The borders of the state, the great masterpiece of human construction, seem to hide a mysterious force that is determined by the various organizations of our human beings and is closely related to the wonders of nature. Sometimes, a straight river, a majestic mountain range, or a deep ocean can draw the boundaries of a piece of land on a map. And sometimes, the borders that cannot be captured by the naked eye become the dividing line between one country and another. On the map of the world, the size of each country varies greatly. Russia, the giant that straddles the Eurasian continent, is amazed by its vast territory of more than 6.6 million square miles (17,098,242 square kilometers). And the small Vatican City, although only 027 square miles (0.)43 square kilometers), but it has also become the center of Catholicism in the world. Time flies, and the borders of the country are constantly changing in the baptism of time. In fact, as some countries have separated from other countries, many counties have become smaller and smaller. From 76 independent states in 1946, it has grown to 195 in 2023. According to modern estimates, the total area of this world has reached a staggering 196,900,000 square miles (510,072,000 square kilometers). Seventy-one percent of this area is covered by the boundless ocean, and only 29 percent of the land is left standing tall on the blue planet. When we take a closer look at the total area of these countries, we see that this is actually quite tricky. This is because the size of each country depends not only on the land area on land, but also on the continental shelf that extends into the ocean. It's like we're trying to calculate the surface area of a three-dimensional complex geometry that can't be solved by simple addition and subtraction.
Here are the seven largest countries in the world:
Russia, a vast country, deserves the title of the best in the world. It is more than twice as vast as Brazil, which is ranked fifth in the world. This vast land, which occupies one-tenth of the world's land area, spans two continents, spans 11 time zones, and borders 14 countries. It borders the Atlantic, Pacific and Arctic oceans, has about 100,000 rivers, and Lake Baikal, the oldest and deepest lake in the world. Russia's landscapes are vastly diverse, from deserts to mountains to vast deciduous forests. Most of the area is covered by treeless grasslands, which are vast and magical lands known as grasslands and coniferous forests. Magnificent mountains, deep lakes and vast forests make for a rich and varied picture of nature. In this land, many amazing animals live. Snow leopards, polar bears, arctic foxes, Siberian tigers, bighorn sheep and Eurasian brown bears are among the official state animals of Russia. They live freely on this land, adding endless vitality and vitality to Russia. 
Canada, the vast northern hemisphere of art, is a shining emerald, spanning the Atlantic Ocean to the Pacific Ocean, embracing 4,700 miles (7,560 kilometers) of breathtaking scenery. Her silhouette spans six time zones from east to west, showcasing the country's unparalleled multiculturalism. Its northern border clings to the icy Arctic Ocean, while its southern border seamlessly connects with the vast farmlands and bustling cities of the United States. Despite its vast territory, Canada's population is only one-half of the world's population, making it a land of tranquility and harmony. In this vast land, nature has created many unique images of wildlife with its incomparable creativity. Beavers are like lively elves, moving freely on the water; Moose are like giants on land, roaming the jungle; Polar bears are kingly patrolling their territory leisurely; The bison herd shows a primitive power, galloping across the grassland; Orcas writh and jump in the ocean, showing the agility of marine life; The reindeer seem to be the messengers of autumn, carrying a mysterious atmosphere; Grizzly bears, on the other hand, show their strength and courage and are fearless wherever they are. Canada's coastline is known for its stunning scenery and rich ecology. Lakes and rivers crisscross like emerald veins, containing 20% of the world's fresh water**. Nourished by rivers, Canada's interior is just as vibrant. The majestic Rocky Mountains rise into the sky, as if they are the backbone of the earth; The vast boreal forest is like an endless picture, showing the diversity of life; The tundra and the rolling flat are like the ** of the earth, delicate and warm; The Canadian Shield is nature's secret treasure trove, where scientists have discovered the world's oldest geological formations. Overall, Canada is a country full of charm and energy. With her natural beauty and rich biodiversity, she showed the world a sample of the earth's ecosystem full of life. 
