Name three instruments used to measure elements of weather and briefly describe what each measures.

Here are three instruments used to measure elements of weather: 1. A thermometer is used to measure temperature. It typically contains a liquid (like mercury or alcohol) that expands and contracts with changes in heat, indicating the temperature on a calibrated scale. 2. A barometer is an instrument that measures atmospheric pressure. Changes in atmospheric pressure can indicate changes in weather, such as approaching storms or fair weather. 3. An anemometer is used to measure wind speed. It commonly consists of several cups mounted on horizontal arms that rotate in the wind, with the rotation speed indicating the wind's velocity.
