Question 1

Many coastal mudflats were once lagoons.

Accepted Answer

A) True 
 B)False  True

Question 2

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 3

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.
