← GeographyWhat results where prevailing winds encounter topography blocking particle saltation?
A)Loess deposit downwind accumulation✓
B)Barchan dune crescent stabilization
C)Desert pavement surface expansion
D)Ventifact abrasion rate increase
💡 Explanation
Loess deposits occur due to obstruction affecting airflow which then dramatically decreases, arresting particle motion via deposition. This is aeolian suspension because the wind shadows limit surface saltation, therefore creating a location for accumulation, rather than further erosion processes.
