In mid-ocean, the characteristics of a wave are determined by three factors. What is NOT one of these factors?

Correct Answer: Option A — Effect of the moon's gravity

Wave characteristics in mid-ocean are governed by wind velocity, duration, and fetch. The moon's gravity influences tides, not the generation of wind-driven waves. Bowditch defines these three meteorological factors as the primary determinants for sea state development, excluding gravitational tidal forces from the wave-generation process in deep water.
