How old is the Yellow River, how old is the Yangtze River, how long is the Yellow River, how long is

The main stream of the Yangtze River, Yichang, is the upper reaches, with a length of 4,504 kilometers and a basin area of 1 million square kilometers, of which the Zhimen River is called the Jinsha River from Zhimen to Yibin, which is 3,464 kilometers long; The section of the Yibin to Yichang River is commonly known as the Sichuan River, which is 1040 kilometers long; Yichang to Hukou is the middle reach, with a length of 955 kilometers and a basin area of 680,000 square kilometers.

The Yangtze River, the third largest river in the world and the largest river in China, has a main stream length of 6,397 kilometers, second only to the Nile and the Amazon, ranking third in the world.

The Yellow River, a major river in northern China, has a total length of about 5,464 kilometers and a basin area of about 752443 square kilometers. It is the fifth longest river in the world and the second longest river in China.

Yangtze River, 6,397 km.

Yellow River, 5,464 km.

The Yangtze River is the largest river in China, with a total length of 6,300 kilometers, and is the third largest river in the world after the Nile River in Africa and the Amazon River in South America.

The Yellow River is the second largest river in China, with a total length of 5,464 kilometers.

The Yellow River is 5,464 kilometers long, and the Yangtze River is 6,211.3 kilometers long.

According to various studies, the PaleoYellow River has three stages of development: the Early Pleistocene from the Tertiary to the Quaternary is the gestation period of the PaleoYellow River. In the Middle Pleistocene of the Quaternary Period (1.15 million years ago and 100,000 years ago), the ancient Yellow River was born and grew in the period.

In the Late Pleistocene (100,000 years ago, 10,000 years ago), the Yellow River formed an ocean system. [1]

The formation of the Yangtze River occurred in the Jurassic period of 100 million years ago, forming the Tanggula Mountains in the upper reaches of the Yangtze River, and the Qinghai-Tibet Plateau was slowly raised, forming many high mountains and deep valleys, depressions and rift valleys. The middle and lower reaches of the Yangtze River, the Dabie Mountains and the Wushan Mountains between Sichuan and Hubei were uplifted, the Sichuan Basin was sagging, and the ancient Mediterranean Sea retreated further to the west. 100 million years ago in the Cretaceous period.

The Sichuan Basin is slowly rising. The razing effect continued to develop, and the Yunmeng and Dongting basins continued to sink. In the Eocene 30 million to 40 million years ago, the strong Himalayan movement, the uplift of the Qinghai-Tibet Plateau, the disappearance of the ancient Mediterranean, and the general intermittent rise of the Yangtze River basin.

The degree of its rise is moderate in the east and sharp in the west. The high mountains on both sides of the Jinsha River protruded, and the Qinghai-Tibet Plateau and the Yunnan-Guizhou Plateau were significantly uplifted, and some fault basins were formed at the same time. The strong downward cutting of the river has led to the emergence of many deep and steep canyons, and the water systems that originally flowed from north to south merged with each other and flowed eastward.

The middle and lower reaches of the Yangtze River rise slightly, forming middle and low mountains and hills, and the low depression areas sink into plains (such as the Lianghu Plain, Nanxiang Plain, Duyang Plain, Suzhou-Anhui Plain, etc.). By 3 million years ago, the Himalayas were strongly uplifted, and the western part of the Yangtze River basin was further uplifted. The erosion of the ancient Yangtze River, which extends from Hubei to the four basins, accelerates and cuts through Wushan, so that the eastern and western ancient Yangtze rivers are connected together.

Judging from the above information, the age of the Yangtze River is longer than that of the Yellow River.

The Yangtze River is the largest river in China, the third largest in the world, with a total length of more than 6,300 kilometers, passing through the Qinghai-Tibet Plateau, Yunnan, Sichuan, Hubei, Hunan, Jiangxi, Anhui, Jiangsu and other provinces and regions, flowing into the East China Sea, bringing together more than 700 tributaries along the way, with a basin area of more than 1.8 million square kilometers, accounting for about 20% of China's total land area. In ancient times, it was referred to as the river, and after the Six Dynasties, it was called the Great River and the Yangtze River.

The Yellow River, second only to the Yangtze River, is the second largest river in China, with a total length of 5,464 kilometers and a total length of 5,464 kilometers, flowing through nine provinces, including Qinghai, Sichuan, Gansu, Ningxia, Suiyuan, Shaanxi, Shanxi, Henan, and Shandong. The middle reaches of the river flow through the vast Loess Plateau area, and many tributaries carry a large amount of sediment into it, making it the river with the largest sediment content in the world, and the river water is yellow, hence the name.

Yangtze River: 6,380 km.
