Answer to Question 1

ANS: C
The difference between aphelion and perihelion, the shortest and greatest distance from the sun, is
approximately 3.7 million kilometers. The distance of both the sun and the moon can have profound
effects on the tides. Information can be found in the section Tides Are Forced Waves Formed by
Gravity and Inertia



Answer to Question 2

ANS: B
The grunion come in just after the highest spring tides to deposit and fertilize eggs. This provides
protection to the eggs from marine predators while they develop. Information can be found in the
section Tidal Patterns Can Affect Marine Organisms
