The main outflow and inflow rivers and flow directions in Asia

The general direction of the outflow river is from south to north.

Asia is the continent with the largest number of major rivers in the world, with as many as 58 rivers with a length of more than 1,000 kilometers, including 7 rivers with a length of more than 4,000 kilometers.

Yangtze River, Yellow River, Lancang-Mekong, Irtysh-Ob, Heilongjiang-Amur, Lena and Yenisei Rivers.

Many rivers by region are cross-regional, and geography often uses the classification by river system.

According to the water system. The main water systems in the Pacific Ocean are the Heilongjiang-Amur River, the Yalu River, the Yellow River, the Huai River, the Yangtze River, the Pearl River, the Lancang-Mekong River, the Yuanjiang-Red River, and the Chao Phraya River.

The main water systems in the Indian Ocean are the Nu-Salween River, the Irrawaddy River, the Brahmaputra River, the Ganges River, the Shiquan River-Indus River, the Euphrates River, and the Tigris River.

The main rivers of the Arctic Ocean are the Kolyma, Indigirka, Lena, Yenisei and Irtysh-Ob rivers.

The main inland water systems are the Tarim River, the Ili River, the Amu Darya, the Syr Darya River, and the Ural River.

The most dominant river in the Atlantic water system is the Kizil River in Turkey.

Some of the above are not often heard, but they are important rivers in the region, such as the Yalu River, which is the longest river in the Korean Peninsula, the Chao Phraya River, a famous river in Southeast Asia, and the Kolyma River, which is more than 2,600 kilometers long in Eastern Siberia. Turkey's Kyzyl River is the longest river in Asia that flows into the Atlantic Ocean.

The flow of Asian rivers is characterized by their origins in the mountains of the central plateau and radiating to the surrounding oceans.

The topography of Asia is characterized by high in the middle and low in the surrounding areas, which causes the rivers to flow from the middle to the periphery, so the flow direction of the Asian rivers is characterized by the plateau and mountains originating in the central part of the country and flowing radially to the surrounding oceans. For example, the length and flow of the Yangtze River (more than 6,300 kilometers) rank first in Asia; Mekong.

The territory of our country is called the Lancang River.

flows through Asian countries the most).

The main terrain of Asia.

The central part is the Qinghai-Tibet Plateau and the Pamir Plateau with an average altitude of more than 4,000 meters.

In the southern part of the Tibetan Plateau, there are the Himalayas, the world's tallest mountain range, and the world's highest peak (8844 43 meters above sea level, Mount Everest.

The Tibetan Plateau is surrounded by low-altitude plateaus and plains.

There are the West Siberian Plain and the Mongolian Plateau in the north, the Northeast Plain and the North China Plain in the east, the Indus River Plain, the Ganges Plain and the Deccan Plateau in the south, and the Iranian Plateau on both sides.

Rivers that flow directly or indirectly into the ocean are called outflow rivers. The basin of the outflow river is called the outflow zone. Rivers that do not flow into the ocean, flow to inland lakes or disappear in the middle are called inland rivers. The basin of an endorheic river is called the endorheic zone.

Outflow rivers and their hydrological characteristics: The hydrological characteristics of the outflow rivers in the south and north are obviously different from the Qinling-Huaihe River: the outflow rivers in the south have large flows, small seasonal changes in water level, long flood seasons, small sediment content, and no freezing periods; Except for a few rivers such as the Heilongjiang River in the north, the flow of river water is small, the seasonal change of water level is short, and the sediment content is large.

The reason for this is the high amount of precipitation in the south; The rainy season is long, the vegetation is more lush, the sediment content of the river is less, and the temperature in winter is above 0. The North is the opposite.

Main inland rivers and their hydrological characteristics: China's internal rivers are mainly distributed in the northwest, and the Tarim River is the largest inland river in China. Alpine ice and snow melt is the main source of water for inland rivers, so the hydrological characteristics of rivers are closely related to the seasons.

1 All of Asia has a large land area and many large rivers. Most of Asia's rivers originate in the mountains of the central plateau and flow radially to the surrounding areas.

The major rivers flowing into the Pacific Ocean are the Heilongjiang, the Yellow River, the Yangtze River, the Pearl River, and the Mekong River.

The main rivers that flow into the Indian Ocean are: Ganges, Indus, Brahmaputra, Irrawaddy, Salween, Euphrates, Tigris, etc.

The rivers that flow into the Arctic Ocean mainly include the Ob, Yenisei, and Lena rivers.

The main inland rivers are the Amu Darya, Syr Darya, Tarim and so on.

The main outflow rivers in Asia are:

eastward: China's Yangtze River, Yellow River, Pearl River, Heilongjiang River, etc.;

southward: Mekong, Irrawaddy, Ganges, Indus, etc.;

Flowing north: Ob, Yenisei, Lena, etc.

The main inland rivers of Asia: Amu Darya, Syr Darya, Tarim, etc.

Characteristics of river flow in Asia: Most of the rivers originate in the central part of the country, resulting in radial development of rivers. The topography of Asia is high in the middle and low on all sides, and rivers flow from the middle to the periphery.

For example, the Yellow River and the Yangtze River both originate in the plateau and flow to the ocean. Asia is surrounded by plains, such as the Siberian Plain and the Indus Plain, while the central region is surrounded by higher plateaus, the Tibetan Plateau and the Pamir Plateau.

The source of rivers is either mountains or plateaus, and the water flows lower under the influence of gravity, and the topography of Asia causes most rivers to flow from the middle source to the surrounding oceans.

