Hands On Weather II: More Weather Experiments

The video tutorial explores various weather phenomena and experiments. It covers air pressure differences at different altitudes, measuring humidity with a sling psychrometer, and how the atmosphere traps heat. Experiments demonstrate temperature differences between land and water, the effect of sun angle on temperature, and air circulation. The tutorial also explains light refraction and rainbows, concluding with a quiz to review key concepts.

What happens to air pressure as you ascend to higher altitudes?

• It increases.

• It decreases.

• It remains the same.

• It fluctuates randomly.

What instrument is used to measure relative humidity and dew point?

• Barometer

• Anemometer

• Sling Psychrometer

• Thermometer

Why does the wet bulb temperature fall during the sling psychrometer experiment?

• Because the air gets warmer.

• Because water evaporates, cooling the air.

• Because the air pressure increases.

• Because the thermometer is faulty.

What role does the atmosphere play in regulating Earth's temperature?

• It blocks all sunlight.

• It has no effect on temperature.

• It traps heat, keeping the planet warm.

• It increases temperature fluctuations.

Which material heats up and cools down the slowest?

• Soil

• Metal

• Sand

• Water

What is a wind vane used for?

• Calculating humidity

• Measuring wind speed

• Measuring air pressure

• Determining wind direction

How is wind named?

• By the direction it is going

• By the direction it comes from

• By its speed

• By its temperature

What phenomenon occurs when light bends as it passes through different mediums?

• Absorption

• Reflection

• Refraction

• Diffusion

What is required to create a rainbow using a pan of water?

• A thermometer

• A piece of black paper

• A small square mirror

• A flashlight

What is the main cause of a rainbow's formation in the sky?

• Absorption of light

• Refraction and reflection of light in water droplets

• Reflection of light

• Diffusion of light
