Foamy waves are a type of wave found in the ocean. Whitecaps, which are nine letters long, are the small, foamy crests that form on the surface of the water when the wind blows across it. BREAKERS, which are eight letters long, are larger waves that form when the wind and tide combine to create a powerful force. Both whitecaps and BREAKERS can create foamy waves, which are characterized by their white, bubbly appearance.
