Heat is transferred in Earths atmosphere by radiation. True or False?
True
Temperature is a measure of the maximum possible speed of atoms and molecules, true or false?
FALSE ( if you said true you wrong )
Eath’s radiative equilibrium temperature is the ___________________?
Average temperature at which Earth is absorbing solar radiation and emitting infrared radiation at equal rates
In most of the world, temperature is recorded in?
Degrees Celsius
In general the temperature of a rising air parcel what
Always cools due to expansion.
Horizontal transport by the wind is called?
Advection
When water changes from a solid to a vapor, without going through a liquid state, we call this process what?
Sublimation
The transfer of heat energy by atmospheric and oceanic circulating prevents low latitudes from steadily becoming _____ and high latitudes from steadily growing _______
Warmer,
Colder
If Earths average Surface temperature were to increase, the amount of radiation emitted from the Earths surface would increase, and the wavelength of peak emissions would shift towards shorter wavelengths. T or F?
True
Carbon dioxide and water vapor are called?
Selective absorbing greenhouse gases
At which temperature would Earth be radiating energy at the greatest rate or intensity ?
105 degrees Fahrenheit
On average, what percentage of Solar energy striking the outer atmosphere eventually reaches the Earth’s surface?
50%
Carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons are the greenhouse gases that appear to be responsible for what?
The enhancement of earths atmospheric greenhouse effect
Solar wind is comprised of plasma or charged particles traveling through space? T or F?
True
Without water vapor to absorb the Earths emitted infrared radiation, what would happen?
Earth would lose more heat
If the amount of energy lost by earth to space each year were not approximately equal to that received ___
The atmospheres average temp would change
Combined albedo of Earth and the atmosphere is approx ____ %?
30%
Clouds strongly emit infrared radiation back to the Earths surface, T or F?
True
Suppose last night was clear and calm. Tonight’s forecast indicates that low clouds and fog will be present. From this you would conclude that tonight’s minimum temperature will be ?
Higher than last nights minimum temperature
The heat energy released when water vapor changes to a liquid is called?
Latent heat condensation
The albedo of the moon is 7%, this means that?
7 % of sunlight striking the moon is reflected
Without the atmosphere greenhouse effect, the average surface temperature would be ___?
Lower than at present
The amount of heat energy required to bring about a change in temperature in a substance is called?
Heat capacity
Which principle bets describes why melting occurs first in snow around tree trunks?
Snow is a good absorber of infrared energy
When water vapor evaporates, latent heat is reversed into the atmosphere, this provides a tremendous amount of heat in storms, such as thunderstorms and hurricanes. True or False?
False
Earth emits radiation with greatest intensity at ?
Infrared wavelengths
The atmosphere near earths surface is “heated from below” by heat energy from earths interior. True or false?
False
The main process responsible for warming in the lower atmosphere is?
The absorption of infrared radiation
The sun emits its greatest intensity of radiation in ?
The visible portion of the spectrum
What determines the type (wave length) and amount of radiation an object emits?
Temperature
Sunlight that bounces off a surface is said to be ——- from the surface
Reflected
A vertical exchange of heat is called?
Convention
As we apply Newtonian principles and analyze the way the suns energy travels through the atmosphere we can say that solar radiation reaches earths surface as?
Ultra violet, visible, and infrared
Often before sunrise on a clear, calm morning, the temperature falls dramatically in the absence of parked cars, even when the air temperature is above freezing because the tops of cars are cooling by a loss of?
Radiation
The rising air bubbles from convection are known as
Thermals
During the formation of clouds what is released as sensible heat?
Latent heat
