Geology Story

The sand began to change over time as the water moved the sand up and down. Once the water came in contact with the grass or dirt, the water began to spill out.

Some of this evidence is supported by experimental labs. This evidence supports that wave erosion changed the surface by water mobilizing the sand.

This evidence supports my theory because wave erosion changes the land by breaking it down.

I infer that Washington’s coastal regions were formed by wave erosion because of what I learned in class about wave erosion. I learned that wave erosion happens more commonly on beaches that are not near oceans. That caused me to think that the coastal regions were formed by wave erosion because they are also on beaches not near large oceans. I believe this is true because the evidence suggests this. Also, when I saw the pictures of it, it reminded me of our lab experiment.

Since the coastal areas are on beaches it has higher chances of suffering from wave erosion. Some people believe that the coastal areas are mostly made out of small rocks, however, they are a combination of both rock and sand.

Many years ago the coastal areas weren’t on beaches because there were not what we envision as beaches back then. The rocks used to be much bigger than they are now.

Once upon a time, the rocks were just a piece of igneous rock that were just big pieces of land and are now just sitting in the water. Weathering broke it off of the land and pushed it in the water. The wave erosion caused the rocks to break off. This may show what the land might have been like before.
