If Priya is standing on a hilltop and the wind is blowing from her back towards the valley below, and she is wearing a loose, long skirt, in which direction will the skirt blow?

Respond very briefly.
Priya's skirt will blow away from her body towards the valley below. This occurs because the wind blowing from her back pushes against the fabric of the skirt, forcing it to move in the direction the wind is traveling. The loose nature of the skirt allows it to catch the wind more effectively, much like a sail, which causes it to billow outward and away from Priya's legs. The force of the wind overcomes the gravitational pull that would normally keep the skirt hanging downwards, thus the skirt will flow out and away from Priya, in the direction the wind is blowing, towards the valley.
