Long Island Is An Example Of What Glacial Landform? (Solved)

Long Island is home to a huge number of big rocks known as “glacial erratics,” which are formed as a result of the moraine deposits. However, many of these stones may be found in the thin ground moraine layer that has been formed on the surface north of the terminal moraines as a result of the melting of the ice cap.

What type of glacial landform is Long Island?

Long Island, which is a component of the Outer Lands area, is mostly composed of four spines of glacial moraine, with a broad, sandy outwash plain extending towards its barrier islands and the Atlantic Ocean on the eastern side.

What landform is Long Island a part of?
