The perigee and apogee are points on the elliptical path of the Moon's orbit around the Earth.

The first commercial wave power plant is called the 'Limpet 500'.

For a tidal generating station to be effective, it must efficiently convert potential energy into electrical energy.

When the Earth-Moon system is aligned with the Sun, the moon is said to be Apoplexy.

The speed of a wave is its wavelength divided by its period.

When a tsunami wave comes ashore, the first thing that happens is it slowly floods inland.

The largest ocean wave measured to date was 34 m in wave height.

Waves refract 'into' headlands and 'away' from beaches.

The tidal station recording the lowest tidal range is Burntcoat Head, Nova Scotia.

A Neap Tide is when the moon is oriented perpendicular from the Earth to the Sun.
