Question

Do large bodies of water (oceans) curve perfectly with the curvature of the Earth?

In: Physics

Answer 1

if you have a giant ocean sized pool, suspended and isolated from other vibrations and forces (like the moon) other than Earth’s gravity itself then yes, the water will perfectly follow the curvature of the earth.

but because we cant do that obviously. when you take into consideration things like the moon causing tides, winds, and underwater earthquakes, the water is not going to perfectly match the Earth’s curve almost ever.

side note, i would be willing to bet that if you took the AVERAGE potion of all the major bodies of water relative to the average curve of the earth, it would be pretty consistent.
