You know that there are 7 continents(6 if you were taught geography in Europe) right now, but do you really know the definition of what is a continent? There are many different, and confusing definitions of what a continent is. The most widely accepted one says that a continent is defined as a large, continuous, discrete mass of land, ideally separated by an expanse of water. This definition somewhat confuses things. Many of the current continents are not discrete landmasses separated by water. The word large leads to arbitrary classification: Greenland, with a surface area of 2,166,086 km2 is considered the world’s largest island, but Australia with a land mass of 7,617,930 km2 is a continent. The qualification that each be a continuous landmass is disregarded because of the inclusion of the continental shelf and oceanic islands and is contradicted by classifying North and South America and Asia and Africa as continents, without a natural separation by water. This idea continues if the land mass of Europe and Asia is considered as two continents. Also, the Earth’s major landmasses are surrounded by one, continuous World ocean that has been divided into a number of principal ‘oceans’ by the land masses themselves and various other geographic criteria.
The people from south and central america are dumb. There are 7 continents not 5. Doesn't matter what is on the Olympic flag...the greeks thought that the earth was flat and that the sun was brought across the sky by a guy on a chariot. THEY ARE WRONG AS ARE YOU. United Stadians ( my new term to distinguish us that live in the us from other "Americans") invited machines that defy gravity, tele communication, and all sorts of other baller ****. you guys are poor and dumb, go eat some rice its all you can afford.
