hemisphere
Half a sphere
A hemisphere is half of a sphere—any globe-shaped object divided in two.
Most commonly, the word refers to halves of Earth: the Northern and Southern Hemispheres (divided by the equator) or the Eastern and Western Hemispheres.
In anatomy, the brain's two cerebral hemispheres control opposite sides of the body: a stroke in the left hemisphere.
