I am wondering if a Hurricane passed through this area.

# data[].attributes.body
I know the landscape changed which is evidence of physical weathering and erosion.

# data[].attributes.body
It looks like some sort of erosion or possibly has something to do with global warming.

# data[].attributes.body
I was wondering why there is such a difference in the color of the water in such a short period of time?

# data[].attributes.body
I know that the landscape and the water color changed over 5 days which is evidence of some sort of erosion

# data[].attributes.body
I am wondering what happened in a 5 day period to make the water color and the landscape change so dramatically... was it flooding caused by a hurricane?

# data[].attributes.body
Based on the dates of the photos, it appears as if erosion has taken place because there is less land and more water in the second photograph.  It also looks like the color of the water has changed as well in the second photograph.

# data[].attributes.body
Was there a tropical storm or hurricane? Was there heavy rain or another type of weather related event that could have caused the erosion? Was it high tide? Were the photographs which were taken on different days taken at the same time?

# data[].attributes.body
Weathering and erosion slowly moves sediment and creates changes to landforms over time.

Why does the strip of beach coast remain relatively unaffected?

What are the human impacts?

What was the cause?

When I looked at these pictures I noticed more water and less land in the second picture. It also looked like the water was darker blue. I think the tide was at a higher level in the second picture.

At first I thought it was just showing tide changes, but after seeing the other posts, I wonder if a natural disaster affected the water level such as a hurricane or severe rainstorm. I also wonder now what time those photos were taken.

I know the landscape has changed. I could be some sort of erosion or deposition. There is more water in the second picture than in the first.

# data[].attributes.body
What caused this land to change so drastically in just five days?

# data[].attributes.body
I know the water level is higher over the landscape in the later picture #2 than pic #1, which may be due to some possible weather changes.

# data[].attributes.body
What made the changes to the landscape in a 5 day period?

What led to the initial changes to whatever led to the change in the landscape?

# data[].attributes.body
Since I'm noticing the picture are only 5 days apart, I am thinking a storm and/or flooding.

# data[].attributes.body
I am wondering what damage this has done to the landscape. Or what it means for continuous flooding/rain fall.

# data[].attributes.body
It seems that the water in the first picture is clearer and not as murky in the second photo, also the sand itself seems to have eroded more in the second picture. Maybe the difference is low and high ide.

# data[].attributes.body
I am wondering if there was a hurricane where all the silt was brought up from the bottom of the sea floor.

# data[].attributes.body
-I know more sand shows in the top photo.
-I know the water level is higher in the bottom photo.
-I know the water color is different
-the photographer's name is clearer in the second photo
-I know that photo was taken five days apart

# data[].attributes.body
-I wonder what time of day were both pictures taken
-I wonder if the photographer used the same camera to take the photos.
- I wonder if the position of the sun had an affect of the colors and objects in each photo.
- I wonder if it was high tide in one photo and low tide in the other.
-I wonder why the water looks more bluish green in the later image and there seems to be plants or some kind of vegetation in the later photo as well.

It looks like the landscape has been eroded away. It also could be high tide.

# data[].attributes.body
Could this be a combination of high tide and erosion?

# data[].attributes.body
I know that the landscape changed over 5 days only due to physical weathering and erosion.

# data[].attributes.body
What caused that change in the landscape in just 5 days?

# data[].attributes.body
When comparing the photographs, I see that over five days water rose over a large portion of the land. The water also covered some of the sand.

# data[].attributes.body
I wonder if a natural process such as high tide and low tide changed the level of the water. I also wonder why the water in the bottom photograph appears bluer.

# data[].attributes.body
I noticed there is more water in the second picture than the first image. Also, this change happened in just 5 days. It seems to be an erosion or some type of weather change.

# data[].attributes.body
I wonder what caused this landscape to change just in 5 days. Was there a combination of things or events?

# data[].attributes.body
I know that erosion can take place over time. I can see from the photos that the landscape has changed and there is less of the shoreline in the second photo.

# data[].attributes.body
I noticed that the span of days was not that long. I wonder what the pictures will look like in another 5-10 days?What is happening that is causing such a rapid erosion? Is there any way to slow down the erosion process?

# data[].attributes.body
I know that water levels can change for many reasons. Sometimes it is part of a daily tidal pattern. Over longer periods of time, it can be caused by global warming. These photos were taken 5 days apart, so it seems like a short timeframe for changes due to global warming. However, erosion also happens quickly on sand & soil.

