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.


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 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 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 is called the true model of the Earth?

The true model of the earth would be called an oblate spheroid. The earth is close to spherical, but bulges a little around the middle (equator). There is also a term for the theoretical 'average earth' if you will, that is the best possible fit between mathematical model and the actual physical planet. It is called the geoid. Surface altitude is calculated for a given spot based not on the physical earth, but on the location of the theoretical geoid at that spot.


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.


The earth is a perfect sphere?

No, the Earth is a bit wider than it is "high". The shape is often called a geoid (Earth-like) or an ellipsoid. The rotation of the Earth causes a slight bulge toward the equator. The circumference of the Earth at the equator (24,901.55) is about 41 miles greater than the circumference through the poles (24,859.82 miles. If you were standing on the moon, looking at the Earth, it would be virtually impossible to see the bulge and the Earth would appear to be a perfect sphere. The mathematical name for the shape of the earth is an 'Oblate spheroid'.


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
