Is Long Island a glacial Drumlin?
Spectacle and Long Islands are two of the drumlins that can be found in Boston Harbor Islands National Recreation Area (Massachusetts). Drumlins are hills of sediment (generally a quarter of a mile or more in length) that have been streamlined by glacier flow.Thus, they are often elongated.
What features of Long Island are examples of glacial deposition?
Many large boulders, or “glacial erratics”, are found on Long Island as part of the moraine deposits. These boulders are most abundant on the terminal moraines, although many occur in the thin ground moraine layer deposited on the surface north of the terminal moraines as the ice melted.
What type of depositional feature is Long Island?
outwash plain
The moderately flat surface that extends southward from the Ronkonkoma and Harbor Hill moraines to the south-shore bays is called an outwash plain. It is mainly a depositional feature composed of and underlain by well sorted sand and gravel deposited by streams that were fed by glacial melt water.
Is Long Island an end moraine?
Why are they in the spot they are in? About 22,000 years ago, a glacier crept up and covered the northern half of Long Island. The glacier stopped there for a while. The melting edge dropped rock pieces in a long pile, called a terminal moraine, in the middle of Long Island.

How is Long Island evidence of glaciation?
The upper portion of Long Island’s geological layers were formed between the Upper Cretaceous Period (72 to 100 million years ago) and Pleistocene Epoch (.The change in gradient and topographic make up from north to south is evident of glacial movement, so the Long Island of today was shaped by glaciation.
What are glacial depositional features?
U-shaped valleys, hanging valleys, cirques, horns, and aretes are features sculpted by ice. The eroded material is later deposited as large glacial erratics, in moraines, stratified drift, outwash plains, and drumlins.
Which is the depositional feature of a glacier?
Option B: Moraines comprise of sediments, rocks, debris, dirt and more which are transmitted by the glaciers when moves down the mountains slowly. It is generally, the material left behind by a moving glacier. Hence, it is the depositional feature of glacier.

Why is it called Long Island Sound?
The ice tore a deep gouge in the land and formed Lake Connecticut. Then, as sea levels and sediments rose and shifted, the lake receded while rivers and ocean waters took its place and so was born the Long Island Sound.
