How does increasing wind speed affect the appearance of a windsock?

• A. It becomes shorter
• B. It becomes vertical
• C. It stretches horizontally
• D. It changes color

Answer: (C)

Increasing wind speed makes a windsock sit more stretched out in the wind. A windsock is a flexible fabric tube that inflates when air pushes through it. As wind strengthens, more air fills and pushes the sock outward, so it tilts away from the pole and appears stretched horizontally, roughly downwind. In light wind it may hang more vertically, but with stronger wind it becomes more horizontal. The length stays about the same, and it doesn’t change color, so the only noticeable change with wind speed is the horizontal stretch.
