Question

example in brief the four hemisphere of the earth
​

Answer 1

Northern and Southern Hemispheres

There are many different ways that the Earth could be divided into hemispheres, but it is usually only divided in two ways. First, the Earth can be separated into Northern and Southern hemispheres by dividing it along the Equator, an imaginary line which runs horizontally around the middle of the Earth. Everything above the Equator is in the Northern hemisphere, while everything below the Equator is in the Southern hemisphere.

Three continents, North America, Europe, and Asia, lie entirely within the Northern hemisphere. The equator cuts across both Africa and South America as well, so parts of those continents also lie in the Northern hemisphere. This is a lot of land. In fact, 68% of the total land in the entire Earth is in the Northern hemisphere. Most of Earth's people, over six billion, also live in the Northern hemisphere. So about 90% of the total global population lives in the Northern hemisphere, with only 10% living in the Southern hemisphere

Answer 2

North–South

Northern Hemisphere, the half that lies north of the Equator

Southern Hemisphere, the half that lies south of the Equator

East–West

Eastern Hemisphere, the half that lies east of the prime meridian and west of the 180th meridian

Western Hemisphere, the half that lies west of the prime meridian and east of the 180th meridian
