The picture from 1/20 shows a little white/snowy/ or icy tone of colors along the shoreline. Will it be ices? snows? It melts? Therefore, the picture from 1/25 does not have it and shows only water? Or it shows different times of tides ( phases of tide)?

# data[].attributes.body
I think it is about two phases of tide.. ebbs and flows

# data[].attributes.body
I wonder where these pictures were taken? I also wonder what is causing the land to diminish from 1/20/21 to 1/25/21

# data[].attributes.body
I know that during different times of the year the land on the earth experiences change

# data[].attributes.body
I think these two photos shows the tides.

# data[].attributes.body
I wonder why they chose to show two pictures showing the same area 5 days apart. Tides can change in one day so what is the purpose of showing 2 different dates, 5 days apart?

# data[].attributes.body
I know that the photographs are showing what appears to be the landscape of sandy area or beach and its differences over the course of five days.

# data[].attributes.body
I wonder what caused such changes in the land over a five day period.

# data[].attributes.body
I know that waves break when they hit the shoreline. I know that the pictures show how the water level and roughness of the water changed in 5 days.

# data[].attributes.body
I wonder why the water changed so much in five days. Why was it rough in the first photograph and calm in the second photograph? Were these pictures taken during the same time of the day?

The activity allowed me to see how the earth and water interact when they come into contact with each other.  As the waves move they cause the earth/sand to move

The video simulation showed me that water can cause cause a significant change in the earth. As the water pushed against the earth's surface the rock began to erode

By viewing the Coastal Erosion Video, I learned that force of waves can cause change to earth's surface or land.

From viewing the Wave Forces demonstration video, I gathered that when the waves hit the shoreline, sand moves further toward the water, causing the slope of the sand to decrease.

The Costal Erosion video shows that the coastline has changed due to the action of waves- cliff on the sandy shoreline falls and rocky side of coastline has disappeared.

With the videos I watched, I have observed how the collision of the waves and the sand/land causes erosion.

# data[].attributes.body
From watching the videos, I observed how natural elements, such as water have the power to change and shape the land through a process known as erosion.

I learned that storm tides are caused by the gravitational pull of the sun and moon and have the greatest effect during a new or full moon.

# data[].attributes.body
I learned that a storm surge can cause an abnormal rise in the seawater level during a storm.

# data[].attributes.body
I learned that tides are created because the strength and direction of the gravitational pull varies depending on where on Earth you are. This variation creates the differential forces or tidal forces that in turn cause tides.

# data[].attributes.body
I learned that storm tide is the total observed seawater level during a storm. It is a combination of a storm surge and normal high tide.

# data[].attributes.body
From watching the videos, I have learned through observations how the waves can change the land and cause erosion.

# data[].attributes.body
I have learned from the videos that air and water are two very powerful sources that can cause major changes to landmass.
