How many islands are there in the Atlantic Ocean?

The coastlines on the east and west sides of the Atlantic Ocean are roughly parallel. The southern coastline is straight, and there are few inland seas and bays; The northern coastline is tortuous, with many coastal islands, and many bays, inland seas, and marginal seas. Islands and archipelagos are mainly found on the continental margin, and most of them are mainland islands.

There are very few islands in the open ocean. The main islands and archipelagos are Great Britain, Ireland, Iceland, Newfoundland, Cuba, Hispaniola and the Caribbean – many archipelagos in the Mediterranean, and a small part of Greenland in the Atlantic Ocean. Among the oceans, the Atlantic River basin is the most extensive, covering an area of 10,000 square kilometers.

The main rivers are the St. Lawrence, Mississippi, Orinoco, Amazonas, Paraná, Congo (Zaire), Niger, Loire, Rhine, Elbe and the Nile, which flows into the Mediterranean.

Oceania, the smallest continent in the world, has a total area of only 8.97 million square kilometers, accounting for only 6% of the world's total land area and almost half the size of Russia, the world's largest country. In our impression, there are only two countries in Oceania, Australia and New Zealand, and Australia is the only country in the world that occupies a single continent, with an area of about 7.69 million square kilometers, accounting for about the total area of Oceania.

New Zealand is located in the Pacific Ocean in the southeast of Australia, and its land area is about 10,000 square kilometers. In fact, in addition to Australia and New Zealand, there is another country in Oceania that is also quite large, that is, Papua New Guinea, located north of Australia and east of the Malay Archipelago, with a land area of about 10,000 square kilometers. The combined land area of the three countries mentioned above in Oceania is about 8.42 million square kilometers, which is about the total area of Oceania, and the remaining only about 550,000 square kilometers remain, which is obtained by adding up the area of more than 10,000 islands scattered across the vast Pacific Ocean.

Australia. The islands in Oceania mainly include three major archipelagos, namely the Micronesian Islands, Melanesian Islands and Polynesian Islands, most of which are coral islands, including about 13 countries in total, namely Palau, the Federated States of Micronesia, the Marshall Islands, Nauru, the Solomon Islands, Vanuatu, Tuvalu, Fiji, Samoa, Kiribati, Tonga, the Cook Islands and Niue. Of course, the United States also has a territory located in Oceania, that is, the Hawaiian Islands, which cover an area of about 10,000 square kilometers.

Among the above 13 island countries, the largest area is the "Solomon Islands", the Solomon Islands has more than 990 islands, with a total area of about 10,000 square kilometers, and the smallest country is "Nauru", the whole country is an independent coral island, the island area is only square kilometers, and there is another country, that is, "Tuvalu", the country is composed of 9 coral islands, and the land area is only larger than Nauru, about 26 square kilometers. Because of the low elevation of these coral islands in Oceania, countries like Nauru and Tuvalu are likely to be wiped out in the near future against the backdrop of rising sea levels due to global warming.

Oceania is located in the southwestern and southern Pacific Ocean, in the vast ocean north and south of the equator. In its narrow sense, it refers to the three major island groups of Polynesia in the east, Micronesia in the center, and Melanesia in the west.

The Pacific Ocean is the most hungry ocean on the planet, with more than 20,000 islands large and small. It covers an area of 4.4 million square kilometers, accounting for about 45 of the world's total island area.

The central and southwestern parts of the body of water with the most islands are the islands, with three major archipelagos: Micronesia, Melanesia, and Polynesia. These islands are numerous, small in size, and widely distributed.

The Aleutian Islands, the Kuril Islands, the Japanese Islands, the Ryukyu Islands and the Philippine Islands, which lie between the eastern margin of the Asian continent and the Pacific Ocean, are mostly in the shape of island arcs, extending more than 9,500 kilometers from north to south. The Malay Archipelago, which stretches more than 4,500 kilometers from east to west between the Pacific and Indian Oceans, separates the western Pacific Ocean into nearly 20 marginal seas and dozens of straits and waterways. Depending on the structure of the islands, these islands can be divided into continental, volcanic, and coral islands.

The Pacific Ocean is the largest, deepest, and most marginal ocean and island in the world. It is located between Asia, Oceania, Antarctica, and North and South America. The longest from north to south is about 15,900 kilometers, and the widest from east to west is about 19,000 kilometers, with a total area of 10,000 square kilometers, an average depth of 3,957 meters, and a maximum depth of 11,034 meters.

The name Pacific Ocean is derived from the Latin word "mare pacificum", which means "calm sea", and was named by a Portuguese navigator employed by Spain, Magellan.

