Waves and Tides
  1. Constructive waves
    1. Frequency: 6-9 waves per minute
      1. Stronger swash than backwash
        1. Long wave period
          1. Low flat waves
            1. Flat wide beach
              1. Wavelength: large 100m crest-crest
                1. Low energy (deposition)
                2. Destructive waves
                  1. Frequency: 11+ waves per minute
                    1. Stronger backwash than swash
                      1. Short wave period
                        1. Tall steep waves
                          1. Steep beach
                            1. Wavelength: small 20m crest-crest
                              1. High energy (transportation)
                              2. Spring tide
                                1. Tidal range at its largest
                                  1. The moon is between the earth and the sun
                                    1. Gravitational pull combines creating biggest bulge of water and largest tide
                                      1. Highest high tides
                                        1. Lowest low tides
                                      2. Neap tide
                                        1. Small tidal range
                                          1. The earth, moon and sun form a right angle
                                            1. Gravitational fields interfere
                                              1. Lowest high tides
                                                1. Highest low tides
                                              2. Tides are the periodic rise and fall in the level of the sea
