Where marks usually go

  • Listing currents without explaining the forces
  • Not giving a single fishing ground example

Draw this

  • World map of major currents and fishing grounds

Value addition

  • ExampleGrand Banks off Newfoundland are rich because the warm Gulf Stream meets the cold Labrador Current.NCERT Fundamentals of Physical Geography
