Motion of the Ocean
Waves can have a wide range of movement from peaceful to destructive. In my book I showed the different ways ocean waves are used, from generating power to tearing down whole cities.
My book has 5 chapters and each chapter is named after a part of a wave (resting point, through, amplitude, crest, and wavelength). From chapter 1 (Resting Point) to chapter 4 (Crest). The chapters increase in columns, thicker fonts, and larger pull quotes to give the illusion of water building up and causing a sense of panic by the time you get to Chapter 4.
