Module 12 – Continental Shelf Communities

The Continental Shelf is a gently sloping area, beginning at a point near land, just below the low-tide mark.  It continues out to the shelf break, which is the outer edge of the continental shelf.  This area contains abundant  quantities of life are are vast fishing grounds.  We have just studied Coral Reef communities.  They are located on the continental shelf, but because they are specialized, we studied them separately.        (Module 11- see previous posts.)
