Which of the following terms describes a wind-blown silt deposit of fine, yellowish-gray dust that blankets large areas in parts of China, Europe, and North America?

💡 Solution & Explanation

Loess is an aeolian sediment composed of wind-borne silt that forms thick, fertile blanket deposits across regions in northern China, Central Europe, and the American Midwest. Unlike glacial till, which is unstratified debris dropped directly by melting ice, loess is sorted and transported exclusively by wind action.
