Answer:
Whitecaps
Step-by-step explanation:
Tsunamis are giant waves, sometimes reaching heights of over 100 feet (30.5 meters), caused by earthquakes or volcanic eruptions under the sea.
A fetch is an area of ocean or lake surface over which the wind blows in an essentially constant direction generating waves.
A crest is the point on a wave with the maximum value of upward displacement within a cycle.
Whitecaps are waves that grow too high for their bases, therefore they collapse quickly and lose their energy forming a whitish foam.
