Geoid is the ________ of earth.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. shape.
The geoid is the shape of the Earth that represents its mean sea level extended across the continents. It is a theoretical shape that accounts for variations in Earth's gravitational field, reflecting the irregularities caused by the planet's uneven distribution of mass. The geoid is used as a reference surface for measuring elevations and sea levels and serves as a model to understand Earth's gravitational potential more accurately. It differs from the idealized shape of a sphere or ellipsoid used in simpler models.
