what is the definition of hemisphere i need something easy to remember
hemi = half
sphere = earth
hemisphere = half the earth
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. "
