The division of Earth by the Equator and the prime meridian Map roughly depicting the Eastern and Western hemispheres. In geography and cartography, hemispheres of Earth are any division of the globe into two equal halves (hemispheres), typically divided into northern and southern halves by the Equator and into western and eastern halves by the Prime meridian.
Also narrow.

The land hemisphere and water hemisphere are the hemispheres of Earth containing the largest possible total areas of land and ocean, respectively. By definition (assuming that the entire surface can be classified as either "land" or "ocean"), the two hemispheres do not overlap. Determinations of the hemispheres vary slightly.
Northern Hemisphere from above the North Pole. The Northern Hemisphere is the half of Earth that is north of the equator. For other planets in the Solar System, north is defined by humans as being in the same celestial hemisphere relative to the invariable plane of the Solar System as Earth's North Pole. [1]
The Americas, also known as America, [1] are lands of the Western Hemisphere, composed of numerous entities and regions variably defined by geography, politics, and culture. The Americas are recognized in the English-speaking world to include two separate continents : North America and South America .
The almost perfect circle (the earth is an oblate spheroid that is wider around the equator), drawn with a line, demarcating the Eastern and Western Hemispheres must be an arbitrarily decided and published convention, unlike the equator (an imaginary line encircling Earth, equidistant from its poles), which divides the Northern and Southern hemispheres.
The highest mountain in the Western Hemisphere is Aconcagua in the Andes of Argentina at 6,960.8 m (22,837 ft). [13] The tallest freestanding structure in the Western Hemisphere is the CN Tower in Toronto at 553.3 m (1,815 ft) and the tallest building in the Western Hemisphere is One World Trade Center in New York City at 541.3 m (1,776 ft).
This is placed in a machine which molds the disk into a hemispherical shape. The hemisphere is united with its opposite counterpart to form a complete globe. Usually a globe is mounted so that its rotation axis is 23.5° (0.41 rad) from vertical, which is the angle the Earth's rotation axis deviates from perpendicular to the plane of its orbit.
