Radiation
10
Prove this statement: Infrared radiation is weaker than visible light.
12
Radiation Maximum Energy from the Sun is in the form of Visible Light (Short waves)
13
Maximum Energy RE-RADIATED from the Earth is in the form of Infrared (longer waves)
14
Black and rough absorbs the best
If it is a good absorber….it is a good radiator (re-radiation)
15
White (shiny) and smooth is the best reflector
Energy absorbed and released by the Earth is called terrestrial radiation
16
What could block(scatter and reflect) or absorb it?
Aerosols and dust in the atmosphere Water vapor and CO2 Volcanic ash

AIM: ATMO ENERGY PRE-TEST DO NOW: 1
AIM: ATMO ENERGY PRE-TEST DO NOW: 1. PERIOD 4 AND 9 TAKE OUT YESTERDAYS LAB DATA 2. PERIOD 1 AND 7 TAKE A TEST ESRT. YOU MAY USE YOUR OWN CALCULATOR. HW: STUDY FOR MIDTERM ENERGY TRANSFER TEST WIZARD DUE NEXT FRIDAY AT 8AM
24
CONDUCTION Energy transfer by direct molecular contact
Most common through a solid object Can occur when a solid object TOUCHES the molecules of another solid, liquid (Metal bar in water) or gas
26
Convection Transfer of heat through fluids (liquids, gases and magma)
Results from differences in density within the fluids
27
The differences in density could be caused by changes in both temperature and/or pressure
28
Ex: warm air rises, cool air sinks
Creates a CONVECTION CELL
30
Which example of heat transfer is due mainly to convection?
Heat energy transferred by air moving from the Earth's surface to the upper atmosphere Heat energy transferred by being reflected from a lake surface to the air above Heat energy transferred through a solid metal door Heat energy transferred from the Sun to the Earth
31
