- - - - GRAVITIONAL PULL MOON &CENTRIFUGAL FORCE
  - - - DIURNAL=(1HT,1LT)/day
      - MIXED TIDE=varitions height
        
        west coast NORTH AMERICA
      - SEMI-DIURNAL =(2HT,2LT) /day
    - - SPRING TIDES
        
        sun,moon,earth=straight line|||| tide higher
        
        gravitional pull moon is enhanced by gravitional pull sun
        
        twice month--full moon & new moon
        
        high tides higher than normal;;;low tides lower than normal
      - NEAP TIDES
        
        sun&moon right angles==low tides
        
        sun pull dimnishes moons pull
        
        7day interval=btwn (spring&neap tides)
        
        twice=month
        
        high tides lower than normal;;low tides higher than normal
