chapter 6 Flashcards
Where does/did Earth’s water come from?
Asteriods
Some water in mantle
gysers
What ocean is the biggest? And how much does it make up
Pacific 50%
Surface Water is made up of how much freshwater?
77.78%
Where does most of the surface water come from?
Ice sheets and glaciers
What are the three stages of water?
Solid
Liquid
Gas
When water is a solid is more or less dense?
less dense
Solid to Gas?
Sublimation
Gas to Solid
Depositon
Gas to liquid
Condesation
Liquid to Gas
Evaporation
Solid to liquid
melting
Liqud to Solid
Freezing
Solid, Liquid, Gas. In that order are the calories absorbed or relased?
absorbed and are increased
80+, 100+. 540+
Gas, Liquid, Solid. In that order, are the calories absorded or relased?
relased, and decreased
-540, -100, -80
What is the formula of absolute humidity?
Mass/volume
Define Humidity?
water content of air
What are the measures of humidity?
absolute, relative, specific, dewpoint
What happens to water vapor if the volume changes?
It stays the same, only the humidity will change as well
What is the formula of relative humidity?
(actual water vapor/water vapor capacity at T ) * 100
what does the mac water capacity depends on?
temp
High relative humidity, temp=?
Low Temp
Low Relative Humidity, temp=?
High Temp
What is the formula for specific humidity?
mass watervapor/ total mass o air
*** not affected by changes in Temp, Vol, P
When saturation occur?
R.H =100%
rate of evaporation = condesation
Dewpoint Temp,—?
Temp at which air is saturated
Define Stability?
the tendency of the atmosphere to ressit upward motion and instead stay in place ( or sink)
Parcel is Stable==?
resisit upward movement
or sinks back to start point
