Weather Measurement Instruments and Their Importance

The video tutorial covers various weather instruments, including rain gauges, thermometers, wind vanes, anemometers, barometers, and hydrometers. Each instrument's function is explained, such as measuring rainfall, temperature, wind direction and speed, air pressure, and humidity. The tutorial emphasizes the importance of understanding these measurements for practical applications like farming and daily weather forecasting.

What is the primary purpose of a rain gauge?

• To measure the amount of rain that has fallen

• To predict future rainfall

• To measure air pressure

• To determine the wind direction

How can a rain gauge be useful for farmers?

• It shows the wind speed

• It indicates how much rain the crops have received

• It measures the temperature of the soil

• It helps in predicting the next rainfall

Which of the following is NOT a type of thermometer?

• Wind vane thermometer

• Infrared thermometer

• Mercury thermometer

• Digital thermometer

What does a thermometer measure?

• Temperature

• Rainfall

• Wind speed

• Humidity

What does a wind vane indicate?

• The amount of rainfall

• The speed of the wind

• The temperature of the air

• The direction from which the wind is coming

Why is it important to know the wind speed?

• To predict the next storm

• To determine the air pressure

• To decide on appropriate clothing and outdoor activities

• To measure the humidity

What does a barometer measure?

• Wind speed

• Humidity

• Air pressure

• Rainfall

How does air pressure affect the weather?

• It determines the amount of rainfall

• It measures the humidity

• It predicts the next storm

• It influences temperature and wind speed

What does a hydrometer measure?

• Humidity

• Wind direction

• Temperature

• Air pressure

Why is it important to know the humidity level?

• To predict the wind speed

• To determine the air pressure

• To understand the moisture content in the air

• To measure the temperature
