Question

Quizplus · Accepted Answer

Loess is a windblown sediment that is typically unconsolidated and composed of silt-sized particles. It can be easily eroded if not stabilized by moisture and vegetation. Therefore, option A is the correct choice. Loess is not most common in desert regions (option B). It is actually more commonly found in regions with grasslands and moderate to high rainfall. Option C is also incorrect because loess can be very fertile and good for crops.
