What are the main isthmuses in the world? Which countries in the world have fjords

The isthmus is a narrow strip of land between two bodies of water, an intermediate bridge between continents and continents, continents and peninsulas, and a boundary between the sea. The geographical location is particularly important, most of them are the throat arteries of transportation, and some connect the two continents, such as the Isthmus of Panama, also known as the Isthmus of Central America, connecting North and South America, and the Isthmus of Suez connecting Asia and Africa; Some connect semi-peninsulas with the mainland, such as the Kra Isthmus, which is a bridge connecting the Indochina Peninsula to the north and the Malay Peninsula to the south to the Malay Peninsula and the Eurasian continent. The Perekop Isthmus connects mainland Ukraine with the Crimean peninsula.

The causes of the isthmus are complex, ranging from the drift of continental plates to the sinking of parts of the land into the sea. On Earth, the isthmus is rarely distributed, and digging a canal at the isthmus to communicate the ocean or sea can save sea voyages. The first three mentioned above are the three major isthmuses of the world, as they each involve two oceans:

For example, the Panama Canal, which connects the Atlantic and Pacific Oceans; The Suez Canal crosses the Isthmus of Suez and connects the Indian Ocean to the south and the Atlantic Ocean through the Mediterranean and Red Seas. The Kra Isthmus is proposing a canal that will allow ships to enter the Gulf of Thailand in the Pacific Ocean directly from the Andaman Sea in the Indian Ocean without passing through the Strait of Malacca.

From above you will not have a hard time finding the location of the isthmus, because we are all familiar with these places.

Mexico's Tevantepec Isthmus connects the Gulf of Mexico with the Pacific Ocean, with a width of 308 kilometers and a minimum of 220 kilometers, with a railway running through the north and south of the isthmus, and the Isthmus of Suez, which connects the Mediterranean Sea and the Red Sea in Egypt, with a width of 135 kilometers, and the famous Suez Canal; Panama's Isthmus, which connects the Caribbean Sea to the Pacific Ocean, is 75 kilometers wide and is crossed by the Panama Canal; Thailand's Kra Isthmus, which connects the Gulf of Thailand and the Andaman Sea, is 42 kilometers wide and is a land shortcut between the Pacific Ocean and the Indian Ocean. The Isthmus of Corinth, which connects the Gulf of Corinth to the Aegean Sea in Greece, is 63 kilometers wide and is also crossed by the Corinth Canal.

The Corinthian Isthmus, the Central American Isthmus, the Kra Isthmus.

Good question.

I would like to know too.

The main characteristics of the fjord: the shore walls on both sides of the sea are straight and steep, the valley floor is wide and deep.

Causes: Glacial erosion.

Distribution: There are 80 fjords in Europe, and most of the fjords in Europe are in Northern Europe, the west coast of Northern Europe: Norway, Iceland, Greenland, the west coast of North America, Ahuplasa in the United States, British Columbia, New Zealand, the southern tip of the South Island, and the south coast of Chile.

The most typical ones are found in Scandinavia, the fjords of Norway - the county of Khodaland in Norway.

Bab el-Mandeb Strait (connecting the Red Sea and the Indian Ocean, the boundary between Asia and Africa).

Turkish Straits (connecting the Black Sea and the Mediterranean, the boundaries of Europe and Asia).

The Strait of Gibraltar (the line between the Atlantic and the Mediterranean, Africa and Europe) is located between the southernmost part of Spain and the northwestern part of Africa (5°36 W35°57N).

Bering Strait (the line that connects the Pacific Ocean and the Arctic Ocean, Asia and North America).

Taiwan Strait is a strait located between Taiwan Province of China and Fujian Province, connecting the East China Sea and the South China Sea.

The Strait of Hormuz is located in southwestern Asia, between Iran and the Arabian Peninsula (56°30 E, 26°30 N).

The straits that serve as the dividing line between the two continents are:

Turkish Strait: the dividing line between Asia and Europe.

Strait of Gibraltar: the dividing line between Europe and Africa.

Bering Strait: The dividing line between Asia and North America.

Drake Passage: The dividing line between South America and Antarctica.

Danish Strait: The boundary between Europe and North America.

Mountains: Alps, located in the middle of Europe. The huge Cordillera mountain system, in a north-south direction, from North America all the way to South America! There are two mountain ranges, the Rocky Mountains in North America and the Andes Mountains in South America

Straits : The Straits of Malacca, the Straits of Gibraltar, the Bering Strait, the Panama Canal are all important straits for traffic!