The United States, a vast continent that is not connected by one continent, is endlessly diverse. Of the 50 states in North America, only 48 are closely interdependent, bordering Canada and Mexico to the south. Alaska, on the other hand, is a lonely pearl that occupies one-fifth of the United States' land area, and it does not join hands with other states, but extends into the western part of Canada. And Hawaii, a state far from the mainland, is like a bright star in the Pacific Ocean, separated by 2,000 miles (3,200 kilometers) from the continental United States. Because of the size of the United States, not all of the states are connected, making the United States the country with the most diverse climate types in the world. The tropical climates of Hawaii and Florida, the dry deserts of the southwestern states, the polar climates of Alaska, and the Arctic climate of the western Rocky Mountains are just a few examples. However, most of the 48 neighboring states are classified either as temperate states (abundant rain, hot summers, and mild winters) or continental (mild summers, cold winters). 
China is on a par in size with the United States and Canada, so much so that some geographers dispute how China compares to the two North American giants. However, China's coastline is much smaller than that of the other three largest countries. However, China is technically the fourth largest country in the world because countries have as their territories some continental shelves that extend into the oceans. But if you measure the area above the water in each country, China would actually become the second-largest country, followed by the United States and Canada. China shares borders with 14 countries and spans five geographic time zones, but the whole country follows only one standard time, Beijing time. The country is blessed with a variety of terrains – forests, deserts, grasslands, high, arid plateaus, humid coastlines, and thousands of rivers, including the Yangtze River, the third largest river in the world. The world's highest mountain, Mount Everest, sits on the border between China and Nepal. In this vast territory, a variety of natural and cultural landscapes complement each other, which is amazing. 
Brazil, located in South America, has a vast territory, like a huge emerald, lying across the waist of the earth. Its territory is like a huge wedge, facing the 10 countries of the African continent across the sea. The Amazon River, a dragon that flows like a stream of life, originates in Brazil and is the world's largest flowing river, nourishing thousands of miles of land.
Although Brazil is world-famous for the Amazon River and its rainforests, there is much more to it than that. Look at the 7,400 kilometers of Atlantic coastline, like a glittering necklace, set around Brazil's neck, showing her grace. Pine forests, wetlands, plateaus and the arid grasslands of the Pampas – these natural elements weave together in a spectacular picture of the Brazilian landscape.
Brazil, a country of diverse cultures and natural beauty, whispers her story to the world in every inch of her land. Here, you can feel the majesty of nature, and you can also appreciate the prosperity and colorfulness of human civilization. This is Brazil, a country full of charm and vitality waiting to be explored and discovered.
Australia, a continent-wide country, is the world's sixth-largest country. She has 34,000 kilometers of fertile coastline and 21,126 miles of rainforest, but surprisingly, more than a third of this vast expanse is covered by desert. The land is home to some of the world's most dangerous animals, such as the box jellyfish (Chironex Fleckeri), the saltwater crocodile (Crocodylus porosus) and the eastern brown snake (Pseudonaja textilis). These dangerous animals are daunting, but at the same time they make Australia's biodiversity richer.
India, this land of mystery and abundance, is like a brilliant jewel embedded in the southern tip of the Asian continent. It attracts the attention of all over the world with its unique charm, irresistible charm. Even though it's not the largest country, it's amazing enough in size. Its vast territory, second only to another giant in Asia, is unmatched by its rich diversity and uniqueness. India is a huge peninsula, surrounded by the sea on three sides, and is affectionately embraced by the vast Indian Ocean. This makes the Indian Ocean a natural barrier and a source of life for it. India is like a brilliant jewel set in the bosom of this ocean, shining brightly. Although India is not as vast as some countries, it has a large enough population to stand out from the crowd. The giant of this South Asian subcontinent, apart from China, is the most populous country in the world. It is expected that in the near future, that is, in 2023, it will surpass China in terms of population and become the world's first. India's topography is a magnificent picture, consisting of towering Himalayas and fertile Gangetic plains. Its northern floodplain is one of the richest in India. Its northeastern part, covered in dense rainforest, is full of mystery and life. India is also a gift from nature. The influence of the monsoon has led to humid air in India during the summer months, bringing abundant rain to the land. And in winter, cool, dry air blows in from the ** plateau, creating a dry season that is characteristic of India. This peculiar climatic phenomenon makes the Indian landscape even more unique and fascinating. This is India, a country full of charm and wonder. Its vast territory, rich and diverse cultural landscapes, unique climatic phenomena, and the warmth and energy of its people have all made India the focus of the world's attention. Although its size is not the largest, its uniqueness and richness are enough to make it unique on the world stage.
