Refers to the uninterrupted passage of shortwave and longwave energy through either the atmosphere or whater
transmission
flow of kinetic energy between molecules and from one body or substance to another resulting from a temperature difference between the,
heat
can be “sensed” by humans as temperature because it comes from the kinetic energy of molecular motion
Sensible heat
Hidden Heat. Energy gained or lost when a substance changes form one state to another such as from water vapor to liquid water ( gas or liquid) or from water to ice
Latent Heat
transfer of heat in electromagnetic waves
Ie. from sun to earth or fire burner on the stove
radiation
Shortwave length moves toward
earth
longwave moves towards
atmosphere
a balance sheet of energy income & expenditure
budget
ultraviolet light, visible light, & near infrared wavelengths
shortwave inputs
thermal, infrared wavelengths
longwave outputs
is the energy budget the same everywhere?
since solar energy is unevenly distributed by latitude & fluctuates seasonally the energy budget is not the same everywhere even though it is in equilibrium
the hotter an object the _____ the wavelengths that are emitted
shorter
do waves of radiation need to travel through a medium in order to transfer heat?
no
_____ of an object determines wavelength of radiation it emits
temperature
molecule to molecule transfer of heat energy as it diffuses through a substance
conduction
as molecules warm, their ______ increases, causing collisions that produce motion in neighboring molecules, thus transferring heat from warmer to cooler material
vibrations
example of energy conducted
through handle of pan on kitchen stove
different materials conduct sensible heat directionally from areas of _______ temperature to those of _____ temperature
higher, lower
general term describing the pollution related decline in insolation to earths suraface
global dimming
