As much as 70% of the surface of our planet is occupied by water, the remaining 30% is land, the area of which is 149 million km 2. Half of this territory is occupied by only 10 countries, while there are at least 206 different states on the planet. It is these giants in terms of area and population that make up the list 10 largest countries in the world.
The largest state on the African continent and the first on our list is the Algerian People's Democratic Republic. It occupies 2.381 million km 2 and this is largely due to the Sahara Desert, which is part of the country. Algeria produces large quantities of oil and gas, but 17% of the country's residents live in poverty, which indicates a less than conscientious government. In summer the temperature exceeds +50 degrees, but snow is possible in winter. It has an ink lake within its borders - there is nothing else like it in the world.
9. Kazakhstan
Among the 10 largest countries in the world by territory is Kazakhstan, a country that has incredible flavor. Its residents still diligently preserve the traditions of past years and are noted for their enviable hospitality. As in the vastness of Algeria, they are engaged in gas and oil production. State area: 2.724 million km 2. Among other giant countries, Kazakhstan is the only one landlocked, but has its own internal Aral Sea, as well as the inexplicable Lake BalKhash, the first half of which consists of fresh water, and the second of salt water.
8. Argentina
Occupying 2.766 million km 2, Argentina is famous throughout the world primarily for two legendary football players - Maradona and Messi, both of whom at one time became winners of the Golden Ball. It was named after the metal – silver, but in the end there wasn’t very much of it in its depths. It is a recognized fact that this is where the longest street in the world is located; the number of houses exceeds twenty thousand. Argentina stretches from north to south, so it lies in several climatic zones. And if its northern part is subtropical, then its southern part is deserts with incredibly cold weather conditions.
India's population is 1.2 billion people, which immediately puts it in the top 10 largest countries in the world. It occupies an area of 3.287 million km 2, but in economic terms it is still sagging. However, it is considered the most promising for development in the future. Before the arrival of the British, who made India their colony, the country was listed as one of the richest in the world. This is where Columbus wanted to get, but he sailed to America. Named after the Indus River, it is widely known as the birthplace of spices, Buddhism and tea.
6. Australia
It is an entire continent, occupying 7.686 million km 2. Most of the land is uninhabited and unsuitable for living, and the population is correspondingly not high. But at the same time, the mainland is home to many unusual species of animals and plants that are found only here. Australia also includes many nearby islands; the capital is Canberra, the most populated city. Among the key problems is the small number of fresh water sources, since the majority of water bodies are salty.
5. Brazil
In the list of the 10 largest countries in the world by area, one cannot do without the leader of South America in territorial terms. Hot Brazil is famous for football, carnivals and huge coffee plantations. Part of the country is occupied by a huge jungle, as well as the largest river in the world - the Amazon. Thanks to its location, the state managed to border on all the countries on the mainland. Due to its close connection with Portugal, Catholicism predominates here, making Brazil the country with the largest Catholic population.
Statistics show that at the moment every sixth inhabitant of the planet is Chinese, because the number of people in the country will soon exceed 1.4 billion. In this regard, China is the largest country in the world in terms of population. It attracts with its unique culture, and also impresses with its achievements, in all areas. Economy, innovation, sports - the state is in a leading position everywhere. Its territory is 9.640 million km 2. China itself consists of four key cities, 22 provinces, and also benefits in size with five more autonomous regions. It has access to the Pacific Ocean and borders immediately with 14 countries on the Eurasian mainland.
An area of 9.826 million km 2 puts the United States of America in third place, despite the endless desire to be a leader in everything. The economy of this country is considered one of the most impressive in the world. Baseball and fast food were invented here, but, unfortunately, it is in the USA that the largest number of tornadoes occur per year, which constantly cause significant destruction. Includes 50 states, each of which has its own unusual flavor or lifestyle. It borders only three countries, Mexico and Canada, and also, thanks to a small part separated from the country in the very north, also with Russia.
In terms of area, Canada has not gone so far from the previous country, which is its neighbor, it occupies 9.976 million km 2. At the same time, it would never be in the top 10 largest countries in the world by population, because it wins only by its territory, but not by the number of people, of whom only 34 million live here. A very low figure, but it does not affect the development of the country. Canada is rightly called the land of lakes; there are an incredible number of them here and many of them are among the top 10 largest in the world. Among them, Medvezhye and Verkhneye are the largest among fresh ones.
The undoubted leader - this country occupies 17.075 million km2, which is almost twice as much as its closest pursuer. Russia is rich in various minerals and resources, neighbors 18 countries and has the greatest extent, because while on one edge people go to bed, on the other they are already getting up for work. In its vast expanses it has more than a hundred different rivers, and the number of reservoirs exceeds the 2 million mark. It is also famous for Lake Baikal, which is the deepest lake on the planet. The highest point in the country is Mount Elbrus, its height is 5.5 km.
Each country is ranked in three categories: area, population and economic development.
