"Long Island." Long Island was not always the separate piece of land it is today. Originally, it's base was part of Southern Connecticut, which slid under Long Island. The middle layer was formed during the age of the dinosaurs as a result of deposits left by ancient rivers. These deposits were sand, clay, and gravel. The top layer of Long Island was made by large sheets of ice called a glaciers. These glaciers were formed when snow fell but it was too cold to melt, which created blocks of ice. The first glacier came 60,000 years ago and was followed by another glacier 21,000 years ago. http://www.powertolearn.com/li_history/natural.html Jul 17 06, 7:05 PM
