What is remanent magnetism? How can it be used to track the movement of continents over time?
Eddies- Identify the circumstances under which eddies may form. Recognize warm and cold core eddies by their core temperatures. Investigate the mechanism by which eddies transport water masses and marine life to the surface of the ocean. Ocean production may be affected by the variety of patterns of convergence and separation generated by eddies.
