← GeographyWhich material erosion results when atmospheric pressure gradients accelerate particles?
A)Ventifact formation via abrasive winds✓
B)Oxbow lake creation from meanders
C)Caldera collapse after magma expulsion
D)Karst topography develops via dissolution
💡 Explanation
Ventifacts form because differential air pressure causes airborne particles to impact rock surfaces at high speed, resulting in *sandblasting*. Therefore wind erosion creates ventifacts on exposed surfaces, rather than fluvial (oxbow), volcanic (caldera), or chemical (karst) processes.
