Tidal range is the vertical difference between the high tide and the low tide, which can vary significantly depending on the location and the phase of the moon. Tidal range is significant in oceanography and coastal geology for understanding the dynamics of tides, the formation of tidal currents, and the impact of tides on coastal environments.
