Close, a place can't have spring tides, but instead South Africa has semidiurnal tides.

Reviving this thread:

What is the difference between catadromous and anadromous sea organisms?

Chris_L · Post by **Chris_L** » Wed Apr 22, 2015 8:30 am

Catadromous species live in freshwater for the most part and spawn in salt water, while anadromous species live for the most part in salt water and spawn in fresh water.

Correct! Your turn to post a question.

How is a hotspot formed? What do they leave behind as the crust above them moves? (Assume these hotspots are located in the ocean.)

Answer (Click to Show Hidden Text)

Hotspots form from the outer core where mantle plumes rise and extrude at the surface, creating a shield volcano in the ocean. As the plates move, the hotspot is in the same location so a chain of volcanic islands, aka an archipelago, is left behind. EXAMPLE: Emperor Seamount Chain (Hawaii)
