Which one of the following coastlines would typically have bedrock features such as wave-cut cliffs, sea stacks, sea arches, and wave-cut platforms?

________ are constructed perpendicular to the shoreline and designed to interrupt beach drift and longshore currents that "change" shorelines irrespective of human plans and foreshore engineering works.

Low initial costs and low maintenance costs, low potential for storm damages, and low negative environmental impact are consequences of policies to ________.

Name two intentional interventions that can reduce beach erosion.

Waves are forms of ________ that move through the water, not the water itself.

What is the landward limit of the shoreface zone?

Which one of the following would not be a likely effect of a breakwater?

Examine the words and/or phrases for each question below and determine the relationship among the majority of words/phrases. -Choose the option that does not fit the pattern.

What term denotes a sand bar built across the former mouth of an estuary and separating it from the open sea?

A(n)________ current forms during an incoming or rising tide.

Along a newly established coastline with varied geology, waves may at first increase the irregularity by selectively eroding the unconsolidated deposits and weaker rocks.

________ are structures built perpendicular to the coast along the entrance to navigable tidal inlets, river mouths, or harbours, to stop them from shifting location or filling with sand from beach drift or longshore currents.

What two terms denote the complex, turbulent, shallow water and sand movements associated with a wave breaking in the foreshore zone?

In large bodies of water like the oceans or very large lakes, where is abrasion most intense and why?

Tidal flats are mostly submerged under ebb currents.

What near-shore, shallow-water environment is characterized by finely laminated, organic-rich muds with minor interbedded fine sands?

________ directly generates the major surface currents in the world's oceans.

A ________ extends partway across the mouth of a bay or estuary.
