The hypothetical area of this planet that coincides every-where with mean sea level.

The hypothetical surface of this earth that coincides every-where with mean sea level.

A surface of continual gravitational possible at zero elevation.

A surface of constant gravitational possible at zero level.

An imaginary area which coincides with all the mean sea-level throughout the ocean, and extends underneath the continents every-where at that degree at which the mean area regarding the water would remain if it had been permitted to flow in through a tiny subterranean channel.

An imaginary surface which coincides with the mean sea-level across sea, and expands underneath the continents everywhere at that amount from which the mean surface for the water would stand if it had been permitted to move in through a small subterranean channel.

The hypothetical area for the earth that coincides every where with mean sea-level.

A surface of continual gravitational potential at zero elevation.

An imaginary surface which coincides utilizing the mean sea-level over the ocean, and runs in continents everywhere at that amount from which the mean area associated with the water would stay if it had been permitted to move in through a tiny subterranean canal.

See geode.

The hypothetical surface regarding the planet that coincides every where with mean sea-level.

A surface of continual gravitational prospective at zero elevation.

An imaginary surface which coincides using the mean sea-level across ocean, and extends in continents every where at that degree at which the mean surface of the sea would sit if it had been allowed to flow in through a little subterranean channel.
