Crests are the highest points of waves, where the water reaches its maximum elevation before crashing down. They are formed by the wind's energy transferring to the water, creating ripples that grow into larger waves. The crest is often seen as the peak of the wave, and it plays a crucial role in the dynamics of ocean currents and coastal erosion. In heraldry, a crest is also a symbol that appears above a coat of arms. It typically represents a family, organization, or nation and is often depicted as a figure or emblem. Crests in this context can include animals, objects, or other designs that convey specific meanings or values associated with the entity they represent.
