Earth Science Chapter 24 Test Review
2 thermometers: one is wet and one is dry. Whirl them and check the rate of evaporation by reading the temperature differences.
Describe how a psychrometer works.
Solid: least amount of kinetic energy. Particles vibrate against each other. Liquid: enough energy for particles to move freely past each other. Gas: greatest amount of kinetic energy. Particles have the most random motion.
Describe the difference in molecular motion found in ice, liquid water, and water vapor.
Alternating layers of clear and cloudy appearances.
Describe the inside appearance of a hailstone. AND why?
Equator
Evaporation is greatest near the earth's...
Water condenses on ice crystals until it's large enough to rain.
Explain how precipitation forms in supercooled clouds.
Mountain range
Forceful uplifting of an air mass can occur as the air meets a...
False, warm, cold
True or False? *Cold* air can hold more water vapor than *warm* air.
False, dew
True or False? *Dew* forms only when the dew point falls below 32°F.
False, sleet
True or False? *Hail* is formed by rain that freezes as it strikes the ground.
False, water
True or False? *Water vapor* is the most common form of water found in supercooled clouds.
False, convective
True or False? As air rises and expands, it undergoes *advective* cooling.
True
True or False? Clouds require condensation nuclei to form.
True
True or False? Condensing water vapors slows the rate of adiabatic temperature changes.
True
True or False? Glaze ice forms when rain freezes as it strikes the ground.
True
True or False? Humid air usually has a higher dew point than dry air.
False, small
True or False? Rain gauges measure the precipitation that falls over a *large* region.
True
True or False? Silver-iodide is used in cloud seeding because it resembles ice crystals.
True
True or False? Snowflakes are usually larger in 30°F air than in 11°F air.
False, gas
True or False? Sublimation is the process by which a solid changes to a *liquid.*
True
True or False? The heat energy necessary for evaporation of ocean water is absorbed from the sun.
False, status
True or False? The lowest clouds in the sky are *cirrus* clouds.
Steam
Type of fog usually formed over inland rivers and streams.
Frost
What forms when the dew point is below 0°C?
Stratus
What type of cloud forms then warm, moist air overrides a layer of cool air?
Cumulus
What type of cloud usually forms in fair weather?
Hawaii, because warmer air holds more moisture.
Where would the air contain more moisture-over Hawaii or over Canada? Why?
Stratus
Which of the cloud types occurs at the lowest altitude?
Cirrus
Which type of cloud is composed entirely of ice crystals?
Cumulus
Which type of cloud is produced by the rising and cooling of large air masses?
Advection
Which type of fog occurs as warm, moist air moves across a cold surface?
Steam
Which type of fog usually forms over inland rivers and lakes?
Sleet
Which type of precipitation forms as rain falls through a layer of freezing air?
More condensation nuclei
Why would polluted air more likely form clouds than clear air would?
1.5 cm
15cm of very wet snow falls. How much water would there be?
Specific humidity
Actual amount of moisture present in the air.
Specific humidity
Actual amount of water vapor in a volume of air.
Condense
As temperature of air falls below dew point, vapor will...
Latent heat
Heat released when water condenses and changes to a liquid.
Silver iodide (which acts as freezing nuclei) and dry ice (used to cool air) are used to induce RAIN.
How does the process of cloud seeding work?
Sublimation
Ice changes directly into water vapor by the process of...
Coalescence
In tropical regions, rain usually results from process of...
Cumulonimbus
In which type of cloud is hail usually formed?
Evaporation
Most water vapor enters the atmosphere by the process of...

One body of air has a relative humidity of 79%. Another has a relative humidity of 30%. At the same temperature, which body of air is closer to its dew point?
Drizzle
Precipitation consisting of drops smaller than 0.5mm in diameter in called...
Ground fog
Radiation fog is also called...
Gas
Sublimation -> ice changes into a...
