19.  Given a graph of sea-surface temperature or ENSO index, determine general trends in climate that are likely to occur California in a given year.

20.  Describe and identify on a figure the equatorial current, polar jet, and subtropical jet during El Niño and normal conditions.

21.  Correctly indicate of we are currently in El Niño or La Niña conditions.

22.  Indicate the projected outlook for climate in the US over the next 3 months.

23.  Describe what principle or principles are illustrated by the "Daisyworld" simulations.

24.  Explain why the growth of daisies in "Daisyworld" changed the temperature of the planet.

25.  Relate a graph of daisy population to a graph of temperature on “Daisyworld.”

26.  Explain what is meant by a “self regulating” system; give examples of self-regulating systems.

27.  Relate Daisyworld to general observations about the temperature and chemistry of Earth.

28.  Define and correctly use the terms “adiabatic cooling” and adiabatic warming.”

29.  Given photographs or sketches, correctly identify the following types of clouds: Cirrus, Altostratus, Stratus, Cumulus, Cumulonimbus, Stratocumulus, Altocumulus, Nimbostratus, and indicate if they are High Clouds, Middle Clouds or Low Clouds.

31.  Describe the formation of and correctly identify the following types of precipitation: Rain and Drizzle, Snow, Sleet and Hail.

32.  Explain how the position of the Sun, Earth and Moon give rise to different phases of the Moon.

33.  Given the position of the sun and moon relative to Earth, predict the phase of the moon.
