Atmospheric Wonders: Exploring Humidity, Clouds, and Winds

What instrument is commonly used to measure relative humidity?

• Barometer

• Anemometer

• Hygrometer

• Thermometer

At what temperature does the air become saturated and dew begins to form, assuming constant atmospheric pressure?

• Freezing point

• Boiling point

• Dew point

• Wet-bulb temperature

Which type of cloud is typically associated with thunderstorms?

• Cirrus

• Cumulonimbus

• Stratus

• Altostratus

What form of precipitation is characterized by balls or irregular lumps of ice?

• Rain

• Sleet

• Hail

• Snow

Which factor does NOT directly affect air pressure?

• Temperature

• Humidity

• Altitude

• Ocean currents

How does high humidity affect the feeling of temperature?

• It makes it feel cooler than it actually is.

• It has no effect on the feeling of temperature.

• It makes it feel warmer than it actually is.

• It causes temperature to decrease.

What is the relationship between air pressure and wind speed?

• Higher air pressure leads to higher wind speeds.

• Lower air pressure leads to higher wind speeds.

• Wind speed is not related to air pressure.

• Wind speed decreases as the difference in air pressure increases.

What is the term for the amount of water vapor present in the air compared to the amount needed for saturation at the same temperature?

• Absolute humidity

• Specific humidity

• Relative humidity

• Dew point humidity

Which cloud type is most likely to produce steady rain?

• Cumulus

• Cirrocumulus

• Nimbostratus

• Cumulonimbus

What causes wind to deflect to the right in the Northern Hemisphere?

• The Doppler Effect

• The Coriolis Effect

• Centrifugal force

• Gravitational pull
