Thermal Heat:
Infrared Radiation from sun is absorbed
by the Earth and released as HEAT.
Thermal Energy Transfer:
Radiation, Convection, Conduction
Radiation: Direct transfer of energy from the sun
Convection: Transfer of heat by the movement of molecules in liquids and gases.
Conduction: Transfer of heat through direct contact.
Thermal energy heats up the air at the surface causing temperature.
Warm air is less dense than cold air. Since air is a
fluid the warm air is pushed up by the cold air. Convection, warm air to rises and cold air to sinks. This is a cycle.
When warm air rises it creates a low pressure area. When cool air sinks it creates a high pressure area.
Coriolis Effect:
The force due to the Earth's rotation that cause objects in motion to veer to the right in the Northern Hemisphere and
to the left in the Southern Hemisphere.
Prevailing Winds:
Global winds that can be predicted based on the latitudes of the earth.
Ocean Currents:
Currents are created by global winds, salinity, and convection.
Convection In Currents:
Sun energy causes convective movement
of the ocean water
Heat from the sun causes differences
in the density of the water.
