Why is it not helpful to use the term geoid to describe the shape of the earth?

The geoid has an equipotential surface where the force of gravity is perpendicular everywhere. But the earth has an irregular mass distribution and the resultant anomalies, makes the term geoid not a suitable reference.

What is a ellipsoid?
an ellipsoid is the less formal name for a geoid which is a shape which is like a sphere but is bulgy round the middle
Is the earth's shape a perfect circle?
No, a circle is a two-dimensional shape, whereas the Earth has three-dimensions. Many people assume Earth is a sphere, however the Earth is wider at the equator than it is tall at the poles. This shape is described as an oblate spheroid.
What shape are the sun earth and earth and other planets?
Approximately spherical, but because of the speed of their rotation, there is certain 'oblateness' - a little flattening of the shape on the poles. The shape that results is often called a 'geoid'.
What is earths diameter?
The diameter of the earth at the equator is 12,756.32 kilometers or 7,926.41 miles.The diameter of the earth through the poles is 12,715.43 kilometres or 7,901.00 miles.Thus the earth is 59 km or 25 miles wider than it is tall, giving it a slight bulge at the equator.This shape is known as an ellipsoid or more properly, geoid (earth-like), or oblate spheroid (squashed sphere).
What is the diameter of earth from the sun in miles?
The diameter of the earth at the equator is 12,756.32 kilometers or 7,926.41 miles. The diameter of the earth through the poles is 12,715.43 km or 7,901.000 miles. Thus the earth is 41 km or 25 miles wider than it is tall, giving it a slight bulge at the equator. This shape is known as an ellipsoid or more properly, geoid (earth-like).
Shape of earth geoid or spherical?
The Earth is geoid THE EARTH IS SPHERICAL
What is the geoid of the earth?
a geoid is shape or sphere etc.
What is an earth-shaped object called?
The technical name for the shape of the Earth is geoid. This is studied in the science of geodesy.
How would you describe the earths shape?
the shape of the earth is not flat. it has a spherical shape. its slightly flattened at the poles to give a nearly spherical shape hence; the earth's shape is better described as a geoid which means the earth's shape
What are earths most likely forms?
"Roundish" is the clear winner so far as I know.(The actual shape of Earth is not a sphere; it's a "geoid", but saying "Earth is a geoid" is pretty much a tautology, since it amounts to saying "Earth is Earth-shaped.")
What is earth called as?
The shape of the earth, after the unevenness of the mountains and valleys have been removed, is geoid. This, rather unhelpful term means earth-shaped. The geoid represent the shape that would be attained by the earth's oceans in the absence of tides and currents; and which is them extended onto the continents. It is the baseline which identifies the mean sea level.A simpler term is an oblate sphere. These is a flattened sphere.Simplifying even more, the earth may be referred to as a sphere.
How do the following ancient people describe the shape of the earth?
the ancient people describe the shape of the earth as a coin.they beleive that the earth is flat like a coin.
Briefly describe the shape of the earth?

What is an earth shaped object called?
The technical name for the shape of the Earth is geoid. This is studied in the science of geodesy.
How would you describe the shape of the earth?
a sphere or 3D circle
What shape best describe the earth?
a slightly squashed sphere.
What is a ellipsoid?
an ellipsoid is the less formal name for a geoid which is a shape which is like a sphere but is bulgy round the middle
