1. The Atmosphere:
Quick Review

2. Temperature v. Heat
Temperature: measurement of the motion of atoms or molecules faster motion = higher temp
Heat: the transfer of energy from one object to another flows from higher to lower temp
Three main types of transfer: convection, conduction, radiation,
Heat fuels the weather, and temperature measures it!

5. Conduction Example: A pot touching a hot stove.
The transfer of heat through direct contact
Example: A pot touching a hot stove.
Example: Touching a cold ice cube.

6. Convection
The circular transfer of heat through fluids (liquids & gases).
Warm air rising
Cold air sinking

7. Radiation Example: The warmth you feel from the sun.
Example: Sitting around a campfire.
The transfer of energy through space
All objects, at any temperature, emit radiant energy

Temperature Controls: conditions that change temperature from one place to the next
Example
latitude

19. Land and Sea Breezes Why is the beach warmer?
Cooler air is drawn on shore by what process?
Convection causes a cool wind to blow on shore

20. Land and Sea Breezes Which will cool off faster? Land or Water?
The warmer water draws cool air from land
At the beach at night you will experience a warm breeze

21. Isotherms
 Isotherms are lines on a weather map that connect points where the temperature is equal.
Isotherms show the effects of temperature controls, such as latitude, altitude, distribution of land and water, and ocean currents
