Weather Quizizz 1 (Air pressure, wind, humidity)

What instrument is used to measure relative humidity?

• Baromoter

• Hygrometer

• Thermometer

• Anomometer

What instrument is used to measure atmospheric pressure?

• Baromoter

• Hygrometer

• Thermometer

• Anomometer

What instrument is used to measure wind speed?

• thermometer

• hygrometer

• anemometer

• barometer

What is atmospheric pressure?

• The force of water vapor in the atmosphere

• Force per unit area exerted by the weight of the air

• The force of wind on the earth's surface

• The force of gravity on an object

Explain how atmospheric pressure changes with altitude.

• Atmospheric pressure decreases with altitude, then increases again at higher altitudes.

• Atmospheric pressure remains constant regardless of altitude.

• As altitude increases, atmospheric pressure decreases.

• As altitude increases, atmospheric pressure increases.

What are the units used to measure air pressure?

• m/s

• mb

• °C

• kg

What causes wind to occur?

• Global warming

• Underground volcanic activity

• Movement of the moon

• Hot air rising & cold air filling its place.

Describe the relationship between air pressure and wind.

• Air pressure and wind are unrelated

• The relationship between air pressure and wind is that air pressure differences create areas of high and low pressure, which in turn cause the movement of air known as wind.

• Wind causes changes in air pressure

• Air pressure has no effect on wind

What is humidity?

• The amount of water dissolved in clouds in the sky.

• The change in pressure of the atmosphere at different temperatures.

• The amount of water vapour in the atmosphere.

• The average temperature of the atmosphere.

Explain the concept of relative humidity.

• Amount of oxygen in the air

• The weight of the air

• The speed of the wind

• Ratio of water vapor to maximum amount air can hold at a given temperature
