Humidity & Greenhouse effect Flashcards
Moisture in the atmosphere is also referred to as…
humidity
water naturally occurs in the atmosphere in all ______ phases. Name the phases…
3, solid, liquid, gas
__________ is required or released as water changes state
energy
As energy is released from water phase change what happens?
temperature, cloud formation is affected in atmosphere
which state is the most ordered, least energy state?
solid
_______ is the most ordered, least energy state
solid
_________ is the higher energy and less orders then solid
liquid
which is the most energetic and least ordered (most free)?
gas
what is latent heat?
the amount of heat required or released in a phase change
the change of water into gas is the process of…
evaporation
when gas transforms into water we call that…
condensation
when water turns into a solid that is called…
freezing
when solid turns into a liquid that is called…
melting
a solid to a gas is called….
sublimation
a gas (water vapor) to a solid is called…
deposition
for each phase change there is a certain amount of energy that is either _______ or ________
absorbed, released
for each phase change there is a certain amount of ______ that is either _______ or ________
energy, absorbed, released.
when energy is absorbed the surroundings temp get _______
cooler
when energy is released the surroundings temp get _______
warmer
does evaporation absorb or release energy?
absorb, cools you down. when you sweat you evaporate and it cools you down
_____ is the amount of water vapor in the air
humidity
what is saturation?
the condition where the air cannot hold anymore water vapor
the condition where the air cannot hold anymore water vapor is called…
saturation
saturation is the condition where the air cannot hold anymore ______ _____
water vapor
what happens when you reach saturation?
either condensation or precipitation occurs
as the temp of the air _________ the max amount of water it can contain ________
increase, increases
warmer air can hold more…
moisture.
what are the two ways humidity is reported?
relative humidity and specificities humidity
what is relative humidity?
the amount of water vapor int he air compared to its saturation level
relative humidity changes with the _______ of the air and how much ______ _____ content
temperature, water vapor
what is specific humidity?
the actual mass of of water vapor int he air
what is the dew point?
temperature at which air reaches saturation
dew point is the temperature at which _____ ______ condenses into ______ ________
water vapor, liquid water
AS temp ______, dew point _________
increases , increase
AS dew point _______, Humidity __________
increase, increases
when does 100 percent relative humidity happen?
when the dew point equals the temperature
the sun releases energy in many wavelengths including…
gamma rays, X-rays, UV rays
the suns rays are ________ to anything alive
damaging
Gamma rays and x-rays are ________ by the atmosphere
absorbed
visible light is allowed to…
travel through the atmosphere, it is not absorbed much
what mostly blocks visible light?
clouds
clouds _______ scattered visible light
reflect
gamma rays, x-rays and uv rays are ________ frequency and _______ wavelength
high, short
on a fair day about 80 percent of _______ light from the sun reaches the ground
visible
once visible light reaches the ground what happens?
it can be absorbed int he the ground or reflected back up to atmpsther
the amount of reflection is called a surfaces…
albedo
if a surface is very reflective it is said to have _____ albedo
high
if a surface is not very reflective it is said to have ______ albedo
low, it absorbs heat
energy that is reflected on the surface, bounced back into the atmosphere and reabsorbed by the atmosphere causes the temp to…
rise