# data[].attributes.body
Is ice and cold involved in this change in landscape?

Is this something that happens regularly or is it a one time occurrence?

# data[].attributes.body
I know that a coastline can show high tide and low tide twice each day (two high tides and two low tides in a 24 hour period). I also know that when water moves it can move small pieces of the land which can eventually change the shape of a coastline.

# data[].attributes.body
I wonder if both photos were taken at the same time of day.

# data[].attributes.body
Erosion can happen over time through the work of water or in a short period of time if there is a large event

# data[].attributes.body
Is this an example of the natural impact of water eroding the sand? Or is this a manmade change? Or is this a result of human impact on the enviroment?

# data[].attributes.body
Does this occur often or is this change seasonally ?
Is this the affects of a storm or rainy season?

# data[].attributes.body
May be the cause of global warming, causing the ice sheets to melt , sea levels to rise . erosion or weathering . Thermal expansion : the warming of the ocean .

Waves hitting the sand and rocks are causing erosion.  The landscape is changing due to the water breaking down the rocks.
Adrienne Pappalardo

# data[].attributes.body
Water has the ability to change land formations and rocks

# data[].attributes.body
The weather patterns and the water constantly brushing up against the shore caused erosion where the landscape changed.

# data[].attributes.body
After completing the four stations and watching the ocean model video, I learned more about the affect of the waves on sand movement. When one force is stronger than the other, the results would be imbalanced and thus what caused the sand to move.

# data[].attributes.body
objects such as rocks or vegetation can act as a barrier and slow down erosion and flooding.

# data[].attributes.body
After watching all of the videos I learned how marine currents play a significant role on how much erosion will occur

# data[].attributes.body
Plant roots and rocks stop water from eroding land too quickly.

Water changes the shape of land over time with the help of the force of water.

I observed in the mangrove video that vegetation slows down erosion. Eventually, after a certain amount of water has flowed onto the land, some flooding occurs.

STORM SURGE is an abnormal rise of water caused by the wind energy from a storm pushing the water toward shore. If this is combined with the regular high tide, this is considered a STORM TIDE and can be even higher and cause even more damage.

"A second type of sand comes from living things, such as corals and clams. After the animal dies, the ocean slowly wears down its skeleton or shell into tiny particles. This type of sand is common on tropical beaches."

That is why we need to leave seashells and clams on the sand because they will be broken down into sand =)

# data[].attributes.body
Sand dunes provide natural coastal protection against storm surge and high waves, preventing or reducing coastal flooding and structural damage, as well as providing important ecological habitat. They also act as sand storage areas, supplying sand to eroded beaches.

# data[].attributes.body
I am still wondering how this occurred over the course of 5 days. In my head i'm thinking of rock but it could just be sediment that has just eroded away in a matter of hours.

The third and least common type of sand is formed from the minerals that are dissolved in water and that dried up water with those minerals leaves sand like crystals, which forms sand.

Tides move in and out around twice a day, but not exactly. The time it takes Earth to reach the same position in relation to the Moon is, on average, 24 hours and 50 minutes, known as a lunar day. Because the tidal force of the Moon is more than twice as strong as the Sun's, the tides follow the lunar day, not the solar day.

# data[].attributes.body
Tides are created because the strength and direction of the gravitational pull varies depending on where on Earth you are. The tidal forces of the Moon are much stronger than the Sun's because it is so much closer to our planet, causing a much greater variation in the gravitational force from one location to another. The Sun's gravitational force, on the other hand, varies much less because the Sun is so far away.

There are different types of sand. I learned that animal skeletons break down on tropical beaches.
I also learned that surges are caused by a storm's winds pushing water onshore, which reminds me of the song in the book, "Wind and Water shape the land".

Erosion changes the landscape of an area. Erosion happens over a period of time and it does not have to happen in years. It can happen in a much shorter time frame.

# data[].attributes.body
Water frequency is another factor in how fast the erosion will take place.

# data[].attributes.body
How much faster does salt water effect the erosion process as opposed to fresh water? Will the land, rocks be eaten away faster and at what rate?

# data[].attributes.body
I learned that tides are reliable. They move in and around twice a day.

I also learned that storm surges can erode beaches and coastal highways as well as affect rivers and lakes as it moves inland. Furious winds drive deadly water flows of water from sea to shore.

# data[].attributes.body
Storms that happen during full moons tend to have larger tidal surges

# data[].attributes.body
Did a storm during a full moon cause such a big tidal shift?

If it was a storm surge that occurred how did it affect the sea floor? How long will it take for the water to recede? will the water recede?
