Along desert margins, which mechanism causes ventifacts to develop aligned facets, given consistent wind direction and sediment supply?

💡 Explanation

Selective particle saltation causes ventifact facets because repeated abrasion leads stronger winds to preferentially remove particles from specific rock faces oriented towards consistent wind direction; therefore facets align this way, rather than random weathering.
