An anemometer is used to measure ______.

• Temperature

• Humidity

• Wind speed

• Dew point

Answer explanation

An anemometer is specifically designed to measure wind speed, making it essential for meteorological studies and weather forecasting. The other options, such as temperature and humidity, are measured by different instruments.

How does a hygrometer work?

• It uses a dry and wet bulb thermometer

• It measures the speed of spinning cups

• It uses materials that change shape based on humidity

• It contains liquid that expands and contracts

Answer explanation

A hygrometer works by using materials that change shape or electrical properties in response to humidity. This allows it to measure moisture levels accurately, making this choice the correct answer.

A barometer measures ______.

• Rainfall

• Air pressure

• Temperature

• Humidity

Answer explanation

A barometer is an instrument specifically designed to measure air pressure. It helps in weather forecasting and understanding atmospheric conditions, making 'Air pressure' the correct answer.

Which instrument is this?

• Rain Gauge

• Weather Balloon

• Thermometer

Answer explanation

A thermometer is an instrument used to measure temperature. It is distinct from a rain gauge, weather balloon, and hygrometer, which measure precipitation, altitude, and humidity, respectively.

What does an Anemometer measure?

• It measures wind.

• It measures the rain.

• It tells you when it will storm.

Answer explanation

An anemometer is a device specifically designed to measure wind speed and direction. It does not measure rain or predict storms, making 'It measures wind' the correct choice.
