In terms of politics, all South American countries are presidential republics except for Peru which is a semi-presidential republic and Suriname, a parliamentary republic.Ībout 70% of Earth’s surface is covered by water. South America relies on the export of manufactured goods and natural resources. The rainforests of the Amazon has made this continent one of the most biodiverse. South America has been home to many interesting species of animals. Indigenous people’s interaction with European conquerors and immigrants was the basis of the continent’s cultural and ethnic outlook. The long history of colonialism, the majority of South Americans speak Spanish. The majority of the population live near the continent’s western or eastern coasts. The population is the 5th amongst the 7 continents at nearly more than 420 million. It is the fourth largest continent with an area of 6.8 million square miles. South America also considered as a subcontinent of the Americas is a continent in the Western Hemisphere, mostly in the Southern Hemisphere with a small portion in the Northern Hemisphere. They have a federal parliamentary constitutional monarchy with two major political groups that form the government. As a small continent, as it is, they have Australia which is the only first-world country having the largest and most dominant economy in the region. Large proportions of Australia belong to no region while Christianity is predominant in those practising faith. Immigration to this continent has brought overseas languages that makeup about 200 that they have. The earliest human migrations including those from out of Africa make up the original inhabitants of the Australian continent. For that, enormous diversity of animal, fungal and plant life have developed. As the rest of the world undergoes significant cooling, Australia has its global cooling effect remain reasonably constant by its gradual movement toward the equator. Its total land area of 3.3 million square miles, it is home to 29 million of the world’s population and biodiversity. Situated in the graphical region in Oceania, Australia is the smallest of the continents. The theories have evolved over the years contradicting each other but however it is called or theorized now, there is no doubt these seven continents have been positioned effectively to support human and animal life. The seven continents Africa, Antarctica, Asia, Australia, Europe, North America, and South America were the product of the Continental Drift. Tectonic plate movements throughout the history of the Earth have caused these super-continents to collide and break into smaller masses of land as continents. Polar researchers have made scientific theories that some million years ago, there were but supercontinents. The 7 continents and 5 oceans were the results of this process that is still ongoing. Events that took place from the earliest single-celled life until the Ice Ages have resulted in that single huge mass of Earth splitting and separating from each other bordered by the bodies of water. As beautiful as it may look now, it has not always been like this. Large masses of land and wide bodies of water known as continents and oceans comprise the environment we have on Earth. Our planet, our mother Earth, despite being like the size of a needle in a haystack in the whole of the universe is home to millions and millions of living creatures big and small. Throughout this lifetime and with the many advances in technology in the field of astronomy, no one has ever been able to spot a planet similar to the diversity as that of our Planet Earth.
