Hemisphere
1 answer
A hemisphere is a term used in geometry to describe half of a sphere. It is a three-dimensional object that has a curved surface and a circular base. The term "hemisphere" is derived from the Greek words "hemi," meaning half, and "sphere," meaning a perfectly round object. Hemispheres can be found in various sizes and are used to describe various objects in science, geography, and mathematics. For example, the Earth can be divided into two hemispheres: the Northern Hemisphere and the Southern Hemisphere, which are divided by the equator. Similarly, the brain is often divided into two hemispheres: the left hemisphere and the right hemisphere, which control different functions of the body.
