Question

The radius of the earth is

a. not known.
b. the same everywhere.
c. larger at the poles.
d. larger at the equator.

Answer 1

It is D. Larger at the equator, This is because the Earth isn't a perfect sphere; it bulges around the equator because it's rotating on its axis. The Earth is a flattened sphere, and so the distance around the equator is further than the circumference around the poles.
