Answer 2

Answer:

wind vane

Explanation:

A wind vane, also called a weather vane, is a tool for measuring wind direction and was probably one of the first weather instruments ever used. To determine wind direction, a wind vane spins and points in the direction from which the wind is coming and generally has two parts, or ends: one that is usually shaped like an arrow and turns into the wind and one end that is wider so that it catches the breeze. The arrow will point to the direction the wind is blowing from so if it is pointing to the east, it means the wind is coming from the east. Additionally, wind direction is where the wind is blowing from. Therefore a west wind is blowing from the west. To use a wind vane, you must know where north, south ,east, and west are.
