Answer to Question 1

ANS: C
The high tides and low tides of semidiurnal mixed tides are significantly different from one another.
This pattern is the result of the blending of diurnal and semidiurnal tidal patterns in the region.
Information can be found in the section The Dynamic Theory of Tides Adds Fluid Motion Dynamics to
the Equilibrium.



Answer to Question 2

ANS: B
The moon is much closer to Earth than the sun is. The sun's influence on tides is only 46 that of the
moon's influence. Information can be found in the section Tides Are the Longest of All Ocean Waves