Climate: Due to the vast area and uniform water bodies of the Pacific Ocean, the climate is conducive to the formation of planetary wind systems, especially in the South Pacific. The situation in the North Pacific is different, with great disparities between the east and west coasts, most notably the harsh winters on the east coast of Russia and the mild winters in British Columbia, Canada.

The trade wind belt is located between the center of the subtropical high and the equatorial windless belt between 30°-40° north and south latitudes in the eastern Pacific Ocean.

Marine resources: The Pacific Ocean is more abundant in animals and plants, whether phytoplankton or benthic plants, as well as fish and other animals. The area of shallow sea fisheries in the Pacific Ocean accounts for about 1 2 of the total area of shallow sea fisheries in the world's oceans, and marine fish catches account for more than half of the world's fish catches.

One, the Pacific Ocean.

Area: It is about 15,900 kilometers long from north to south, about 19,900 kilometers wide from east to west, and covers an area of 179.68 million square kilometers. It accounts for 35% of the total area of the world's oceans.

The Pacific Ocean is the largest, deepest, and most island-dense of the four oceans on Earth.

There are about 10,000 islands in the Pacific Ocean, with a total area of more than 4.4 million square kilometers, accounting for about 45 of the world's total island area. The mainland islands are mainly distributed in the west, such as the Japanese archipelago, Kalimantan, New Guinea, etc.; There are many scattered ocean islands (volcanic islands, coral islands) in the central part of the country. The topography of the seabed can be divided into three parts: the central deep water area, the marginal shallow water area and the continental shelf.

Abyssal basins below roughly 2,000 m account for about 87 of the total area, marginal sections between 200 and 2,000 m and continental shelves up to 200 m approximate. There is a large ocean basin in the northern half, and there are many islands in the west, and there are deep trenches on the outer side of the island arc. The northern and western marginal seas have wide continental shelves, and the deep waters in the central part are more than 5,000 metres deep.

The Hawaiian Islands and the Lane Islands divide the central deepwater zone into the Northeast Pacific Basin, the Southwest Pacific Basin, the Northwest Pacific Basin, and the Central Pacific Basin. There are a large number of volcanic cones on the ocean floor. The shallow marginal waters are mostly more than 5,000 metres deep, and the basin area is small.

II. Atlantic.

Area: It covers an area of 90,000 square kilometers, accounting for about half of the ocean area, about half the area of the Pacific Ocean, and is the second largest ocean in the world.

Important islands and archipelagos: The islands of Great Britain, Ireland, Iceland, Newfoundland, Cuba, Hispaniola and many islands in the Caribbean and Mediterranean, with a small portion of Greenland also located in the Atlantic Ocean.

Third, the Indian Ocean.

Area: 70,000 square kilometers. It accounts for about the total area of the world's oceans, and is the third largest ocean in the world.

Islands: There are many islands in the Indian Ocean, most of which are mainland islands, such as Madagascar and many small islands on the eastern edge of Africa, as well as Socotra, Sri Lanka, Andaman Islands, Nicobar Islands, Mintawe Islands, etc. There are also many volcanic islands such as Reunion, Comoros, Amsterdam, Croze, Kerguelen, etc.

In addition, the Lakshadweep Islands, Maldives Islands, and Chagos Islands in the northern part of the Central Indian Ocean Ridge, as well as the Christmas Island and Cocos Islands in southwest Java, are all coral islands.

Fourth, the Arctic Ocean.

Area: 13.1 million square kilometres, about 1,14 the size of the Pacific Ocean. It occupies about the total area of the world's oceans and is the smallest and shallowest of the four oceans on Earth.

Islands: northern Canada, Iceland, Greenland (Denmark).

The Pacific Ocean is the ocean with the largest number of islands on the earth, with more than 20,000 large and small islands and an area of 4.4 million square kilometers, accounting for about 45 of the world's total island area. The central and southwestern parts of the body of water are the most islanded, with three major archipelagos: the Micronesian archipelago (meaning small island archipelago), the Melanesian archipelago (meaning the black archipelago), and the Polynesian archipelago (meaning the multi-island archipelago), which are numerous, small in size, and widely distributed. The Aleutian Islands, the Kuril Islands, the Japanese Islands, the Ryukyu Islands, and the Philippine Islands, which are located between the eastern margin of the Asian continent and the Pacific Ocean, are mostly in the shape of islands, extending more than 9,500 kilometers from north to south.

