1. Essential Question: How and where do the 5 types of fog form?

2. Bell work: What are two ways to increase humidity to 100% 1. 2.

3. 2 Types of Fog Fog that forms by Cooling (lowering temps.) Radiation Upslope Advection Fog that Forms by Evaporation (adding moisture) Steam Frontal/Precipitation

4. SHORT wave solar energy is absorbed by the Earth and then re-radiated as LONG wavelength infrared (heat) waves. Earth’s atmosphere is heated from the GROUND UP.

6. Radiation / Valley Fog

8. Convection Transfer of heat energy through vertical movement of air (flow) Horizontal flow of air A.k.a. “wind” Advection
