In the context of China's early history, the term that is especially important is Loess. Loess is a type of windblown silt that comes from the Gobi Desert and contributes to the fertile soil in regions like the Yellow River valley, which was crucial for early agricultural development in China. This soil allowed early Chinese civilizations to thrive and is significant in understanding the region's history.
Oracle bones and sand are also relevant, but loess specifically ties to the environmental conditions that affected early Chinese agriculture and settlement. Dikes, on the other hand, are structures used to control water flow and are also important in agricultural practices but are not directly linked to the aspect of wind from the Gobi Desert.
