Answer to Question 1ANS: C
The wave train travels at half the speed as individual waves in the train. This is called the group
velocity. This is the speed at which energy advances in the ocean. Information can be found in the
section Wind Blowing Over the Ocean Generates Waves.
Answer to Question 2ANS:Answer
should include:
Some organisms live in intertidal zones. These organisms are subject to various
conditions of submergence and emergence. They develop ways to deal with desiccation.
The organisms that utilize the intertidal zone separate out into a layer which is suitable
for their need for water.
Some organisms migrate vertically with the tides. These organisms often find shelter in
sediments during high tides. This could be protection from wave action or predation.
There are organisms that rely on tides to bring food and nutrients to them. This is true of
many filter feeders. These animals would not be able to get enough nutrients to survive
without the tides.
Animals like the grunion use the tides to reach the shore for breeding. This behavior
occurs the day after the highest spring tides. This breeding mechanism provides
protection to the developing eggs from voracious marine predators.
