GEOG 1900 EXAM 2 – Questions And Complete AnswersWhat is the hydrologic cycle? Correct Ans - A continuous exchange of
water among atmosphere, the earth, and water bodies
What is humidity? Correct Ans - The amount of water vapor in the air
How is air's capacity for water vapor related to temperature? Correct Ans
- The higher the temperature, the more water vapor a volume of air is
capable of holding.
air is saturated when Correct Ans - mixing ratio = saturation mixing
ratio, the dew point = air temperature, the relative humidity is 100%
How can air become saturated? Correct Ans - When evaporation adds
water vapor to the air, cool air to dew point, mixing of warm and cool air
Humidity Indices Correct Ans - Mixing ratio, dew point, relative
humidity
What is the mixing ratio? Correct Ans - the mass of water vapor in a unit
of air compared to the remaining mass of dry air
What units are used for mixing ratio? Correct Ans - G/kg
What makes a mixing ratio change? Correct Ans - Temperature and
atmospheric pressure
Does mixing ratio vary throughout the day? Correct Ans - Yes
What is saturation mixing ratio? Correct Ans - The mixing ratio that
would exist if the air were saturated
What is an air parcel Correct Ans - Imaginary volume of air enclosed in a
thin balloon-like bubble.
What is saturation mixing ratio dependent on? Correct Ans -
Temperature and atmospheric pressure
, What is relative humidity? Correct Ans - the amount of water vapor
present in air expressed as a percentage of the amount needed for saturation
at the same temperature.
What are the two ways to change temperature of air? Correct Ans -
Diabatic processs and adiabatic process
What is a diabatic process? Correct Ans - A process in which energy is
added or removed from a system
What is an example of diabatic temperature change? Correct Ans -
Heating your stove, using the fridge
What is adiabatic? Correct Ans - When the temperature is changed
without the addition or removal of heat
Relative humidity is dependent on what 2 things? Correct Ans - Actual
quantity of water vapor and temperature
What is dew point? Correct Ans - The temperature at which
condensation begins
What does dew point temperature indicate? Correct Ans - Actual
moisture content
What is dew? Correct Ans - tiny drops of water that form on cool
surfaces at night, when atmospheric vapor condenses.
When is dew most likely to occur? Correct Ans - Early morning
What is frost? Correct Ans - Ice crystals (deposition)
What is deposition? Correct Ans - gas to solid
What is frost point temperature? Correct Ans - Occurs when dew point
temperature is below 0 degrees Celsius (i.e., change of name from "dew" to
"frost").
