All continents that are divided by mountains or straits or canals

Europe and Africa – Strait of Gibraltar.

Asia and North America – Bering Strait.

North and South America – Panama Canal.

Asia and Africa – Suez Canal.

Asia and Europe – the Greater Caucasus Mountains, the Ural River, the Turkish Straits, the Ural Mountains.

The continents that are divided by canals are Asia and Africa, and North America and South America. The definition of a canal has always been different. According to the conventional formulation:

In a narrow sense, a canal is a navigable river dug by hand. Broadly speaking, a canal is an artificial waterway used to communicate water transportation between regions or waters, usually connected to natural waterways or other canals. In addition to shipping, canals can also be used for irrigation, flood distribution, drainage, water supply, etc.

China has a long history of canal construction, and the Xu River, which was dug in 506 B.C., is the world's oldest man-made canal, the earliest canal recorded in China, and the earliest canal in the world. In the 28th year of Qin Shi Huang, the Ling Canal was dug to communicate the shipping between the Xiang River and the Li River. The Beijing-Hangzhou Grand Canal, built mainly during the Sui Dynasty in China, is the longest canal in the world.

There are three types of waterways: natural rivers, canalized rivers and artificial canals, each with its own special problems. Natural rivers are often forced to suspend navigation seasonally due to drought and ice, and even lead to river diversion, forming sandbars. The waterway project should focus on strengthening the riverbed and riverbank, maintaining the original river channel, eliminating tributaries, unifying the river cross-section, cutting bends and straightening, and smoothing the water flow.

Asia and Africa.

To the southwest of Asia is Africa, and the dividing line between the two is the Suez Canal. The Suez Canal is a 190-kilometer-long canal dating back to the 12th Dynasty of Egypt, connecting the Mediterranean Sea with the Red Sea, greatly shortening the distance between the Atlantic and Indian Oceans, and making Egypt a country that straddles two continents, Asia and Africa.

Africa is separated from Europe by the Mediterranean Sea to the north, and the dividing line between Africa and Europe is in the Strait of Gibraltar, which is only 13 kilometers wide at its narrowest point.

Straight to the Strait of the Britta.

The dividing line between Asia and North America is the Bering Strait, the Bering Strait connects the Arctic Ocean and the Pacific Ocean, and the eastern Siberia region of Asia is only about 40 to 80 kilometers away from Alaska in the United States, through the Bering Strait.

The boundary between North and South America is the Panama Canal on the Isthmus of Central America, which was opened in 1914, greatly shortening the distance between North America and the Pacific Ocean, and making Panama a country that straddles North and South America.

Bounded by artificial canals, Africa and Asia, North and South America. An artificial canal is an artificial waterway used to communicate water transportation between regions or waters, and Africa and Asia are bounded by the Suez Canal; North and South America are bounded by the Panama Canal.

When the artificial canal passes through the mountains and crosses the river and river valley, the bank and riverbed inspection bench of the canal must have protection facilities to prevent erosion and leakage. The route of the Liye artificial canal was chosen to defeat the brigade and create conditions for the construction of a long-distance horizontal section of the river that could be navigated quickly.

Bounded by artificial canals, Africa and Asia, North and South America. The closed banquet canal is an artificial waterway used to communicate water transportation between regions or waters, and Africa and Asia are bounded by the Suez Canal; North and South America are bounded by the Panama Canal.

When the artificial canal passes through the mountains and crosses rivers and valleys, the banks and riverbeds of the canal must have protection facilities to prevent erosion and leakage. The artificial canal route was chosen to create conditions for the construction of a long-distance horizontal section of the river that could be navigated quickly.

1. The two continents with the canal as the dividing line are Asia and Africa, and this canal is the Suez Canal.

2. The Suez Canal is one of the most frequently used shipping routes in the world, and it is the main channel for people from Asia and Africa, and it is precisely because of the completion of the Suez Canal that the African Peninsula has become the African continent, and at the same time, it has also made Southwest Asia. ** is more frequent in places such as Northeast Africa.
