Answer 2

Hemi=half

Sphere = basically, a ball. A basketball is a sphere--but no one ever talks about half of a basketball. Earth is a sphere, too.

Hemispheres also refer to the two halves of the brain:
"How many brains do you have - one or two? Actually, this is quite easy to answer...you have only one brain. However, the cerebral hemispheres are divided right down the middle into a right hemisphere and a left hemisphere. Each hemisphere appears to be specialized for some behaviors. "

Answer 4

A hemisphere is a half of a sphere, where a sphere is a three-dimensional object that is perfectly round in shape, with all points on its surface equidistant from its center. To remember the definition, you can break down the word "hemisphere" into two parts: "hemi-" means half, and "-sphere" refers to a round object like a ball. So, a hemisphere is literally "half a sphere."
