During a hurricane or other strong coastal storm, material on barrier islands can be moved from the seaward side to the side away from the seat in the process called

overwash

What geologic event is probably indicated by this a regular coast, with estuaries?

A rise in sea level

Which of the following does not affect the potential hazards of a shoreline?

All of these affect potential hazards of shorelines

What is the main way that position of the continents can influence global sea level?

Continent at higher latitudes provide a setting in which large ice sheets can form

What is the primary reason an increase in glaciers on land will cause sea level to fall?

Glaciers tie up large volumes of water that would otherwise be in the sea

The image shows a coastline that

Has undergone a rise in relative sea level

The diagram below represents a model that the US geological survey uses to categorize the extent of storm surge in the coastal zone. The red arrow in this figure points to

Maximum height of the swash zone

What was a key point demonstrated by photographs in the textbook from before and after hurricanes?

Waves and storm surge caused erosion of beaches and destruction of houses.

An increase in the rate of seafloor spreading along this ridge would cause

all of these choices are correct

Which of the following would cause the level to rise?

all of these choices are correct

Which of the following most likely indicates that sea level has fallen relative to the land?

all of these choices are corrext

Which of the following most likely indicates that sea level has risen relative to the land?

an irregular coastline with branching estuaries and embayments

How does the rate of seafloor spreading affect sea level?

faster spreading produces broader ridges that displace water out of the oceans

What is probably the least expensive approach for avoiding shoreline hazards?

forbid the building of houses or other structures in high-risk areas

Which of the following is not an approach communities have tried to address shoreline problems?

lowering the local sea level
