21. Based on the plotted predicted data for the two days, the vertical distance etween 1g es 1g and lowest low tide at Fernandina Beach was about _ ft. a. 0.5 b. 5.5 C. 6.4 22. The water level data for Cedar Key appears in the bottom graph in Figure 2. According to the water level curves, Cedar Key experiences _ high tidels)I and the same number of low tideis} each day. a. 0 b. 1 c. 2 23. The Cedar Key predicted water level curve is characterized by considerable variation in successive high tides andfor successive low tides. Consequently, the tides at Cedar Kev are described as _. a. diurnal b. semidiurnal c. mixed 24. Figure 3 shows a tide gauge station and the locations of the three tide sites {names underlined in yellow] along the Florida coast. Their predicted tides differ greatly in type and range. These contrasts can primarily be attributed to differences in _. a. their geographical settings b. the astronomical forces acting on them. 25. The primary cause of the differences between predicted and observed tide heights, as most dramatically seen in the cedar key graph in Figure 2, is almost always in orgin. a. astronomical b. seismic