There are many great rivers in Asia, most of which originate in the central high mountains and flow radially in all directions. The rivers that flow into the Pacific Ocean include the Heilongjiang, the Yellow River, the Yangtze River, the Pearl River, the Mekong River, etc.; The rivers that flow into the Indian Ocean include the Indus, Ganges, Salween, Irrawaddy, Tigris, and Euphrates; The Ob River, the Yenisei River, and the Lena River flow into the Arctic Ocean. The inland rivers are mainly distributed in the arid areas of central and western Asia, including the Syr Darya, Amu Darya, Ili River, Tarim River, Jordan River, etc.

The largest waterfall in Asia is the Joog Falls on the Shrabhati River on the southwest coast of India, with a drop of 253 meters.

There are not many lakes in Asia compared to other continents, but many of them have their own characteristics and are famous all over the world. For example, the Caspian Sea, the Eurasian boundary lake, is the world's largest lake and the largest saltwater lake; Lake Baikal is the deepest lake in the world and the largest freshwater lake in Asia; The Dead Sea is the lowest depression in the world; Lake Balkhash is an inland lake with both fresh and salt water. Asian lakes are widely distributed, which can be roughly divided into North Asia, Central Asia, West Asia, the Qinghai-Tibet Plateau and the middle and lower reaches of the Yangtze River.

Most of Asia's rivers originate in the central mountains and empties into the Pacific, Indian and Arctic oceans. Among them, there are 7 rivers with a length of more than 4,000 kilometers, the longest river is the Yangtze River, followed by the Ob River with the Irtysh River as its source. The Caspian Sea is the largest lake in the world, and Lake Baikal is the largest freshwater lake in Asia, as well as the deepest and oldest lake in the world, with the deepest part of the lake bottom located 1,295 meters below sea level.

With a total length of 2,540 km, the Amu Darya River is the longest inland river in Asia. The Tigris and Euphrates, the Yellow River, and the Indus Valley are the birthplaces of the earliest human civilizations. The Ganges is a sacred river of Hinduism and Buddhism.

The Mekong River is an important international river and includes China, Myanmar, Laos, Thailand, Cambodia and Vietnam.

The flow of Asian rivers is characterized by a radial shape. Asia is the continent with the highest average altitude in the world except Antarctica, and the great rivers of Asia mostly originate from the plateau mountains in the central part of the country, and flow into the sea in all directions along the terrain in a radial shape.

Advantages of the flow direction of Asian riversAsia is surrounded by plains with relatively flat terrain, Siberian Plain and Indus River Plain, etc., while the central region is a higher plateau, Qinghai-Tibet Plateau and Pamir Plateau, etc., the source of rivers is either a mountain or a plateau, gravity under the water flows to a low place, and the Asian topography prompts most of the rivers to flow from the middle source to the surrounding ocean.

Most of the rivers in Asia originate from the central mountains and flow into the Pacific, Indian and Arctic oceans, among which the rivers with a length of more than 4,000 kilometers have seven longest rivers are the Yangtze River, followed by the Ob River with the Irtysh River as the source, the Caspian Sea is the largest lake in the world, Lake Baikal is the largest freshwater lake in Asia, and it is also the deepest and oldest lake in the world.

The flow characteristics of Asian rivers are radial along the terrain and flow into the sea in all directions.

Most of Asia's great rivers originate in the Tibetan Plateau, a mountainous plateau in the central region, with most outflow rivers flowing into the Pacific Ocean and some rivers flowing into the Indian Ocean and the Arctic Ocean.

Reason: The terrain of Asia is very undulating, with high central and low circumference; Most of Asia's great rivers originate in the plateau and mountains in the central part of the country, and flow radially along the terrain into the sea.

Natural resources of Asia

Mineral resources: There are many kinds of minerals in Asia, with large reserves, mainly petroleum, coal, iron, tin, tungsten, antimony, copper, lead, zinc, manganese, nickel, molybdenum, magnesium, chromium, gold, silver, rock salt, sulfur, precious stones, etc.

Among them, the reserves of oil, magnesium, iron, tin, etc. rank first among all continents.

Forests and grasslands: Total forest area accounts for about 13% of the world's total forest area. Timber forests 2 3 or more have been developed and utilized.

Afforestation has developed to a certain extent. The Asian part of Russia, the northeastern part of China, and the northern part of North Korea are the world's most widely distributed coniferous forest areas, with abundant stocks and many species of precious timber trees.

South China, southwest China, the southern slope of the Japanese mountains, the southern slope of the Himalayas is particularly rich in plants, in addition to the common broad-leaved tree species, there are palms, palmettos, cedars, metasequoia, etc. The tropical forests of Southeast Asia occupy an important position among the world's forests and are known for their constant and abundant plant communities. Its main tree species is dipterocarp, as well as "living fossils" such as tree ferns, ginkgo, and cycads.

Features: The topography of Asia is medium high. The surroundings are low, and the river also flows from the middle to the four sides.

For example: the Yellow River and the Yangtze River. They all originate in the plateau (the middle of Asia) and flow to the ocean (around Asia).

Reason: The overall topography of Asia is high in the west and low in the east, and there are about three directions in which rivers flow.

1.Flows eastward into the Pacific Ocean (e.g. the Yangtze River. Yellow River).

2.It flows southwards like the Indian Ocean (e.g. the Brahmaputra River).

3.Flows northward into the Arctic Ocean (such as the Yenisei and. Lena River. Ob River) of course exists as an inland river (Tarim River).
