Shoreline Features
100

Masses of ocean water that flow from one place to another

Surface Current

100

Ocean tides result from gravitational forces caused mainly by this

What is the moon?

100

The source from which most ocean waves obtain their energy and motion

What is the wind?

100

The name given to the accumulation of sediment found along the shore of a lake or ocean

What is a beach?

100
Shoreline features that originate primarily from the work of waves
erosional features
200

What is a gyre?

large circular moving current systems within an ocean basin

200
The moon and its gravitational pull towards the earth causes what?
Tides
200
The distance from crest to crest or trough to trough is called what?
Wave length
200
Currents that flow parallel to the shore and move large amounts of sediment along the shore
Longshore Current
200
Type of erosional feature
wave-cut cliffs, platforms, sea arches, sea stacks
300

The deflection of currents away from their original course as a result of the earth's rotation

coriolis effect

300
What is a Neap Tide?
the sun and moon partially offset the influence of the other and the daily tidal range is less
300
The highest point of a wave is called what?
The crest
300
What is wave refraction?
The bending of waves
300
Spits, bars, and tom bolos is a type of what?
Depositional feature
400

The movement of cold water from deeper layers to replace warmer surface water and replace nutrients

Upwelling

400
The difference in height between successive high and low tides is?
Tidal Range
400
Name one factor that a wave depends on
wind speed, length of time wind has blown, fetch
400
When is there the most force against the shoreline?
During a storm
400
Narrow sandbars parallel to, but separated from, the coast
Barrier Islands
500

In what latitude (high or low) does surface water become cold, so its salinity increases as sea ice forms

High

500
What is a mixed tide
Each high and low tide, each day, are all at different heights
500

the distance that the wave has traveled across open water

fetch

500
wave energy is concentrated agains the sides and ends of headlands that project into the water because of what?
Wave refraction
500
A groin or breakwater is a type of what?
Protective structure for the shore
600

a global system of surface and deep ocean currents driven by temperature and salinity-driven density differences

What is the Oceans Conveyor Belt?

600

Single high tide and low tide each day

What is a Diurnal Tide

600
What is wave period
The time it takes one full wave, on wave length, to pass a fixed position
600
The sawing and grinding action of rock fragments in water
abrasion
600

A ridge of sand that connects an island to the mainland or to another island

What is Tombolo?
