Which environmental change is indicated when desert ventifacts disappear?

💡 Explanation

Decreased wind abrasion effectiveness occurs when vegetation cover increases, preventing the sandblasting effect; therefore, ventifacts weather down, rather than forming, because wind abrasion is weakened and can no longer sculpt rocks.
