Which depositional outcome increases when wind speed decreases across parabolic dunes?

💡 Explanation

Increased sediment deposition on the slipface occurs through gravity segregation, because decelerating winds lose energy; therefore, coarser grains deposit quicker rather than suspension of finer particles into the leeward zone or causing ridge formation.
