path water takes through its various states, as it moves throughout oceans, streams and the atmosphere
phase change from liquid to gas
phase change from gas to liquid
visible groups of tiny water droplets and or ice crystals in the atmosphere
solid or liquid water that fall from the atmosphere and reach earths surface
movement of water along earth's surface
movement of water INTO earths surface
transfer of thermal energy by waves moving through empty space
which heats up faster? a black or white t-shirt?
a good absorer of energy is also...
a good releaser
material that conducts thermal energy well
example of thermal conductor
pots and pans
material that poorly conducts thermal energy
example of thermal insulator
air, wooden spoon
transfer of thermal energy in gases and liquids by direct contact of particles
gas or liquid
as temperature increases, density...
as temperature decreases, density...
example of convection
air from a heater warms the room
fluid circulates in a loop as the fluid heats up and cools down
sunlight reaching earth
a tea kettle warming on a stove
the water throughout the tea pot warms
why does lead heat up faster than liquid water?
lead has a lower specific heat
why does liquid water heat up slower than lead?
liquid water has a higher specific heat than lead
3 places where convection is occuring the earth
planetary winds, ocean currents, asthenosphere
why did the red dye rise?
the cool water made the dye's density decrease
why did the blue dye sink?
the warm water made the dye's density increase
which heats up faster? land or water?
land-lower specific heat
which cools down faster? land or water?
land-good absorber is a good releaser
transfer of thermal energy in solids by direct contact of particles
