70% to passA swift current occurring in a narrow passage connecting two large bodies of water, which is produced by the continuously changing difference in height of tide at the two ends of the passage, is called a _______________.
You are correct, the answer is A) hydraulic current. A hydraulic current is the term used to describe a swift current that occurs in a narrow passage connecting two large bodies of water, such as a strait or inlet. This current is produced by the continuously changing difference in the height of the tide at the two ends of the passage. As the tide rises and falls, the water is forced through the narrow channel, creating a strong, unidirectional flow. The other answer choices are incorrect because: B) harmonic current refers to the regular, predictable pattern of tides, C) rotary current describes a circular current pattern, and D) rectilinear current refers to a straight, linear current flow.
