Which dune formation outcome occurs given inconsistent wind directions?

💡 Explanation

Star dunes form because multidirectional winds lead to opposing sand transport, generating dunes with multiple arms; this is aeolian transport rather than simpler transverse ridge or barchan migrations which require dominant wind directions.

• Which phenomenon increases rain acidity under specific conditions?
• On a sloping terrain underlain by permafrost, which landform results primarily due to extensive solifluction?
• Which jet stream migration occurs due to the Ferrel cell transport of temperate air masses poleward?
• Which mechanism primarily maintains gyre circulation in subtropical ocean basins?
• Which global weather pattern is significantly influenced by the Coriolis effect deflection acting on zonal wind circulation?
• Which hydrologic outcome results when atmospheric streams encounter orographic barriers?
