What is the term for a broad, flat plain composed of wind-blown silt particles that have accumulated over thousands of years, often originating from glacial outwash plains?

💡 Solution & Explanation

Loess is an aeolian sediment composed primarily of wind-blown silt particles that accumulate over vast areas, often originating from glacial outwash plains and forming highly fertile agricultural soils. Unlike desert ergs characterized by shifting sand dunes, loess deposits are cohesive and form steep vertical bluffs.
