  When ocean water is cooled by air and the water temperature 
  drops to - 1.8 °C (28 °F) the sea begins to freeze...
  Ice crystals will appear in the water and float to the surface. 
  As the number of these increases, they congregate to form 
  a soupy layer on the surface.
  When there is wind and waves, continuous sea ice does not 
  form directly. Patches of ice are formed which then coalesce 
  and thicken to form a vast expanse of ice ... called SEA ICE !
       Find and trace the outlines of the four patches of ice 
  that have come together to form the sea ice in the drawing !
  ! ! ! Be careful, all the ice patches are the same shape ! ! !
         They all have 4 different polar animals on them.
