The description of the Yellow River is as follows:
1. The Yellow River passes through the mountains, goes around the plains, flies through the canyons, jumps over the hills, and roars; it irrigates the fertile fields, surrounds the factories like forests, and accepts It has more than 40 tributaries and embraces countless steep mountains. It is majestic.
2. The nine-bend Yellow River is rushing and flowing, mixed with thick silt and rolling in. From the trickle at the foot of the snow-capped mountains to the majestic coast of the Bohai Sea, it lies like a giant dragon.
3. The Yellow River rolls toward the southeast, surging with turbulent waves, setting off huge waves, and the turbid currents twist and turn, forming a series of nine twists and turns, running from the foot of the Kunlun Mountains to the edge of the Yellow Sea, splitting the Central Plains into north and south. .
Yellow River:
The Yellow River is a large river located in northern China. It is one of the longest rivers in the world and the second longest river in China (also known as the second largest river). The "yellow" in the Yellow River is actually silt. It is recorded in ancient books: "The Yellow River fights with water, and mud dwells in it." Ninety percent of the sediment in the Yellow River comes from the Loess Plateau. The soil in the Loess Plateau is loose and easily eroded and scattered. Whenever it is washed away by heavy rains, a large amount of water and soil is lost and flows into the Yellow River. The basin has long winters and short summers, a wide temperature difference between winter and summer, and distinct seasonal temperature changes.
Geological influence:
The gestation, birth, and development of the Yellow River are subject to geological processes during the geological history. The tectonic movements caused by changes in the earth's crust are the external driving force, and the hydrogeographic conditions The erosion, transportation, and accumulation caused by the lower body are internal forces. In the historical process of forming a river, it has continued to move and keep pace with the times. Soil erosion on the Loess Plateau and sediment accumulation in the lower reaches of the Yellow River have been occurring since prehistoric geological times, and have been increasingly affected by human activities since history.
According to various studies, the ancient Yellow River had three stages of development: the Early Pleistocene from the Tertiary to the Quaternary was the gestation period of the ancient Yellow River. The Middle Pleistocene of the Quaternary Period (1.15 million to 100,000 years ago) was the birth and growth period of the ancient Yellow River. During the Late Pleistocene (100,000 to 10,000 years ago), the Yellow River formed a marine water system.
Geomorphic features:
The Yellow River Basin is bounded by the Bayan Har Mountains in the west, Yinshan Mountain in the north, Qinling Mountains in the south, and empties into the Bohai Sea in the east. The terrain in the basin is higher in the west and lower in the east, and the height difference is very different, forming a three-level ladder from west to east, from high to low.
The Yogu Zonglie Basin at the northern foot of Bayan Har Mountain is the source of the Yellow River. The source area of ??the Yellow River above Maduo has a wide valley and many lakes. The Yellow River leaves Eling Lake and meanders eastward, passing between Animaqing Mountain and Bayan Har Mountain to the junction of Qingchuan and Sichuan, forming the first big river bend; the Qilian Mountains stretch across the northern edge of the plateau, forming the Qinghai-Tibet Plateau The boundary with the Inner Mongolia Plateau.
