Tsunamis are long, powerful ocean waves caused by underwater earthquakes, volcanic eruptions, or landslides. The waves can travel across the open ocean at high speeds, often undetected. In the open ocean, tsunamis are characterized by relatively small amplitudes (heights) and long wavelengths (distances between wave crests).
As tsunamis approach the shallow coastal areas, they experience a phenomenon called "shoaling." The decrease in water depth causes the wave to slow down and increase in height, resulting in large and destructive waves near the shore.
To answer this type of question, it is helpful to have background knowledge about tsunamis and their behavior. Understanding the physics of wave propagation and the effects of shoaling on wave characteristics will allow you to make an informed choice. It is important to study and gather information about different types of waves, their formation, and their behavior to answer such questions accurately.
