The Earth is geoid THE EARTH IS SPHERICAL
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
The circumference of the earth at the equator is 40,075.16 kilometers or 24,901.55 miles.The shorter circumference of the earth over the poles is 40,007.86 kilometers or 24,859.73 miles.The difference is 67.3 kilometers or 41.82 miles.This shape is known as an ellipsoid or more properly, a geoid (earth-like).
The diameter (Breadth) of the earth at the equator is 7,926.41 miles (12,756.32 kilometers). But, if you measure the earth through the poles the diameter is a bit shorter - 7,901 miles (12,715.43 km). Thus the earth is a tad wider (25 miles / 41 km) 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).

The Earth is geoid THE EARTH IS SPHERICAL
The geoid is an equipotential surface that represents mean sea level around the Earth, taking into account the planet's gravitational field and rotation. It serves as a reference for measuring elevation and is used in creating precise global height models for applications like GPS systems and geodesy.
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.
The technical name for the shape of the Earth is geoid. This is studied in the science of geodesy.
"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.")
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.

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
