^this is my essay on how Boston's Harbor Islands formed.


 * __ Creation of Boston Harbor Islands __**

Hi, my name is Ranger Greene and I am here to tell you about the Boston harbor Islands. The Boston harbor islands are a group of small islands. These 34 islands were formed when __glaciers__ melted, many many many years ago. These glaciers left behind rocks and mounds of __till__, which after being eroded, a little formed __drumlins.__ As the glaciers continued to melt, it caused the sea level to rise and rise and rise. Soon enough, the drumlins were isolated from each other by water and turned into __drowned drumlins__. If you compare how the islands looked last week to how they look today, the may not look too different. But over thousands and thousands of years, different types of erosion occur. One of these ways is __erosion by waves__. __Beaches__ are usually the most affected by waves. When waves hit the rock of the islands, they hit it consecutively with such a force the some of the rocks cracked by __impact__. Waves also picked up sand and gravel that hit the shore and wore it away in a process called __abrasion.__ That same sand contributed to __deposition__ when it piled up on the shore after being dropped by the waves. Another factor that helped create the shores of our islands is __long shore drift.__ Long shore drift is when angled waves create a current that carries sand dropped in deposition down the shore and formed __spits__, long parts that stick out from the shore, like Cape Cod. Even __wind erosion__ affected the islands shape when it blew the __loess__ around. Last but not least, __erosion by rain__ heavily affected the Boston Harbor Islands. __Runoff__, the left over rain that wasn’t sucked up by the earth, runs over the surface of the earth and forms holes or grooves called __rills__ and __gullies__ in the surface, which caused hills and uneven land on many of the islands. That’s all for me folks, hope you learned a lot about erosion on our very own Boston Harbor Islands!

During my field trip to George's island, I learned a few new and interesting things. One thing I learned alot more about during the field trip were drumlins. At first, I thought they were just oddly shaped islands. But as soon as i got to the island and saw the cliff at one end of the island with my own eyes, I realized it had been dropped there by a glacier and eroded by many components. I also learned and saw alot of how the earth was changed by erosion. One example is the island itself. At first, the island was much larger and higher. But as more and more glaciers melted and the water level rose, the island started to get consumed by the ocean and shrunk in overall size. Storms also effected the height of the cliff at one end of the island.
