Final answer:
The Yellow River, known as "China's Sorrow" for its floods, drains the North China Plain and carries significant silt, earning its name.
Step-by-step explanation:
The river that drains the North China Plain and is sometimes referred to as "China's Sorrow" due to its devastating floods is the Yellow River. This river is also called the "Yellow" River because of the light-colored silt it carries from the Tibetan highlands through the plain into the Yellow Sea. The fertile loess soil it disperses along its banks is highly conducive to agriculture, allowing for the cultivation of wheat, sorghum, corn, soybeans, and other smaller plot crops. However, the loess is easily moved, which has historically led to regular flooding, creating cycles of rich harvests and catastrophic natural disasters.
