What is the actual shape of the earth? Why is it shaped that way?

Answer 1

It is a sphere.

The laws of motion and gravity work together to form the spherical shape of all large spinning objects in the universe. Gravity pulls an object's mass towards its center at a constant rate, and as the object spins, gravity keeps the matter together and moving in a circular path.

Oblate Spheroid

It looks like circular on the side and almost flat on the poles.

It is near oblong and slightly spherical, this is caused by the rotation of the earth. So when the Earth rotates, the tendency of the Earth is to bulge in the middle (equator).

This is an oblate spheroid. This is the shape of the earth. (Never mind the red lines:)

Answer 3

Levi Alexander

Although gravity pulls the Earth's mass into a roughly spherical shape, the rotation causes it to flatten slightly at the poles and bulge at the equator, giving it its oblate spheroid shape. The actual shape of the Earth is an oblate spheroid, meaning it is mostly spherical but slightly flattened at the poles and bulging at the equator.

Answer from HIX Tutor

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
