This is the second assessment for waves. Some of the questions may seem familiar as they are a second chance for you to improve on previous concepts. Good luck!

Waves Assessment 2

Waves are the transfer of energy through the ocean.

Grunions are small fish that swim onto the beach in order to lay and fertilize eggs. Two weeks later the eggs hatch and the offspring find their way into the ocean. These mating rituals are closely related to the lunar phases. Which phases of the moon would provide the best possible time for (a) the grunions to lay their eggs and (b) for the eggs to hatch. Justify your choices. * Grunion
