Continents in the world are the large land masses that we see.
Our earth is made up of large land masses known as continents and water bodies known as oceans. The earth has not been like this always as how we see it now. Millions of years before there were only one large land mass and a large ocean surrounding it. Later on, the land mass started to split and drift apart surrounded by ocean on all sides. This process is still going on. Now we have 7 continents in the world and 5 oceans which are home to all of us and millions of other living organisms. Let us learn about each of these seven continents in the world and five oceans that make up our planet earth.
Asia is the largest world continents in the world covering about 9 percent of the earth. It is also the most populated continent on earth, home to an estimated population of around 4.3 billion people. This large population makes it an important part of the world economy.
Africa is the second largest continent in the world. It is also the second in terms of population among world continents. Africa is commonly referred to as the black continent by many. This large land mass comprises of 54 countries and is home to one billion people.
North America is a continent which lies wholly in the northern hemisphere. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the east, the Pacific Ocean to the south and west, and South America and the Caribbean Sea in the southeast. North America lies almost wholly in the western hemisphere. North America covers almost 4.8 percent of the earth’s surface and comprises around 16.5 percent of the whole land area on earth. North America is home to nearly 565 million people.It is the third largest among world continents by area and fourth largest continent by population.
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 the Pacific Ocean on its western side, the Atlantic Ocean in the north and eastern side, and North America and the Caribbean Sea in the North West side. With an area covering 17,840,000 square kilometers and a population of more than 3 billion, South America is the fourth largest among other world continents in terms of size and fifth in terms of population. South America is home to twelve sovereign states and two non-sovereign states. It is generally considered to be a subcontinent of the Americas.
Antarctica is the southernmost continent of all, Antarctica is the fifth largest among the seven continents.The geographic south pole of the earth is contained in this continent. It is made of large permanent glaciers that surround the South Pole. This is one of the most uninhabitable places on earth. Antarctica is the least populated continent on earth. It is also home to very few plant and animal species. Antarctica is also the polar landmass on earth and much of this continent is made of permanent glaciers. Around 98% of the continent is covered by ice of about 1.9 kilometers thick.
Europe is the second smallest continent in the world. It comprises the westernmost peninsula of the giant Eurasian landmass. Covering almost 2 percent of the earth’s surface Europe takes 6.8 percent of the world’s total land area. Europe is home to almost 50 countries and is the third most populated continent in the world after Asia and Africa.
Australia is a single country continent. It is the sixth largest country by total area and is also the smallest of all the seven continents. Because of its size, and isolated location, it is also called as an island continent. Covering an area of 7617930 square kilometres, Australia lies in the Indo- Australian Plate. This continent is surrounded by the Indian Ocean and the Pacific Ocean. Australia is one of the least populated continents and is rich in biodiversity.
