Antarctica (pronounced /ænˈtɑrtɨkə/ or /ænˈtɑrktɨkə/ ( listen))[2][3][Note 1] is Earth’s southernmost continent‚ encapsulating the South Pole. It is situated in the Antarctic region of the Southern Hemisphere‚ almost entirely south of the Antarctic Circle‚ and is surrounded by the Southern Ocean. At 14.0 million km2 (5.4 million sq mi)‚ it is the fifth-largest continent in area after Asia‚ Africa‚ North America‚ and South America. For comparison‚ Antarctica is nearly twice the size of Australia.

largest continent on this planet‚ this giant freezing mass is place over the South Pole with a total surface area of about fifteen million square kilometers. However‚ this figure fluctuates depending on the season‚ for example; it is approximately fourteen and a half million square kilometers in the summer. Yet compared to other continents such as the United States‚ it’s shy of almost half as big. Divided into two major areas‚ which are: East Antarctica and Western Antarctica‚ this continent is predominantly

that the ratio of continents‚ compared to the ocean‚ was so much smaller than it is now. In figure 2‚ (graph a) the continent fraction of the Earth’s surface as a function of time shows that the continents at first were a small ratio compared to the ocean. It also reveals that as time progressed‚ the continents began to grow and so did the albedo. Graph b shows the surface albedo of the earth as a function of time‚ which verifies that the albedo indeed does increase as the continent fraction also begins

It is a continent of such Geographical diversity that no one can claim to apprehend genuinely. Most of the Traditional African Diets are the same as today’s diets in African continents.

this ended‚ the Earth cooled and its surface solidified to a crust - the first solid rocks. There were no continents as yet‚ just a global ocean peppered with small islands. Erosion‚ sedimentation and volcanic activity - possibly assisted by more meteor impacts - eventually created small proto-continents which grew until they reached roughly their current size 2.5 billion years ago. The continents have since repeatedly collided and been torn apart‚ so maps of Earth in the distant past are quite different

continental drift? Wegener noticed that the continents seemed to fit together‚ not at the continuously changing shoreline‚ but at the edge to their continental shelves. He derived this hypothesis from the observation that the continents in the southern hemisphere exhibit an identical pattern of rock and fossils known as the "Goodwin sequence". The most logical explanation was that the continents themselves were once parts of a much larger "super-continent" which was named Pangaea. A second idea

most westerners have a negative view on Africa‚ but a completely misunderstood point of view on Africa. Africa is a beautiful continent with fascinating cultures and amazing people‚ yet most of the western world fails to see the beauty that is Africa. Based on Ann Jones’s novel‚ most westerners have a misconception about Africa‚ and view it as unhealthy‚ a dark continent‚ unimportant to history‚ and unresourceful. Most westerners believe that all of africa is aid ridden and disease stricken‚ but

African continent both in the pre colonial and the colonial era. The scourges of slave trade‚ inter-tribal warfare and more importantly the imposition of colonial rule on the people of Africa made peace and stability on the continent quite elusive. Obviously‚ one would foresee emancipation and independence as a sure way to relative peace and stability. Unfortunately‚ the post-colonial conflict situation on the continent has proven more disturbing than ever in the history of the continent. The formation

like a puzzle and the continents look like the pieces that would fit together to complete the puzzle. In 1912‚ Alfred Wegener‚ a German scientist and an adventurer‚ came up with a theory that the continents had once been part of a "supercontinent". Wegener proposed that‚ over 200 million years‚ what he called Pangea had separated and became individual pieces. Pangea means "all lands" in Greek‚ and that is what Pangea was‚ a very large landmass when all of the continents were connected. When
