How did the oceans form?
What is salinity?
What dissolved solids can be found in ocean water?
Salinity-climate relations. (warm & dry; cool and humid)

How/why does the temperature of the surface zone vary during different times of the year (excluding waters near the
equator)?
How does the ocean regulate temperatures in the atmosphere? (What unique property does water have?)
Describe the water cycle.

Describe each of the following ocean floor regions/features:
A. continental margin
B. deep-ocean basin
C. continental shelf
D. continental slope
E. continental rise
F. abyssal plain

What are surface currents? What causes them?
What 3 factors can affect surface currents? Describe each.
What are deep currents?
Describe the formation and movement of deep currents (Fig. 7 & 8 in text)
Compare the size and speed of surface and deep currents.
Explain how warm-water currents affect climate. Use Gulf Stream as an example.
Explain how cold-water currents affect climate. Use California Current as an example.
What is El Nino?
Describe some effects of El Nino.
Explain why and how scientists study El Nino.
Describe the two types of waves.
How do most waves on the ocean’s surface form?
What are breakers?
Describe the following parts of a wave: (include a diagram for clarification)
A. Crest
B. Trough
C. Wavelength
D. Wave height
E. Wave period
How do most waves form? (describe the role of wind intensity and duration in forming waves).
Compare and contrast undertow and longshore currents.
What causes tides? (Earth-Moon-Sun dynamics)
What determines when tides occur? (Why are they not at the same time everyday?)
Compare and contrast Spring Tides and Neap Tides.
What is a tidal bore?
