The term 'ocean-wave' is composed of two words, 'ROLLER' and 'BREAKER'. The word 'ROLLER' is a 6 letter word that describes a wave that moves in a circular motion, while the word 'BREAKER' is a 7 letter word that describes a wave that crashes against the shore. Ocean-waves are created by the wind blowing across the surface of the water, creating ripples that eventually become larger waves. These waves can be seen on the shoreline, where they break against the land and create a sound.
