Question 3

Beaches are generally wider in the summer than in the winter.

Accepted Answer

A) True 
 B)False

Question 4

In what time of year do beaches get smaller?

Accepted Answer

A)   spring
B)   summer

Question 5

Explain the origin, travel, and shoreline actions of a tsunami.

Accepted Answer

Tsunamis are generated by large underwater (usually) earthquakes. These send out much energy in very long wavelengths in ocean water. When the tsunami approaches the shore, the shallowing of the sea bottom interacts with the waveform sometimes translating it to very tall heights which disastrously crash on the shore.

Question 6

Generally, ________ waves are gentle phenomena.

Accepted Answer

A)   oscillation
B)   translation
C)   seismic sea
D)   forced
E)   breaker

Question 7

Most waves approach the coast parallel to the coast.

Accepted Answer

A) True 
 B)False

Question 8

Coral is usually localized in areas having relatively cool ocean currents in Tropical Latitudes.

Accepted Answer

A) True 
 B)False

Question 9

Which of the following is NOT a necessary condition needed for the growth of coral?

Accepted Answer

A)   warm water
B)   saltwater
C)   the presence of tiny marine animals
D)   shallow water
E)   the presence of an underwater volcano

Question 10

Which of the following is most closely associated with fjords?

Accepted Answer

A)   chemical erosion
B)   longshore drift
C)   coral
D)   glaciers
E)   coastal plains

Question 11

Stream outflow is important to coastal landscapes because streams provide ________ to the coastal environment.

Accepted Answer

A)   chemically fresh water
B)   sediments
C)   freshwater fish
D)   additions to the volume of seawater
E)   organic material

Question 12

________ is the location of the highest tides in the world.

Accepted Answer

A)   Canada
B)   Tahiti
C)   The People's Republic of China
D)   South Africa
E)   Greece

Question 13

________ is the longest barrier island along the coast of the United States.

Accepted Answer

A)   Santa Catalina Island
B)   Martha's Vineyard, Massachusetts
C)   Mt. Desert Island, Maine
D)   Rhode Island
E)   Padre Island

Question 14

Waves generated by wind are also known as ________.

Accepted Answer

A)   waves of oscillation
B)   waves of translation
C)   trough waves
D)   forced waves
E)   backwash

Question 15

At one time, sea level was higher than it is today.

Accepted Answer

A) True 
 B)False

Question 16

Which of the following is a zone of active deposition of materials by waves?

Accepted Answer

A)   berm
B)   offshore
C)   dunes
D)   foreshore
E)   backshore

Question 17

Many coastal mudflats were once lagoons.

Accepted Answer

A) True 
 B)False  True

Question 18

Which of the following is most important to shoreline erosion?

Accepted Answer

A)   air forced into cracks in rocks
B)   abrasion by water-carried materials
C)   solution of rocks
D)   crystallization of salts in rock crevices and pores
E)   waves

Question 19

Which of the following is NOT associated with beaches?

Accepted Answer

A)   gravel
B)   cobbles
C)   sand
D)   clay
E)   sediment

Question 20

People interfere with the natural flow of sediment in the coastal system. Explain two ways in which this is done.

Accepted Answer

For instance: 1) By nourishing beaches by dumping or pumping sand just up current from the beach so the beach becomes wider and protects the shore better or allows better recreation opportunities. 2) Place groins at right angles to the shoreline. This slows the wave action behind them allowing some additional sand to be deposited. Unfortunately, both of these actions are expensive and do not stop the basic problem of more beach erosion than deposition in some areas.
