Feeder Bluff

My claim on checkpoint one was, ¨Geological processes change Earth’s surface over time by moving rocks, sand, etc to different parts of the earth and soon enough there is so much it changes the shape of what it landed on¨. Also another way is when the water levels rise and the grab bit of the rock away and sometimes that rock turns into a wall.  The evidence that supports this claim is right here, ¨At wave actions when the sandy water was being pushed to the little pile of sand the pile eventually got bigger and bigger because there was sand in the water. Another one is when we were at the Deposition station, when the water was poured in the little river turned into 3 rivers that started at the same place but ended up on different parts of the sand¨.

Inference, I think Feeder Bluff formed from wave erosion which is the water hitting it and taking bits and bits of it away so many times and eventually it turned into a wall of dirt and other things like that.

Evidence, I think that wave erosion happened and that there where high tides before because you can see the sand is wet in the picture. Also this is an example of one of our stations from our lab station. There was a bucket and some sand and when you splashed water against the sand it started to go into the water and the hill got smaller. According to http://www.coastalwatershedinstitute.org/blog/?p=169, “sea levels rose and glaciers receded from the Olympic Peninsula, leaving behind a 100-300 foot thick legacy of highly erodible nearshore and beach building clay, sand, gravel and cobble deposits”. So this is why I think wave erosion is what created feeder bluff.

This Is A Real Picture Of Feeder Bluff.

In this picture it show what feeder bluff looks like right now. The height is about 75 feet and length from the water to the cliff is about 20 feet.

In this picture it shows what Feeder Bluff will look like in about 50 years. The height is about 50 feet and the length from the water to the cliff is about 30 feet.

In this picture it shows what Feeder Bluff will look like in about 100 years. The height is about 50 feet and the length from the water to the cliff is about 40 feet.

In this picture it shows what Feeder Bluff will look like in about 150 years. The height is about 25 feet and the length from the water to the cliff is about 50 feet.
