MY SONG

Lyrics to my Song

**__My Reflection__** I learned a lot from the trip to George’s Island. First, a glacier formed the Boston Harbor Islands. The glacier created drumlins when they couldn’t push any more dirt, so they just when over it. When the glaciers melted, the water filled in the wholes between each drumlin creating drowned drumlins or the Boston Harbor Islands. But I also learned that the island never stops changing. Erosion by wind, waves, and water will always keep the island changing. Wind erosion moves a lot of dirt and sand and either carries it to other places or scratches it against rocks in a process called abrasion. Water erosion forms rills and gullies in the ground and transports dirt to other places. Wave erosion uses their strength to hit rocks and landforms and slowly chip away in a process called impact. These are all the things that I learned from the trip.