Mexico's Tevantepec Isthmus connects the Gulf of Mexico with the Pacific Ocean, with a width of 308 kilometers and a minimum of 220 kilometers, with a railway running through the north and south of the isthmus, and the Isthmus of Suez, which connects the Mediterranean Sea and the Red Sea in Egypt, with a width of 135 kilometers, and the famous Suez Canal; Panama's Isthmus, which connects the Caribbean Sea to the Pacific Ocean, is 75 kilometers wide and is crossed by the Panama Canal; Thailand's Kra Isthmus, which connects the Gulf of Thailand and the Andaman Sea, has a width of 42 kilometers and is a shortcut to hail in the Pacific Ocean and the Indian Ocean. The Isthmus of Corinth, which connects the Gulf of Corinth to the Aegean Sea in Greece, is 63 kilometers wide and is also crossed by the Corinth Canal.

Located between Mozambique and Madagascar in southeast Africa, the Mozambique Strait is the longest strait in the world, with a total length of 1,670 kilometers, trending diagonally from northeast to southwest. The strait is wide at both ends and narrow in the middle, with an average width of 450 km, 960 km at its widest point at the northern end, and 386 km at the narrowest point in the middle. Most of the water in the gorge is more than 2,000 meters deep, and the maximum depth is more than 3,500 meters, second only to the Drake Strait and the Bass Strait.

The average annual temperature of the sea surface in the gorge is above 20 degrees Celsius, and it is hot and rainy, and there are hurricanes in the summer due to the convergence of air currents. Due to the depth of the water and the wide gorge, the giant ships can be navigated all year round. The strait is rich in lobsters, prawns and sea cucumbers, and is known in the world market for its tender and fatty meat.

The Mozambique Strait is a sea communication artery from the South Atlantic Ocean to the Indian Ocean, and a large part of the oil in the Persian Gulf is transported to Europe and North America through here, so it has a very important strategic position. Especially before the Suez Canal was opened, it was the only way for the European continent to go to the East through the Atlantic Ocean, the Cape of Good Hope, and the Indian Ocean. As early as the 10th century, the Arabs passed through the Mozambique Channel and came to the Mozambique region to establish a stronghold and carry out **.

In the 13th century, the Strait region was home to the Makalanga Empire, which was quite economically and culturally developed. At the beginning of the Ming Dynasty, Zheng He also went to the West and also went to the Mozambique Channel.

Due to its important geographical location, the Mozambique Channel has historically been coveted by colonizers. From the 16th century onwards, Portuguese, Dutch, French, and British invaded the region, and Mozambique and Madagascar became Portuguese and French colonies. In order to expand their colonial interests, Portugal and France built a large number of ports in Mozambique and Madagascar respectively, including Mahajanga and Tulayal in Madagascar on the east coast, and Maputo, Mozambique City, Beira and Quelimane in Mozambique on the west coast.

Among them, Mozambique City has a long history, as an ancient port during the period of great geographical discoveries and the discovery of new shipping routes, it once played an important role in the history of maritime transportation. From this port, the railway is connected to the rail network in the interior of Africa, which can cross the southern part of the continent and reach Angola's port on the Atlantic coast. This not only made the Strait of Mozambique the most convenient transportation route between the Indian Ocean and the Atlantic Ocean, but also made the strait area a base for colonizers' aggressive expansion into East Africa and Asia.

The people of the Straits region fought bravely and tenaciously for centuries to gain independence, with the declaration of independence of Madagascar on 26 June 1960, the establishment of the People's Republic of Mozambique on 25 June 1975, and the independence of the Comoros archipelago at the northern tip of the Straits on 6 July 1975.

Today, the economic value of the Straits of Mozambique is becoming more and more evident as the economies of the countries of the Straits region are changing and attracting tourists from all over the world with their beautiful scenery.

Norway is the country with the most fjords in the world!

It's not difficult to find Norway on the world map, just find the fjords! If you open a map of the world, which is not the smallest and look at the coastlines of the continents, you will find that there is no other place in the world where the coastline is so fragmented, except Norway, and the originators are the fjords, the glaciers, and the cutting of the waves of the North Sea. Norway is also known for its 10,000-kilometre coastline and 150,000 islands at the mouth of the fjord"The Land of Ten Thousand Islands"。

Norway is a long and narrow country, with a narrow east-west area, only 6 kilometers at its narrowest point, and a long distance of 1,752 kilometers between the north and the south. However, Norway has 10,000 kilometres of coastline, more than 10 times the distance between the north and the south, mainly because of the many fjords. The approximate reason is that millions of years ago, the glaciers melted and moved towards the ocean, creating a huge force in the process that cut the valley into a U-shape, and the fjord was formed where the sea poured in.

Numerous fjords and their tributaries permeate the interior and merge into the mountains, creating a spectacular natural spectacle. As the glacier snow melts in the mountains, the snow rushes down the cliffs to form waterfalls that add to the fjord's colours. Norway's fjords are the most famous in the world, with Sognefjorden, Hardangerfjorden, Geirangerfjorden and Lysefjorden being the most famous, known as Norway's four great fjords.

Norway is the country with the most fjords in the world and is known as the "Kingdom of Fishing".
