=How Boston Harbor Islands Were Formed=

=
Once upon a time there was a very giant __ glacier __ that moved rapidly faster than regular back and forth. It was a continental glacier that moved through Canada and parts of the United States. This glacier picked up __T____ ill __ which was tiny rocks, regular rocks and even huge boulders. When the glacier melted it left piles of rocks, sand, dirt, silt, clay, & boulders in an upside-down form shaped like a spoonful of land called a __ drumlin. __This drumlin then turned into a __ drowned drumlin __ and became surrounded by water like an island, which soon became the Boston Harbor. When it was surrounded by ice the ice melted and formed water around the drumlin.=====

=
The __ erosion by the waves __ started re-shaping the island and everyday it will look a little bit different. The __ impact __ from the waves and the sand scraped the sides of the boulders and rocks on the elevated side of the drowned drumlin. The abrasion that the glacier made was seen very clearly after the glacier melted. __ Abrasion __ is when the under side of the glacier has many rocks, and boulders and it scratches the bedrock. After the glacier is gone it does an action called __ deposition __, which means it is depositing the sediment and it forms land such as drumlins. The __ beach __ was formed by the erosion by waves it was formed that way because of impact from water and into the rocks/cliffs and stones. It smoothens out rocks into stones and cliffs into boulders, which eventually creates sand. Then __ long shore drift __ came along and the direction of the current moved in a pattern it’s simply a transition of sediments that is generated by wave and current action. After long shore drift came and went the erosion formed a __ spit __, which is a stuck out piece of land.=====

=
The __ erosion by wind __ then took the small grains of dirt and sand and very small rocks was pushed by the wind and moved around the island/s. Most of the dirt that is pushed around and blown around it is called loess.=====

=
The erosion by wind is not very strong this is why __ erosion by water __ is the most effective ingredient of erosion. Rain and oceans and even rivers erode the land. Rain creates __ runoff __ that flows into a body of water such as a river or an ocean. The runoff creates __ rills __ which are small indents in the mountain or hill that look like lines of water that travel downward towards the bottom of the hill. Another type of rill is a __ gully __, which is much bigger and leaves marks in the hill/mountain as well. In the end all three types of erosion created what we like to now call the Boston Harbor islands.====== To help you VOCABLUARY- Glacier: A very large mound of ice and snow that can be as big as America. Till: Sediment that is inside the glacier before it melts. Drumlin: An island that is left behind by a glacier Drowned Drumlin: A drumlin that is fully eroded and located underwater Erosion by waves: The process of erosion that the waves create Impact: The before and after effect Abrasion: When the rocks under the glacier and other hard objects scratch the bedrock Deposition: When the glacier deposits sediment etc. Beach: An area on the coast that has sand and rocks Sea life etc. Long shore drift: The process that makes the current, the angles of the waves hitting the sand Spit: A piece of land that sticks out because the rest of the land around it is eroded Erosion by wind: The process of erosion that wind creates Erosion by water: The erosion that water creates Runoff: The rainwater usually from the top of a hill or drulin. Etc.. That runs off into the river/body of water Rills: The lines the runoff makes in the earth Gully: bigger type of rill see rill ^
