Wind and Ocean Current Notes
Thermal Energy-
Heat- Energy that make molecules move.
Temp.- measurement of the motion of molecules
Transferred from a hotter substance to a colder substance
THERMAL ENERGY TRANSFER
radiation-
direct transfer of energy transfer from the sun
travels in electromagnetic rays which is the only thing that can travel through empty space, (infared radiation)
transfered to heat energy
conduction-
transfer of heat through direct contact
solids cunduct more heat
liquids conduct less heat
convection-
transfer of heat by the fluid movement of molecules in solids, liquids, and gasses
cold air pushes warm air higher
warm air rises
cold air sinks
-- infared radiation from the sun is absorbed by earth's surface
-- the surface then converts the radiation into thermal energy
-- thermal energy heats up the earth and air.
-- warm air rises and cold air sinks, creating a cycle
-- water is cooler because the land takes a shorter time to heat up and cool off, while the water takes a long time to heat up and cool off
-- warm air is less dence than cold air, which is more dence
-- warm air created a low pressure, while cold air is more dence so it makes a high pressure area
global winds-
the air around the equator is heated the most, it starts raising up through the trotosphere,then it moves north and south, away from the equator
known as trade winds
prevailing winds- winds above the surface that follow a specific direction year round
OCEAN CURRENTS-
are created by global winds, salinity, and convection
salinity is the amount of saltyness in the water
driven by earth's rotation
clock wise movement in north, counther clockwise in south
the suns energy causes convectional movement of water
both deep and surface ocean currents
colder water is salty, making it more dence
Coriolis effect-
the force due to earths rotation that causes prevailing winds to change direction.
