Definitions 1
temperature
The measure of the average kinetic energy
insulator
Poor conductor of heat
mechanical energy
The energy possessed by an object due to its motion and position
GPE=MGH
GPE= (kg) (10m/s) (meters)
How does air move?
Due to density differences from uneven heating of earth rotation and areas of high to low pressure
deep current
movements of ocean water far below the surface
convection
The transfer is due to the movement of matter
kinetic energy
The energy of an object due to its motion
KE=1/2mv2
KE= (1/2) (mass) (velocity) 2
trade winds
east to west 0*-30*
thermal expansion
The increase in volume that results from an increase in temperature
conduction
The transfer of energy from one object to another through direct contact
potential energy
Energy and object has due to its position condition or chemical composition
Easterlies
east to west 60*-90*
Convection cells
The less dense air goes up, the more dense air goes down also known as uneven heating, which cause wind
thermal energy
The total amount of kinetic energy
Jet stream
narrow belts of high-speed winds that blow from west to east 7 km to 16 km above earth
Renewable resource
solar energy
hydro electric
wind
biomass
Westerlies
west to east 60*-30*
what are the three factors that affect surface currents?
continental deflections
the Coriolis effect
global winds
radiation
The transfer of energy through electromagnetic waves
The Coriolis effect
The deflection of moving objects from a straight path due to earth rotation
nonrenewable resource
coal
oil
petroleum
uranium
what is the law of conservation of energy?
Energy cannot be created or destroyed they can only change form
Global winds
when the systems occur or near earth surface
