[image]

Definition
a ring-shaped coral reef or a string of closely spaced small coral islands, enclosing or nearly enclosing a shallow lagoon
Term

Backwash

[image]

Definition
water thrown backward by the force of motion
Term

Barrier Island

[image]

Definition
A broadened barrier beach, habitable in places, that provides a measure of protection for the mainland, as during hurricanes and tidal waves.
Term

Barrier Reef

[image]

Definition
a reef of coral running roughly parallel to the shore and separated from it by a wide, deep lagoon.
Term

Beach

[image]

Definition
the part of the shore of an ocean, sea, large river, lake, etc., washed by the tide or waves.
Term

Blowouts

[image]

[image]

Definition
A sudden escape of a confined gas or liquid
Term

Corals

[image]

Definition
A rocklike deposit consisting of the calcareous skeletons secreted by various anthozoans. Coral deposits often accumulate to form reefs or islands in warm seas
Term

Deflation

[image]

Definition
the erosion of sand, soil, etc., by the action of the wind.
Term

Desert Pavement

[image]

Definition
is a desert surface that is covered with closely packed, interlocking angular or rounded rock fragments of pebble and cobble size.
Term

Dust Storm

[image]

Definition
a storm of strong winds and dust-filled air over an extensive area during a period of drought over normally arable land.
Term

Fetch

[image]

Definition
an area where ocean waves are being generated by the wind.
Term

Fiord

[image]

Definition
A long, narrow, deep inlet of the sea between steep slopes.
Term

Fringing Reef

[image]

Definition

a coral reef close to and along the land.

Term

Lagoon

[image]

Definition
any small, pondlike body of water, esp. one connected with a larger body of water.
Term

Loess

[image]

Definition
a loamy deposit formed by wind, usually yellowish and calcareous, common in the Mississippi Valley and in Europe and Asia.
Term

Longshore Current

[image]

Definition
currents of water flowing parallel to the shore. Longshore currents are formed by waves striking the shore at an oblique angle.
Term

Period

[image]

Definition
the basic unit of geologic time, during which a standard rock system is formed: comprising two or more epochs and included with other periods in an era.
Term

Refraction

[image]

Definition
the change in direction of a propagating wave (light or sound) when passing from one medium to another
Term

Rip Current

[image]

Definition
A strong, narrow surface current that flows rapidly away from the shore, returning the water carried landward by waves. Also called rip tide, tiderip.
Term

Sandbar Wave Height

[image]

Definition
A ridge of sand deposited by waves as they slow down near shore by the horizontal distance between two wave crests.
Term

Sea Cliff

[image]

Definition
is a significant vertical, or near vertical, rock exposure. Sea cliffs are formed as erosion landforms due to the processes of erosion and weathering.
Term

Swash

[image]

Definition
the surging or dashing, sometimes violent, of water, waves, etc.
Term

Tsunami

[image]

Definition
an unusually large sea wave produced by a seaquake or undersea volcanic eruption.
Term

Ventifact

[image]

Definition
a pebble or cobble that has been faceted, grooved, and polished by the erosive action of wind-driven sand.
Term

Wavelength

[image]

Definition
the distance, measured in the direction of propagation of a wave, between two successive points in the wave that are characterized by the same phase of oscillation.
