• Barometer

• Weathervane

• Hygrometer

If a wind vane's arrow is pointing toward the East, what direction is the wind coming from?

• North

• East

• West

• South

What is the key piece of information a wind vane provides?

• Wind speed (velocity)

• Wind temperature

• Wind direction

• Air density

What part of the wind vane is responsible for catching the most air and initiating the turn?

• The directional markers (N, E, S, W)

• The pivot point

• The pointer (arrowhead)

• The tail or fin

The wind vane's design is based on the idea of Unequal Surface Area. Which component has the largest surface area?

• The pivot rod

• The arrowhead

• The directional markers

• The tail or fin

Which principle causes the wind vane to stop spinning and align itself correctly?

• Principle of Equal Pressure

• Path of Most Resistance

• Path of Least Resistance

• Principle of Aerodynamics

Why is it important that the tail of the wind vane has a much larger surface area than the pointer?

• To increase the aesthetic appeal of the vane.

• To ensure the vane stays dry in the rain.

• To create a pivot balance point.

• To ensure the wind applies an unequal force, causing rotation.

The directional markers (N, E, S, W) on a wind vane are:

• Attached to the pointer and spin with it.

• Located far away from the vane.

• Used to measure wind speed.

• Fixed to the base to provide a compass reference.

What is the primary function of the pivot point (the spindle) on a wind vane?

• To store wind energy.

• To lock the vane in a single direction.

• To allow the vane to rotate freely with minimal friction.

• To display the cardinal directions (N, E, S, W).

If a wind vane points to the Northwest, the wind is categorized as a:

• Southeast wind.

• Northwest wind.

• Southwest wind.

• Northeast wind.
