Question 2017Navigation General

The correct answer is C) range. The range of the tide refers to the difference in height between the low tide and the high tide at a given location. This is a key concept in understanding tidal patterns and is an important factor for Coast Guard operations, such as planning boat operations, navigation, and docking. The other answer choices are incorrect because: A) Distance refers to the horizontal measurement between two points, not the vertical difference in tide heights. B) Depth refers to the vertical distance from the surface to the seafloor, not the difference between low and high tide. D) Period refers to the time between successive high or low tides, not the difference in their heights.
