earths curvature.
añd this is how it is in every ocean around the world.
Which means the earths shape is pretty much round all the way round. It's why the tide on seas drifts in and out. Because the earth is spinning.
The weight load of the body of water falls one way then the other as the globe spins.
Pretty basic to explain really
