When there are small differences between the heights of two successive high tides or two low tides, in a tidal day, the tides are called _______________.
AI Explanation
The correct answer is B) semidiurnal.
Semidiurnal tides are characterized by two high tides and two low tides of roughly equal height each day, with small differences between the heights of successive high tides or low tides. This is in contrast to diurnal tides, which have only one high and one low tide per day, or mixed tides, which have two unequal high and low tides per day.
The small differences in height between successive high or low tides are a defining characteristic of semidiurnal tides, which are the most common type of tidal pattern observed along the coasts of the United States. The other answer choices do not accurately describe this tidal pattern.
