1. What is climate? TIME How does climate differ from weather?
Weather: Hours to weeks
Climate: Months to millenia

2. What characteristics does a climate have?
Air temperature
Humidity
Precipitation (type & amount)
Wind (speed & direction)

3. What Affects Air Temperature? (at climatic time scales)
Unequal amounts of solar radiation
(axial tilt, seasons, etc.)
Unequal heating of land & water
Altitude (cooler at higher elevations)
Geography (esp. regarding winds)

8. Land vs. Water Land Water Land has a lower specific heat than water.
(Specific heat: Energy to raise 1 gram of a substance 1°C)
Therefore,
