Features of Submergent Coastlines
1. Estuaries
2. Embayments
3. Barrier Islands
4. Spits
Features of Emergent Coastlines
1. Sea arches
2. Sea stacks
3. Wave-cut terraces
4. Sea Cliffs
Baymouth Bar
Narrow ridge of sand taht stretches completely across the mouth of a bay
Spits
Narrow Strip of land that juts into the sea
Tombolo
long, thin sandy connection between the island and the shore
Long Shore current
Produced within the surf zone that flow parallel to the shore and transport more sediment than beach drift
Beach Drift
The uprush and backwash of water from each breaking wave moves the sediment in a zigzag pattern along the beach
Factors that Govern the Size of Waves
1. Wind velocity
2. Wind duration(Length of time the wind has blown)
3. Fetch (Distance wind has traveled across open water)
Wave Base
Depth to which water is affected by wind
Wave length
Vibration transmitted from particle to particle through a body or elastic meduim, as in the transmission of sound
Wave Height
Measurement of trough to the Crest
Trough
Lowest point in a wave
Crest
Highest point in a wave
NADW(NORTH ATLANTIC DEEP WATER)
Flow South, are cold dense enough to be the deepest waters in the very northern Atlantic
Distributes heat throughout oceans
AABW(ANTARTIC BOTTOM WATER)
Flows North, Forms immediately adjacent to the Antartic continent during the winter freeze which extracts freshwater out of the ocean as ice and leaves behind very cold salty brine that is the densest water in the Atlantic Ocean
Thermohaline Circulation
Internal circulation of the oceans driven by Gravity acting upon density differences(Caused by temperature and Salinity) in the water
Peruvian Current(Humboldt Current)
Cold Ocean Current, that flows northward off the coast of South America
Currents that make up the North Atlantic Gyre
1. North Pacific
2. South Pacific
3. North Atlantic
4. South Atlantic
5. Indian Ocean
Neap tides
Lowest daily tidal range occurs during the first and third quarters of the moon
Spring tides
Highest daily tidal range occurs during a full moon and a new moon
Tides
Daily changes in the elevation of the ocean surface
Emergent Coasts
Develop either becasue an area experiences uplift or as a result of a drop in sea level
Submergent Coasts
are created when sea level rises or the land adjacent to the sea subsides
Groin
barrier built at a right angle to the beach to trap sand that is moving parallel to the shore
Sea Walls
designed to armor the coast and defend property from the force of breaking waves
Wave Refraction
Bending of waves
Abrasion
sawing and grinding action of the water armed with rock fragments
Coriolis effect
Earth's rotation, currents are deflected to the right in the Northern Hemisphere and to the left in the Southern hemisphere
Gyres
Large whirls of water within an ocean basin
Ocean Currents
masses of ocean water that flow from one place to another
