Many others combine the two continents North America and South America into one and call it the American continent. Eventually as the processes of plate tectonics continues some the island arcs may have crashed into each other forming even bigger land masses. While the southern portion of the continent, in the southern United States and Central America, is subtropical, the northern portion of the continent consists largely of Arctic tundra. This ocean is considered to be the youngest of all oceans, geologically. It contains giant oil and gas fields and valuable minerals as well. The only human presence in Antarctica are scientists who live on the island on a temporary basis. Officially known as the Commonwealth of Australia, the country is an Oceanian country.
Berkeley: University of California Press. In many parts of Europe, students are taught that there are only six continents, and teachers count North and South America as one continent. You can also divide the earth's major landmasses into tectonic plates, which are large slabs of solid rock. The driest place on earth is the Atacama Desert in Chile. High winds, extremely cold temperatures, lack of vegetation, and a very dry desert makes the climate of Antarctica highly inhospitable. The World Wars were both concentrated around Europe, and that led to a decline in the dominance of the continent in world affairs by the time the world came on to the 20 th century.
This divides the entire land surface of Earth into continents or quasi-continents. Average temperatures in the Antarctic interior get down to -70 degrees Celsius during the winter months and -35 degrees Celsius in the warmer months. The coasts and offshore waters, however, are home to penguins, petrels, fulmars—sea birds—and other marine mammals. Indian Ocean is also rich in exotic plan and animal species. The partial melting of the andesitic crust produced magmas that were andesitic to granitic in composition. So, this sinking slab of lithosphere would have also absorbed a significant amount of water. The temperature here is known to have reached -89 degrees as well.

Now, one of the interesting results partially melting rocks is that you end up with a magma that has a slightly different composition than the parent rock. Africa is the world's second largest continent and also the hottest. Antarctica is the smallest continent by population numbers. Unlike the other continents, it contains only one country, which is Australia. North America has been inhabited for thousands of years but was discovered by Europeans in 1492 through a voyage undertaken by Christopher Columbus.
Many people combine the two continents Asia and Europe into a single continent and call it Eurasia. Here, North and South America are considered to be one single continent of America. Saudi-Arabia, the United Arab Emirates and Bahrain are also among richest countries in the world due to their oil reserves. However, they may also be viewed as a single continent known as America or the. Support Kids Learning Tube by becoming a Patreon today at the link below! The Ural and Caucasus Mountains are generally thought to be the eastern boundary of Europe. The deepest point in the ocean is the Like Deep in the Eurasian Basin.
Europe is divided from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian Sea, black sea and the waterways connecting black sea and Aegean Sea. Let us learn about each of these seven continents and five oceans that make up our planet earth. Terra Cognita: The Mental Discovery of America. Southern 20,327,000 sq km 5. Only cold adapted organisms have the capacity to survive in this continent. About 50% of the residents in the continent are younger than 19 years of age. New York: Oxford University Press; p.
The far south regions and the interior regions are just sparsely populated. The main languages are English, Spanish, and French. Eventually it got dense enough that it could sink back into the mantle. In order to understand where the continents came from we have to go back to about the beginning. Indian Subcontinent The Indian subcontinent is situated in South Asia.
This water reduces the melting point of the rocks causing the to partially melt. The fourth largest continent is South America, and the fifth largest continent is Antarctica. Retrieved 14 January 2007, from Encyclopædia Britannica Online. Asia and Africa are joined by the , and North and South America by the. New York: Oxford University Press. The oldest fossils of Homo sapiens found till now have been from the eastern parts of this continent.
As a , the concept of a continent may go beyond the continental shelf to include and continental fragments. There are many , that are built of continental crust but do not contain a craton. By the year 1900, Europe contributed to about 25% of the total world population. But for us, the small living beings on this planet, this is a very huge home. About 75% of the Russian population lives in the European continent. Arctic Ocean lies mostly in the Arctic Circle. Asia is also home to the most languages in the world, over two thousand from popular Mandarin to Javanese.
