Erosion on the beach
This is a sand fence on Nantucket Island Mass. What does this fence tell you about wind erosion and the dunes? Why do you think there is more sand on one side of the fence? Why do you think the fence was put there? Feel free to do some web research to help answer these questions. Also post any additional questions that this picture brings to you.

The fence tells me that wind erosion makes bigger dunes. I think there is more sand on one side because wind erosion builds up the dunes and the fence prevents the dunes from going past it. I think the fence was put there to make sure wind erosion does not effect what is on the other side of the fence.
Maybe They have the fence do people don't step on the Plants.
there is more sand on the side closer to the ocean the fence is there to stop more erosion.
The fence makes the erosion make bigger dunes.
I think that the sand is higher because the sand builds up, and that they put there fence there to stop more erosion
and wind moves the sand and creates dunes
I think the sand got higher and they put the fence there to block more erosion.
The fence makes the erosion make bigger dunes.
I believe that the fence is there to stop more erosion then is happening. Also the fence is there so it prevents the dunes from going past it. There is also more sand on one side because the sand makes dunes.
I think its put there to stop some erosion.I think sand is higher on one side because one side is closer to the ocean and the ocean has lots o' sand because o' beaches.
The fence is by all of the sediments blowing on the fence from the wind. Because all of the sand is being blown from one side to another. So it will stop more erosion.
it is owen
This picture tells me that dunes take a long time to form and that wind picks up the sand of the beach easily. The reason that there is more sand on one side of the fence is that when people walk by the sand builds up against the fence, and that the wind blew it there. I think the fence is there to act as a windbreak.
The fence tells me that the wind makes bigger dunes.
I think there is more sand on one side because the fence keeps the sand on one side.
I think the fence is there to block off property
Wind erosion makes bigger dunes, There is more sand on one side because wind erosion builds up the dunes and the fence prevents the dunes from going past it, the fence was probably put there so wind erosion does not effect what is on the other side of the fence
the fence acts as a wind break and stops abrasion
The fence acts as a wind brake. It drops sediment forming a dune. The grasses are endangered and they hold the dunes together.
The winds move the sand and the fence gets buried in the sand.
The wind does stuff to the sand which does other stuff to the fence and a bunch of stuff happens.
they drag things down

This shows you that the wind, blew a lot of sand segments up against the fence so there was blockage.
I think that the fence acts as a wind breaker. I also think that there is more sand on one side than the other because the wind probably blows in one direction a lot.
Wind erosion makes bigger dunes, there is more sand on one side because wind erosion doesn't make it even. The fence prevents sand by going by, so that the grass can grow? I don't know

The fence tells you that wind and erosion makes bigger dunes. I think the fences are there because it keeps the wind from bringing more sand on the beach and making more dunes.
I think that the fence acts as a wind breaker. I also think that the reasons there's more sand on one side than the other is because of wind.
I also think the fence was put there to allow sand to build up in the direction where the wind is blowing, but no where else.
to show the way it makes the dunes

The fence is side ways because of erosional forces.

the fence makes the erosione and dunes littler so its not so bad
the wind and the sand took it down over the years
The wind is pushing the dune into the fence therefore causing the fence to tip over.
NOAH L I think that the fence is there because to stop sand build up

Wind erosion makes bigger dunes, there is more sand on one side because wind erosion doesn't make it even. The fence prevents sand by going past that point
The fence tells me that wind erosion can transport sand and deposit next to places such as the fence therefore knocking the fence in a certain way so dunes may be able to form. The fence was probably put there in order to reduce wind erosion.
its a beach and thats sea grass for high tides. that fence is to keep back people from the fence
The wind did that to the fence and all that sand pushed up against it.
The fence shows that the wind is powerful enough to blow sand and particles of the dunes against the fence.

i copyed form Natanya! :D
it shows how a fence can stop wind from pushing sand through it by breaking the wind
It tells me that wind makes the sand blows on to the other side.
wind and to be nice looking !
I think the fence tells me that the wind can blow in different ways to build sand dunes I think the there is more sand on the other side because the wind pushes it over and I think the fence was put there so there won't be as much sand flying around.

The wind is very strong. The wind pushed all the sand to one side of the fences.
Wind is a strong force. The wind pushes the sand.
