The entire continent and most of its associated islands are within the Southern Hemisphere. From the Equator (Latitude: 0°) to Bishop and Clerk Islets, Tasmania, Australia (Latitude: 55°03′ S). South America Most of the continent, from south of the Amazon River mouth in Brazil in the east to north of Quito in Ecuador in the west.
Northern Hemisphere: The half that lies north of the Equator. This hemisphere contains approximately 68% of Earth's landmass and is home to about 90% of the global population. [4] It includes North America, Europe, Asia, and most of Africa. Southern Hemisphere: The half that lies south of the Equator. It contains approximately 32% of Earth's ...
The plane of Earth's equator, when projected outwards to the celestial sphere, defines the celestial equator. In the cycle of Earth's seasons, the equatorial plane runs through the Sun twice a year: on the equinoxes in March and September. To a person on Earth, the Sun appears to travel along the equator (or along the celestial equator) at ...
The 45th parallel north is often called the halfway point between the equator and the North Pole, but the true halfway point is 16.0 km (9.9 mi) north of it (approximately between 45°08'36" and 45°08'37") because Earth is an oblate spheroid; that is, it bulges at the equator and is flattened at the poles.

Asia Americas Europe; About two-thirds, from north of Libreville in Gabon in the west to south of Mogadishu in Somalia in the east. The entire continental mainland. Part of Indonesia, and 24 out of 26 atolls of Maldives in the Indian Ocean, are also in the Northern Hemisphere. All of North America, Central America, and the Caribbean islands.
The northern one is called the Tropic of Cancer, and the southern is the Tropic of Capricorn. As the Earth's axial tilt changes, [a] so too do the tropical and polar circles. The tropics constitute 39.8% of Earth's surface area [1] and contain 36% of Earth's landmass. [2]
North of the tropic are the subtropics and the North Temperate Zone. The equivalent line of latitude south of the Equator is called the Tropic of Capricorn, and the region between the two, centered on the Equator, is the tropics. In the year 2000, more than half of the world's population lived north of the Tropic of Cancer. [4]
The 16th parallel north is a circle of latitude that is 16 degrees north of the Earth's equatorial plane. It crosses Africa , Asia , the Indian Ocean , the Pacific Ocean , Central America , the Caribbean , and the Atlantic Ocean .
