humidity trivia questions
Humidity describes the amount of what in the air?
Answer: Water vapor
Bonus fact: Humidity measures atmospheric moisture.
What does 100% relative humidity mean?
Answer: Air is saturated at that temperature
Bonus fact: At 100% relative humidity, the air holds as much vapor as it can at that temperature.
Why does high humidity make sweating less effective?
Answer: Evaporation slows
Bonus fact: Moist air reduces the rate at which sweat evaporates.
High humidity makes heat waves more dangerous because it slows what cooling process?
Answer: Sweat evaporation
Bonus fact: Evaporation is a major way the body loses heat.
The dew point is the temperature to which air must be cooled for relative humidity to reach what value?
Answer: 100%
Bonus fact: A higher dew point indicates a greater amount of moisture in the air.
On an insect, antennae are used mainly for what purpose?
Answer: Sensing the environment
Bonus fact: Insect antennae can detect odors, touch, humidity, vibration, and other environmental cues.
Why does air become drier after crossing a mountain?
Answer: It descends and warms
Bonus fact: Descending air warms and its relative humidity falls.
Why are seeds often kept cold and dry in a seed bank?
Answer: To slow aging and germination
Bonus fact: Low temperature and humidity can greatly extend seed viability.
What mainly determines a snowflake's shape as it falls?
Answer: Temperature and humidity
Bonus fact: Changing atmospheric conditions control crystal growth.
Air conditioning primarily changes indoor temperature and what?
Answer: Humidity
Bonus fact: Air conditioners cool and dehumidify indoor air.
An air mass is a large body of air with similar temperature and what?
Answer: Humidity
Bonus fact: Air masses acquire characteristics from their source regions.
If air temperature and dew point are nearly equal, what is likely high?
Answer: Relative humidity
Bonus fact: Small temperature-dew point spreads indicate near-saturation.
