Exam 15: Shorelines and Shoreline Processes

Large-scale surface water circulation systems in the oceans are known as ____________________.

Winter beach profiles can actually develop during any season.

A coast that is straight and has marine terraces is a(n):

High costs and the detrimental effect on the ecology of estuaries render the construction of tidal power plants unsuitable for many areas.

The distance from one crest (or trough) to the next in a wave is the ____________________.

The tiny shells of marine organisms form marine sediments called:

How do rip currents form, and what should you do if you are caught in one?

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 are longshore currents, and how do they form? Why are they important to shoreline processes?

The distance wave-producing winds blow over a continuous body of water is the:

Barrier islands migrate landward.

A region with an emergent coast is Scandinavia due to isostatic rebound.

What characteristics along a seacoast indicate that erosion predominates over deposition?

Describe how a coast can become emergent.

Outline and describe factors that are responsible for global surface circulation patterns. Where are the cold and warm water currents and how do they moderate Earth's temperature?

The most effective means of sea cliff erosion is hydraulic action.

What are the two factors that control the absolute rate of sea level rise in a particular shoreline?

The average salinity of seawater can be expressed as ____________________ grams per kilogram of seawater, ____________________ parts per thousand, and ____________________ percent.

The rising tide is also known as the ____________________ tide. The falling tide is known as the ____________________ tide.

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