Skin friction drag. As the layers of air move over a rough surface, the air particles in the layer closest to the surface collide with the surface. This makes the air particles slow right down (and right at the surface, they completely stop!).

WebAccording to the upper equation, the air resistance can be reduced if we reduce the air density, decrease the object speed, or decrease the cross-sectional area. But in most cases, we want to move as fast as possible, and also we can not change the air density, in reality, therefore, the only realistic option is reducing the cross-sectional area.
