Earth Science Chapter 7 Study Guide (Water and Atmospheric Moisture) Flashcards

Terms Definitions
The Human body contains ____ water
T or F: Pure water rarely occurs in nature because it is solvent.
Water has a density of ______
Water covers approximately _____ of Earth's surface.
The process by which water and water vapor emerge from layers deep within and below the crust is called
Ice sheets and glaciers
The largest portion of fresh water today is located in:
97% of Earth's waters
Earth's oceans possess
Other than ice sheets and glaciers, the largest repository of fresh water is located in
Hydrogen Bonding
Water molecules bind tightly to one another. This is a result of:
Hydrogen end = positively charged, Oxygen end = negatively charged
Hydrogen bonding results from the fact that
Water vapor freezing to ice
The term deposition refers to
Latent Heat
What is the heat energy involved in the change of phase?
releases; heats
When water condenses, it ____ heat energy and ____ the surrounding air
Ice to water
Which of the following phase changes decreases the temperature of the air?
Water expands in volumes as it freezes
In winter, freezing water can break pipes and even crack engine blocks. How does this happen?
Water vapor in the atmosphere is called
Relative Humidity
The amount of water vapor in the air at a given temperature expressed as a percentage of the water vapor capacity of the air is called:
Temperature of both the air and the water vapor
The capacity of the air to hold water vapor is basically a function of:
Dew-point temperature
A mass of air always becomes saturated when it reaches the:
Drybulb; wetbulb
A sling psychrometer has two thermometers, one is called _________, and the other is called ________
Anemometers & barometers
Which of the following is not used to measure relative humidity?
Drier; lower
The greater the difference in temperature between the wet bulb and dry bulb on a sling psychrometers, the ___ the air is and the ____ the relative humidity
Wetter; closer
The smaller the difference in temperature between wet bulb and dry bulb on a sling psychrometer, the _____ the air is and the ______ the air temperature is to dew-point.
The general term that refers to the tendency of a parcel of air to either remain in place of change its initial position is _________
Continues to rise until it reaches an altitude at which the surrounding air has a similar temperature
An air percale is considered unstable when it
When the environmental lapse rate is greater than the dry adiabatic lapse rate the atmospheric conditions are
Conditional unstable
When the environmental lapse rate is greater than the moisture adiabatic lapse rate and less than the dry adiabatic lapse rate, the atmospheric conditions are
When the environmental lapse rate is less than the moist adiabatic lapse rate, the atmospheric conditions are:
Less; condensation heats the air
The wet adiabatic lapse rate is ____ than the dry adiabatic lapse rate because ___________
The air is simultaneously being cooled by expansion and heated by condensation
Which of the following statements regarding rising air, in which dew point temperature has been reached is correct?
Condensation nuclei and saturated air
The condensation process requires
Collision-coalescence process
The principle process for raindrop formation in tropical warm clouds is:
low; middle; high; vertically developed; cirroform; stratoform; cumul form
