Answers |Actual Complete Exam |Already Graded A+
Geostationary Satellites (Goes) ✔Correct Answer-Stationary with respect to a fixed point on
Earth's surface (revolves at the same rate as Earth)
-Far from earth (36,000 km) = coarse spatial resolution, but good temporal sampling.
Visible satellite ✔Correct Answer-appears black where the sun is not hitting earth. See lots of
black
Infrared satellite ✔Correct Answer-shows a picture of the whole earth- also shows white
around the whole earth. reads the surrounding temp of earth, so the universe is cold, shoing
white.
Polar orbiting Satellites ✔Correct Answer-orbit the earth from pole to pole
-Closer to earth= better spatial resolution, poorer temporal sampling
Surface- Station Model ✔Correct Answer-are a simplified visual to illustrate the temp., wind
direction, wind speed, pressure, pressure tendency, cloud over, dew point, current weather of a
specific place.
*Study and know the symbols
90% of Earth's atmopshere (by mass) is below 16km (10 miles) ✔Correct Answer-...
Weather ✔Correct Answer-specific state of the atmopshere at given time/ place
Climate ✔Correct Answer-accumulation or average of weather conditions over a long period
of time
What is the atmosphere? ✔Correct Answer--a fluid
-a think layer surrounding the Earth
-Mainly a mixture of invisible gas with some solid liquid particles, that stays in place due to the
force of gravity
the major permanent gasses are ✔Correct Answer-Nitrogen -78%- source: bacterial
denitriification during decay of biological material/ Sink: N-Fixation by lightning, fires or bacteria
Oxygen- 20%- Source= photosynthesis, Photolysis/ Sink= Oxidation, decomposition, respiration
,Argon-.93%
Water in the Atm. ✔Correct Answer-Greenhouse gas
Variable concentration
Invisible
Aerosols ✔Correct Answer-particles suspended in air (dust, soot, salt)
-provide "nucleus" for cloud condensation nuclei or CCN)
-Can shade surface
How old is the universe? ✔Correct Answer-10-20 Billion (13)
How do we know?
Expansion and the hubble constant
Earth's first Atm ✔Correct Answer-lots of hydrogen
Earths 2nd ATM ✔Correct Answer-Volcanism and bobmardment
lots of CO2
Earth's third Atm ✔Correct Answer-Life
cyanobacteria
phosynthesis
Vertical Sounding ✔Correct Answer-Measurement of how temps change with height in the
atm
-weather balloons lift radiosondes into the air
actual temp is on the far right
dew point temp is on the far left
Lapse Rate ✔Correct Answer-rate at which temp decrease with height
Temp inversion ✔Correct Answer-vertical layer of the atm where temp increases with height
The Trophosphere ✔Correct Answer-the layer of the Atm from the surface of earth to 10
miles above. Temp generally decreases with altitude. This is because the atm is nearly
transparent to the suns energy and is instead heater from below by earth surface.
,Stratosphere ✔Correct Answer-layer above the trophosphere. the temp. increases with height
here. this is because it is heated from above by the ozone layer!
Mesosphere ✔Correct Answer-the third layer of the atm. generally temp decreases with
altitude. this is because the air is heated from below by the ozone layer.
Thermo sphere ✔Correct Answer-temperature is again heated with altitude by the atm.
Heat ✔Correct Answer-is the total kinetic energy of a sample of a substance.
specific heat ✔Correct Answer-amount of energy required to increase the temp of 1 gram of
that substance 1 degree celcius.
conduction ✔Correct Answer-is the process of heat transfer from molecule to molecule;
requires contact. en example is when you touch something to feel if it is warm or cold. heat is
transfered from the warmer object to the colder one.
convection ✔Correct Answer-the process of transferring energy vertically. a heated parcel
rises and the cooler air sinks to replace the warmer air.
temp advection ✔Correct Answer-is the horizontal transport of energy in the atmosphere.
Latent heatingL changing phase of water. ✔Correct Answer-is the heat absorbed or released
per unit mass when water changes phase.
energy released to form ice is called the latent heat of fusion
energy increases to allow the vaporization of water is called the latent heat of vaporization.
energy released to form condensation is called the latent heat of condensation.
water vapor can change directly to ice in a process known as deposition.
ice may also enter the gas form without melting, this is called sublimation.
radiative heat transfer ✔Correct Answer-wavelength- is the distance between wave crests
amplitude is half the height from the peak of the crest to the lowest point in the wave.
shortwave radiation- UV, visible and near infrared radiation
longwave radiation- emitted by the earth, is less energeticand is characterized by much longer
wavelengths, between 4 millibars and 100 millibars.
, the earth is farthest from the sun on? ✔Correct Answer-July 4th. (aphelion)
the earth is closest to the sun on ? ✔Correct Answer-january 4th, (perihelion)
if the sun is closer to the earth in january, why isnt it hot?? ✔Correct Answer-it is related to
the tilt of the earth, not its distance.
solstices ✔Correct Answer-at noon, the sun's rays strike the equator at the angle of 23 27.
occurs on june 21st and dec. 21st
Equinox ✔Correct Answer-occur when the sun's rays strike the equator at noon at an angle of
90 degrees. occur on March 20th and Sept. 22-23.
Zenith angle ✔Correct Answer-is the angel at which the sun's energy strikes a particular
location on the Earth. The angle is 0 degrees is the sun is directly over head and is 90 degrees on
the horizon.
Atmospheric gases weakly emit and absorb energy in the 10-12 micrometer region. this is
referred to as the infrared atmospheric window. ✔Correct Answer-...
Density = ✔Correct Answer-mass/ volume
Pressure= ✔Correct Answer-Force/Area
What keeps air from falling to the ground? ✔Correct Answer-Pressure change with height
opposes weight of air
Energy ✔Correct Answer-the ability to do work
potential wnergy ✔Correct Answer-potential to do work
kinetic energy ✔Correct Answer-energy of motion
internal energy ✔Correct Answer-energy of molecular motion in a substance
-total energy produced by random motions of molecules and atoms
"energy of random jiggling
conservation of energy ✔Correct Answer-energy cannot be created or destroyed, it can only
change forms
temperature ✔Correct Answer-measures the average kinetic energy of a molecule in a
substance
