The continent is compact and roughly triangular in shape, being broad in the north and tapering to a point—Cape Horn, Chile—in the south. South America is a continent located in the western hemisphere with most of its land area lying in the southern hemisphere and a relatively small portion in the northern hemisphere. It has Pacific Ocean to its western side, Atlantic Ocean in the north and eastern side, and North America and Caribbean Sea in the North West side. The Southern Ocean, also known as the Antarctic Ocean is an enormous body of water that surrounds the entire continent of Antarctica and reaches Australia and the southern end of South America. This cold part at the top is my most northern point and is called the North Pole. This supercontinent was Gondwana. It marks the difference between my two parts: the northern hemisphere and the southern hemisphere. Earth is divided into a Northern and Southern Hemisphere at the Equator, the imaginary line on the planet midway between its geographical poles. This ocean is a smaller body of water compared to the Pacific Ocean , Atlantic Ocean and Indian Ocean but is bigger than the Arctic Ocean. Gondwana comprised the southern half of this supercontinent. The Southern Hemisphere contains all or parts of five continents, including all of Antarctica, Australia, almost all of South America, the southern third of Africa and some southern islands in Asia (parts of Indonesia). The Southern Hemisphere is the half sphere of the Earth which is south of the equator. The 7 continents of the world are North America, South America, Antarctica, Europe, Asia, Africa, and Australia. The concept that all of the continents of the Southern Hemisphere were once joined together was set forth in detail by Alfred Wegener, a German meteorologist, in 1912. Gondwana's breakup Most of South America and about half of Africa is in the southern hemisphere as well. Terra Australis (Latin for South Land) was a hypothetical continent first posited in antiquity and which appeared on maps between the 15th and 18th centuries. With 5.4 million square miles it is about 1.3 times as large as Europe. The 5 oceans of the world are the Atlantic Ocean, the Indian Ocean, the Pacific Ocean, the Southern Ocean, and the Arctic Ocean.. One of the most fascinating scientific topics is the study of the 5 oceans and 7 continents. The Northern Hemisphere refers to the half of the planet that is north of the equator, while the Southern Hemisphere is all of the planet south of the equator. He envisioned a single great landmass, Pangaea (or Pangea). Some continents run through both hemispheres, although all of Europe and North America are in the Northern Hemisphere. It also includes four oceans (Indian, South Atlantic, Southern and South Pacific) and a major part of Oceania. The southern landmass, still carrying all those bits and pieces of the future southern hemisphere, headed southward after the split. South America, fourth largest of the world’s continents. The existence of Terra Australis was not based on any survey or direct observation, but rather on the idea that continental land in the Northern Hemisphere should be balanced by land in the Southern Hemisphere. The continents of Australia and Antarctica are entirely in the southern hemisphere. Being the Earth’s southernmost continent located in the Antarctic Region of the Southern Hemisphere, it contains the geographic South Pole. The fifth largest continent is Antarctica. It is the southern portion of the landmass generally referred to as the New World, the Western Hemisphere, or simply the Americas.
