-However the two main factors are Beach Erosion; breaking down of the beaches, sand dunes, and surrounding islands, caused by weather (storms, waves, current, etc.)

-The second main factor is the longshore movement of sand; sand moves underwater not only on and off then coast, but along it

-The longshore current drags sand from one place to another with varying effects.

-Sand continuously moves from one beach to the next. ]]> 2016-12-09 19:31:36 UTC https://padlet.com/wilsonc19/jwjnoksl0zxp/wish/142895839 2.) How the beach line in Florida has changed over the last million years martinr18 https://padlet.com/wilsonc19/jwjnoksl0zxp/wish/142896739 - Over millions of years the beach line has been changed by the rising and falling ocean level.

-The beach line moves in and out as the sea level rises and falls. ]]> 2016-12-09 19:34:35 UTC https://padlet.com/wilsonc19/jwjnoksl0zxp/wish/142896739 3.) How the long shore current effects the coastline martinr18 https://padlet.com/wilsonc19/jwjnoksl0zxp/wish/142896842 - The current moves the barrier islands south by taking the sands from the back and moving it to the front

-The sands from the front of the island can be further pushed off to another barrier island or out into the ocean.  ]]> 2016-12-09 19:34:58 UTC https://padlet.com/wilsonc19/jwjnoksl0zxp/wish/142896842 4.) How dunes are formed martinr18 https://padlet.com/wilsonc19/jwjnoksl0zxp/wish/142896910 - Dunes are directly formed by the constant blowing of wind.

-The wind pushes the sand around

-At some point the sand will begin to catch and build up on things such as rocks, fences, plants, etc.

-This buildup leaves behind large mounds of sand also known as dunes. ]]> 2016-12-09 19:35:09 UTC https://padlet.com/wilsonc19/jwjnoksl0zxp/wish/142896910 5.) The ecological and economic value of dunes martinr18 https://padlet.com/wilsonc19/jwjnoksl0zxp/wish/143226049 - Dunes are used for the protection of property such as houses, resorts, and hotels, from large and threatening waves caused by hurricanes and storms.
- Dunes are also home to animals such as snakes and many different types of birds ]]> 2016-12-12 19:37:29 UTC https://padlet.com/wilsonc19/jwjnoksl0zxp/wish/143226049 6.) Why barrier islands are called barrier Islands martinr18 https://padlet.com/wilsonc19/jwjnoksl0zxp/wish/143464077 -They act as barriers between the ocean and the mainland.

-They protect the mainland from large waves cause by storms.

-The sand from the barrier islands absorbs the impact of the waves.

-It eliminates the need for a sea-wall or some other contraption for preventing storm damage

-Unless you are on the barrier island of course. In which case you will need a great, huge, and beautiful wall.]]> 2016-12-13 19:16:51 UTC https://padlet.com/wilsonc19/jwjnoksl0zxp/wish/143464077 8.) Where the sand on our beaches come from martinr18 https://padlet.com/wilsonc19/jwjnoksl0zxp/wish/143466259 - The sand on our beaches comes from the ocean floors.

- Water currents and waves, affected by storms cause the motion of sand to be pushed from the floor onto the shore creating beaches.

- Much of the sand found on the ocean floors is made up of quartz crystals produced by the weathering of continental land masses like the Appalachian mountains.

- The quartz is washed down America's great rivers into the Atlantic and the Gulf of Mexico where it is carried onto the beaches.]]> 2016-12-13 19:23:34 UTC https://padlet.com/wilsonc19/jwjnoksl0zxp/wish/143466259 7.) The pros and cons of the following ways we control Erosion on beaches Jetties / Groins Sea Walls Beach Renourishment Dune Restoration wilsonc19 https://padlet.com/wilsonc19/jwjnoksl0zxp/wish/143466563 Jetties: pros- stops sand from moving past the jetty

cons- many jetties need to be build so that places past the jetty also get sand. Then after that another jetty is needed etc.

Sea Walls: pros- keeps buildings from having the ground removed from under them due to waves.

cons- the waves bounce of the wall and bring the sand back out into the ocean, so there isn't a beach anymore.

Beach Nourishment: pros- you get to have a beach

cons- it is temporary because plants cannot grow so the sand just gets washed into the ocean.

Dune Restoration: pros- sustainable, healthy for ecosystem,  looks best.

cons- what cons?]]> 2016-12-13 19:24:27 UTC https://padlet.com/wilsonc19/jwjnoksl0zxp/wish/143466563 9.) Adaptations that specific plants have in order to live in the dunes. martinr18 https://padlet.com/wilsonc19/jwjnoksl0zxp/wish/143471503 - Their are five major factors that limit the life on dunes and therefore, plants must have specific adaptations to be able to survive them.

1. Wind is constantly shifting sand around the roots, making it harder to maintain a foothold

2. Continuous bombardment by wind-blown sand abrades plants tissues and threatens to bury the plant

3. Rain drains away quickly through the course, porous sand, but plants growing in sand need freshwater often

4. Offshore winds blow salt spray onto the dunes; then, when rains follow, the salt is washed away. Plants have to cope with both extremes

5. Coastal sands are exposed to extremes of temperature, with summer midday readings commonly above 100 degrees fahrenheit.

Some adaptations are:
-two-stage fruit(coastal Searocket)
-underground fruit(Beach peanut)
-longer/taller roots(sea oats)

Why barrier islands are important to migratory butterflies martinr18 https://padlet.com/wilsonc19/jwjnoksl0zxp/wish/143511124 -Barrier islands are important to migratory butterflies because they are a destination for many butterflies flying south.

-Barrier islands are also home to the milkweed plant, milkweed is necessary for the survival of many butterflies, especially the Monarch.

-Milkweed helps the butterfly in its transformation into adulthood and is also what causes these butterflied to be poisonous and bad tasting. ]]> 2016-12-14 01:31:12 UTC https://padlet.com/wilsonc19/jwjnoksl0zxp/wish/143511124 Sources martinr18 https://padlet.com/wilsonc19/jwjnoksl0zxp/wish/143703463 1.)
