Heat
HEAT is a transfer of energy from warmer to cooler substances.
There are 3 types of heat transfer:
Occurs in SOLIDS
Change of state from SOLID to LIQUID
Freezing
In order for conduction to occur, the molecules MUST make CONTACT!
Occurs in FLUIDS only! (Never in SOLIDS)
Fluids include BOTH:
Example: The WATER in our oceans.
CHANGES OF STATE WITH LIQUIDS
LIQUID TO GAS
GAS TO LIQUID
LIQUID TO SOLID
SOLID TO LIQIUD
Example: The AIR in the atmosphere

where warm fluids always rise
where cold fluids always sink
this creates CURRENTS (convection currents!)
Radiation
The source of energy for radiation is the SUN.
Radiation travels by electromagnetic waves
There are many types of electromagnetic radiation
VISIBLE LIGHT
"IR" Radiation
"IR" stands for....
Radio waves
X-Rays
"UV" Radiation

UV Radiation is blocked by the OZONE in our atmosphere
OZONE is located in which layer of the atmosphere?
heat is how ENERGY is transferred
