Exam 15: Oceans, Shorelines, and Shoreline Processes

A spit that connects an island to the mainland is a:

Sea level could change relative to a shoreline due to:

What are two ways (one natural and one human-induced)in which the sediment budget of a coastline can become negative?

How does the Moon generate tides? Why are there generally two high tides and two low tides a day?

Vertical ocean circulation is the result of differences in what between adjacent water masses?

Coriolis effect is the deflection of freely moving bodies,such as air or water molecules,that results from Earth's rotation.

The tiny shells of marine organisms create a marine sediment called

Briefly explain how sea level could fall in one region while it is generally rising elsewhere.

Describe how a coral atoll forms.

What is an Exclusive Economic Zone (EEZ)?

The velocity of a wave is calculated as the ____________________ multiplied by the ____________________.

Briefly explain what the effects of rising sea level are on the barrier islands along the United States coastlines and why coastal communities are concerned.

What two phenomena cause the tides? Which of these is stronger,and why?

Give a possible reason why beach residents might construct a groin on a beach.What is a probable negative effect of such a construction?

What is a wave-cut platform,and how does one develop?

Tides that occur when the Sun and Moon are at right angles to one another and have wave-generating abilities that cancel each other out are ____________________ tides.

The diameter of a water molecule orbit increases with depth until the wave reaches the seafloor.

Winter beach profiles can actually develop during any season.

Narrow surface currents that flow in the same general direction as the approaching waves are:

Methane hydrates could provide a lot of energy for us to use.Outline the reasons that these resources are not yet being used.
