  • The geoid represents the mean sea level of the Earth, serving as a reference for measuring elevations.

Examples

  • But but this is relative to the geoid, relative to a constant level surface on the ocean.

  • Scientists rely on the geoid to ensure accurate measurements for sea-level changes and ocean currents.

  • Understanding the geoid is essential for geographers who analyze the Earth's gravitational field and surface features.

Morphology

geoid = geo + oid (semi-transparent) = geo + oid

The parts suggest something earth-shaped, but the technical geodesy sense is not fully predictable for an average B1 learner.

Etymology

Geoid comes from the Greek parts geo- meaning 'earth' (as in geography) and -oid meaning 'like' or 'shape' (as in asteroid). So a geoid is an 'earth-like shape' — the real, slightly uneven shape of the Earth that shows mean sea level and is used to measure heights and ocean depths.
