Exam 10: The Restless Ocean

Although the Sun influences the tides, its gravitational effect is considerably less than the effect of the Moon.

Erosional retreat of a(n)________ leads to enlargement and extension of a wave-cut platform in the inland direction.

Beach drift and longshore currents only develop when waves' direction of approach is perpendicular to the shoreline.

________ are huge circular-moving current systems that dominate the surface of the ocean within an ocean basin.

To measure wave period, the best tool to use would be a ruler.

Large estuaries are more common on a(n)________ coastline.

Does this photograph show a tombolo, a barrier island, a sea arch, or a marine terrace? ________

A ________ is an isolated remnant of bedrock standing above a wave-cut platform.

________ is the rising of cold water from deeper layers to replace warmer surface water.

Chesapeake Bay and Delaware Bay are ________.

________ are low-lying zones that are alternately covered by water during flood tide and exposed following ebb tide.

Examine the figure and use the information provided there to explain the different temperature trends seen in Arica and Rio de Janeiro.

As a deep-water wave enters shallow water, the part of the wave in the most shallow water slows down. The deeper-water portion of the wave crest keeps moving at a relatively rapid speed. This wave refraction causes the entire wave crest to progressively rotate toward being ________ with the shoreline.

If uplift of the land occurs, a wave-cut platform may become a new ________.

Spring tides occur in conjunction with the full Moon or the new Moon.

Examine the figure. Identify and label each of the lettered locations with the name of the shoreline feature shown there.

Which of the following is an example of "hard stabilization" designed to prevent or retard shoreline erosion?

Describe some of the options available to people when it comes to coping with erosion along shorelines.

Examine the figure. Identify the type and describe the tidal patterns observed over the course of a day in three U.S. cities: San Francisco, California (SF), New Orleans, Louisiana (NO), and New York, New York (NY).

The energy that drives surface ocean currents such as the Gulf Stream comes from ________.
