conduction
a frying pan on the burner (convection, conduction, or radiation)
conduction
heat that is moved or transferred between two objects that are not touching.
radiation

radiation
heat is transferred from the _____ (warmer or colder) object to the ______ (warmer or colder) object
warmer, colder
air is lighter and will rise (warm or cold)
warm

during the ____, heat rises over the hot landmass and falls over the cooler ocean.
day
what causes ocean currents?
convection currents (heat rising and cool air falling)
during the _______, heat rises over the warmer ocean and falls over the cooled landmass
night
______ ____ flow within the mantle which causes the tectonic plates to move.
convection
_______ ________ flow within the ocean and cause the ocean’s currents.
convection currents
