As a wave approaches shore, it becomes unstable due to the bottom causing the wave height to rise and spill its energy. True or False?

As a wave approaches the shore, it interacts with the bottom topography, causing changes in its stability. This phenomenon occurs as the wave enters shallower water. The energy of the wave begins to compress, resulting in an increase in wave height. As the wave height increases to a point where it can no longer be sustained due to gravity, it spills over, creating what is known as a breaking wave. This process demonstrates how the wave transforms as it moves toward the shore, confirming the statement's accuracy. Therefore, the assertion that waves become unstable and spill their energy as they approach the shore is true.
