Which consequence results when extensive hydraulic mining unearths large loess deposits?

💡 Explanation

When mining exposes loess, previously stabilized fine silt and clay particles become vulnerable to wind erosion via deflation. This process removes the surface sediments, creating widespread dust storms, because there's no vegetation present to anchor the newly exposed material; therefore, Dust Bowl-like severe wind erosion, rather than altered fluvial drainage, follows.

• Which mechanism amplifies coastal erosion rates along the eastern Pacific coastline during a strong El Niño event?
• Which risk increases when coastal afforestation near mobile dunes is conducted without permeability planning?
• Which risk increases when an artificial levee is constructed on an active alluvial fan?
• Which mechanism contributes to tsunami formation along subduction zone fault lines during earthquakes?
• Near large desert regions, which outcome results from subsidence within the Hadley cell?
• Which atmospheric motion results because the Coriolis effect deflects air masses moving poleward in Hadley cells?
