Which province is the loess high slope in?

The Loess Plateau does not belong to a specific province, but spans several provinces, including Shaanxi, Shanxi, Qinghai, Gansu, Ningxia Autonomous Region and Henan.

The Loess Plateau is located at the junction of northern and northwestern China. Taihang Mountain in the east, Wushaoling in the west, Qinling Mountain in the south and the Great Wall in the north. It mainly includes Shanxi, Shaanxi, Gansu, Qinghai, Ningxia, Henan and other provinces, covering an area of 400,000 square kilometers, accounting for 70% of the world's loess distribution. It is the largest loess accumulation area in the world.

1. The rocks in this area are heated and expanded during the day, cooled and contracted at night, and gradually weathered into stones, sand and clay of different sizes. In the winter and spring when the northwest wind prevails, the wind suddenly rises, flying sand and stones, and dust covers the sky. Coarse stones remain in place and become "Gobi", while finer sand grains fall in nearby areas and gather into deserts, and tiny silt and clay fly to the southeast one after another. When the wind weakened or was blocked by the winding Qinling Mountains, they stopped accumulating, and after hundreds of thousands of years of accumulation, a vast loess plateau was formed.

2. The Loess Plateau is rich in coal, oil, bauxite and other resources, and it is also an important energy and chemical base in China. Loess has fine particles, soft soil and rich mineral nutrition, which is beneficial to farming. Valley agriculture has a long history and is the cradle of ancient culture in China.
