Which outcome occurs when wind exceeds saltation threshold affecting coastal dunes?

💡 Explanation

Migration of the dune system occurs when the saltation threshold is exceeded, because particle entrainment increases leading to sediment transport shifting the dune; therefore migration happens, rather than stabilization outcomes under other conditions.

• Which risk increases when excessive sedimentation loads fluvial depositional fans?
• Which consequence results when increased acid rain accelerates?
• Which outcome results when insolation variability weakens the equatorial temperature gradient?
• Which outcome arises when infiltrating water encounters fractured limestone cave system?
• Which mechanism disrupts thermohaline circulation significantly when Greenland ice melt increases drastically?