The Malay Archipelago, which stretches more than 4,500 kilometers from east to west between the Pacific Ocean and the Indian Ocean, separates the western waters of the Pacific Ocean into nearly 20 marginal seas and dozens of straits and waterways connecting the two oceans. According to the structure of the islands, they can be divided into mainland islands, volcanic islands and coral islands (reefs): Sakhalin, Japanese archipelago, Taiwan Island, Malay Archipelago, New Guinea Island, South Island, North Island and Tasmania near the edge of the Asian continent and the Australian continent belong to the mainland islands; The Aleutian Islands, the Kuril Islands, the Ryukyu Islands, the Hawaiian Islands and other islands are mostly volcanic islands; The Caroline Islands, the Marshall Islands, the Tuamotu Islands and the Fiji Islands are mostly coral islands.

The Pacific Ocean is surrounded by Polynesia. The three major archipelagos of Micronesia and Melanesia can be divided into three categories: mainland islands, volcanic islands and coral islands.

The Pacific Islands are composed of more than 10,000 islands of different sizes, which can be divided into two categories: continental islands and ocean islands, and ocean islands can be divided into two types: volcanic islands and coral islands. Mainland islands are similar or connected with the mainland in terms of geological structure, generally located near the mainland, originally part of the continent, and later separated from the mainland due to crustal subsidence or sea level rise, such as Irian Island, New Zealand's South Island, North Island, etc. Such islands are generally larger in size and higher in terrain.

Volcanic islands are formed by the accumulation of volcanic eruptions on the ocean floor, mainly lava, such as the Hawaiian Islands in the Polynesian archipelago, which are still active today, and are characterized by high altitudes and steep terrain. Coral islands are islands formed by coral reefs outcropping out of the sea, or sand islands formed on coral reefs.

Most of the three archipelagos in the Pacific Ocean are coral islands, which are characterized by their small size, low terrain, and many ring-shaped shapes. In the middle is the lagoon, there is a gap to communicate with the ocean, the lake is calm and calm, is an excellent haven for ships. Coral reefs are formed by the accumulation of the remains of polyps.

The polyp is a coelenterate that lives in shallow tropical seas with an average water temperature of 25° 30 and high salt content and transparency, and after death the calcareous bones form limestone. At first, coral grows around the island to form a fringing reef, but as the island sinks, the coral reef continues to grow outward and upward, forming a barrier reef, and when the island continues to sink and submerge into the sea, the coral reef around the island grows upwards to form an atoll, and the top of the island is submerged by the sea to become a lagoon.

The largest archipelago in the world: the Malay Archipelago, the largest peninsula: the Arabian Peninsula, and the largest island: Greenland.

Introduction to the Malay Archipelago, the Arabian Peninsula, Greenland:

1. The Malay Archipelago, the largest archipelago in the world. The Malay Archipelago is the largest archipelago in the world. It is located in the vast sea area between the Pacific Ocean and the Indian Ocean in southeast Asia, consisting of more than 20,000 islands such as Sumatra, Kalimantan, Java and the Philippine Islands, extending 6,100 kilometers along the equator, with a maximum width of 3,500 kilometers from north to south, with a total area of about 2.43 million square kilometers, accounting for about 20 of the world's island area.

The countries on the archipelago are Indonesia, the Philippines, Brunei, Malaysia (East Malaysia), Timor-Leste and Papua New Guinea (most of the region). The island of New Guinea is sometimes excluded from the Malay Archipelago.

2. The Arabian Peninsula is the largest peninsula in the world. It is located in southwest Asia, covering an area of 3.22 million square kilometers, bounded by the northern end of the Gulf of Aqaba to the mouth of the Shatt al-Arab. Located in the strategic crossroads of Asia, Europe and Africa, it has been an important channel connecting the world and the development of human civilization since ancient times.

The Arab countries of the Arabian Peninsula have occupied an important place on the world stage, both in the past and in the present. The climate of the region is hot and dry, making it one of the hottest in the world. The desert is widely distributed, producing dates, coffee, wool, leather, etc.

Rich in oil reserves. The Arabian Peninsula is the birthplace of Islam. Muhammad, the founder of Islam, was born and lived here.

Mecca on the peninsula is the holiest site of Islam.

3. Greenland is the world's largest island, with an area of 2,166,086 km, in the northeast of North America, between the Arctic Ocean and the Atlantic Ocean. The distance from Piri in the north to Cape Favel in the south is 2,574 kilometers, and the widest point is about 1,290 kilometers, and the coastline is more than 10,000 kilometers long. The Danish territory, the capital of Nuuk, also known as Gotthob, is a typical cold climate all year round, with summer temperatures in coastal areas reaching above freezing, and inland parts freezing all year round.
