D)and wave height increase as wave speed quickens.

Question

Quizplus · Accepted Answer

As a swell approaches the shore and touches the bottom, its wavelength shortens due to the decrease in water depth, the wave speed slows down, and the wave height increases because the energy of the wave is compressed into a smaller volume of water, causing the waves to grow taller.
