Question 0

Currents are essentially agents of

Answer 0

Deposition and transportation

Question 1

Waves generated by winds are essentially agents of

Answer 1

Erosion

Question 2

The most notable landforms produced by waves are

Answer 2

Rocky cliffs and head lands

Question 3

Most common landforms produced by currents are “deposition all features”:

Answer 3

Beaches and sad bars

Question 4

beaches are built up in “” and eroded in “”

Answer 4

Normal weather

Storms

Question 5

Erosion and deposition are part of “” the distinctiveness of coastal Milieu involve the transfer “interphase” of energy from the atmosphere(air) to the hydrosphere(ocean) to the lithosphere.(land) large water=larger effects of coastal processes.

Answer 5

Coastal processes

Question 6

Waves and wind

Answer 6

Geomorphic agents

Question 7

Most important great influence in coastal lines. Generates waves. Topography of large body of water can be deformed abruptly by this. A deformation creating waves and ocean currents shapes coastlines.

Answer 7

Wind

Question 8

Causes erosion

A disturbance on water caused by energy passing through it.

Answer 8

Wave

Question 9

Energy and mass move differently. Moves back and forth over the same space again and again. Gentle phenomenon.

Answer 9

Wave of oscillation

Question 10

Same horizontal direction, power force of destruction.

Answer 10

Translation

Question 11

Long shore currents. Tides and tidal currents. Volcanic eruptions. Tidal(storm) surges. Long term (tectonic/climate)effects on sea level change. Reef building corals. Sea ice. Glaciers.

Answer 11

Other agents

Question 12

Hydraulic pounding
Chemical action
Sea cliff erosion

Answer 12

Wave erosion

Question 13

Small waves/large storm waves, spray from breaking waves,debris, air, hurling water, much coastal erosion by eave rock particles. More abrasive

Answer 13

Hydraulic pounding

Question 14

Most rocks soluble in sea water. Salts from seawater crystallize in crevices and pores of onshore rocks/cliffs. This deposition mechanism makes rocks weaker and breaks them up with salt wedging

Answer 14

Chemical action

Question 15

Most effective erosion / at or slightly above sea level, notches cut off on base of cliffs.

Answer 15

Des cliff erosion.

Question 16

A seismic sea wave -retreating :pulling back. Triggered by disruption on sea floor.

Answer 16

Tsunami

Question 17

Irregular rise. Result from gravitational influence of sun/moon topographic effects are small. Only significant in narrow bays. Shallow seas.

Answer 17

Tides

Question 18

Motion of wave in which the individual particles of the medium (such as water) make a circular orbit as the wave form passes through.

Answer 18

Wave of oscillation

Question 19

The horizontal motion produced when a wave reaches shallow water and finally “breaks” on the shore

Answer 19

Wave of translation

Question 20

Phenomenon whereby waves change their directional trend as they approach a shoreline, results in ocean waves generally breaking parallel w/the shoreline.

Answer 20

Wave of refraction

Question 21

Long sinuous ridge of stratified glacial drift composed largely of glacial fluvial gravel and formed by the chocking of subglacial streams during a time of glacial stagnation.

Answer 21

Esker

Question 22

Change in sea level due to an increases or decrease I’m the amount of water in the world ocean.

Answer 22

Eustatic sea level change/eustacy/eustatic force.

Question 23

A linear deposit of marine sediment that is attached to the land at one or both sides

Answer 23

Spit

Question 24

A spit formed by sand deposition that connects an island to the mainland. Less common but more distinctive, deposited feature. Connects near shore island w/mainland.

Answer 24

Tombolo

Question 25

A body of quiet salt or brackish water in an area between a barrier island or a barrier reef and the mainland. Extensive barrier island isolates the water between itself and the mainland, and forms a body of quiet salt of brackish water.

Answer 25

Lagoon

Question 26

Long narrow "sand bar " built up on shallow offshore waters oriented parallel to the shore. island composed of sediment generally oriented parallel to the shore

Answer 26

Barrier island

Question 27

Caused by tectonic uplift or sinking of land masses. Eustatic increase or decrease in volumes of water in ocean. (Pleistocene glaciations) thermal expansion. Glacial melting. Consequences>> sea level rise up to .5m (20"). Retreat of shorelines up to 3m. 100ft

Answer 27

Change in sea level and lake level.

Question 28

Annual freezing of sea ice causes near shore ice to push against the land causing minor erosion and deforming the shoreline, "like small glacial advance"mostly in the Antarctic and arctic regions

Answer 28

Ice push

Question 29

Aquatic animals= Calcium carbonate secretions. Reef-building organism that's most important. skeleton of calcium carbonate "coral polyps"

Answer 29

Organic secretions

Question 30

Source of sediment for beaches sand and sediment deposited mover around by coastal waters, I'd disrupted outflow, beaches along coastal lines may shrink

Answer 30

Stream outflow

Question 31

Water moves parallel to the shoreline. Transporters of sediment "Along the shore"

Answer 31

Longshore currents

Question 32

Linear strand of marine sediment attached to shore formation extends out to open water in a down current direction and usually involves longshore current transport and

Answer 32

Spit

Question 33

Spit becomes extended clear across the mouth of a bay to connect w/land on the other side, and transforming the bay into a lagoon.

Answer 33

Bay mouth bars
