Clays and silt usually do not exist on ocean ______.

A dune formed of sand is known as a sand ______

Generally, the larger the sand particles the steeper the beach ______.

A nearly horizontal portion of a beach with an abrupt face, formed from the deposition of material by wave action at high tide is called a ______

Barrier Island: These are important part of the physical system in some areas. They are long narrow island or spits laying parallel to the ______.

The ridge marking the seaward limit of the berm is known as the berm ______

A sand ridge or ridges, running parallel to the shoreline and extending along the shore outside the trough is called a longshore ______

Boston Science Museum Wave Flume Beach Sediment ranges from fine sand to ______.

Tombolo is a deposition landform in which an island is attached to the mainland by a narrow piece of land such as a ______ or bar.

The average height of the low water over a 19-year period is referred to as Mean Low ______

The line that forms the boundary between the land and water, especially the water of a sea or ocean is known as the ______

Lagoons provide a habitat for a wide variety of wildlife and many lagoons serve as safe harbors and navigation ______ ways.

The beach constantly adjusts its profile to provide the most efficient means of dissipating incoming wave energy.Although an equilibrium is sometimes reached between beach and the sea, the “peace” is short-lived and the “battle” soon begins anew. This is known as dynamic beach response to _____

In storm conditions, the coast must respond with extraordinary measures such as sacrificing large sections of beach and dune. In time, the beach may recover but often not without permanent loss. This is part of the dynamic beach response to ______ conditions.

Following a storm, there is a return to more normal conditions which are dominated by low long swells. The wave transports sand from the offshore bar built during the storm and places the material on the beach. This is a part of beach and dune recovery from storm ______.

Wind then transports the sand onto the dunes where it is trapped by the vegetation. In this manner, the beach begins to recover from the storm ______.

The rebuilding process takes longer than the short span of erosion during the storm event. Sometimes full recovery of the beach never occurs because the sand is deposited too far offshore during the storm to be returned to the beach by normal wave ______.

There are two general types of dynamic beach response to wave motion: Response to normal conditions and response to storm conditions. In storm conditions, the coast must respond with extraordinary measures such as sacrificing large sections of beach and dune. This is known as dynamic beach response to ______.
