What is a Peninsula Landform?

A peninsula is a substantial portion of land that extends from the mainland and has water on three sides.

How are Peninsulas Formed?

A peninsula can be formed by rising or falling sea level that may expose or cover portions of land to form a peninsula. An uplift or fall of landmass may also help to form a peninsula. A separation of landmasses over millions of years can create a penisula.

How Large is a Peninsula?

A small peninsula may be a few miles long, or more. A very large peninsula may be hundreds of miles in length and width.

Where Can a Peninsula Be Found?

A peninsula can be found on a seacoast. A lake or any large body of water may have a peninsula on the coastline.

Florida Peninsula is the portion of Florida that extends south from the mainland of the southeastern US. It is approximately 300 miles long and 160 miles across at its widest point, with the Gulf of Mexico on the west coast and the Atlantic Ocean to the east. The entire state of Michigan sits on two large peninsulas, bordered by 4 of the Great Lakes.

The Lower Peninsula has Lake Michigan to the west, Lake Huron along the northeast coast and Lake Erie in the southeast corner. The Upper Peninsula meets Lake Superior in the north and Lake Michigan on the southern coast. The two peninsulas are connected by the Mackinac Bridge, crossing 5 miles over the Straits of Mackinac. The Italian Peninsula extends over 250 miles southeast from mainland Europe into waters of the Mediterranean Sea.

Italy occupies almost all of the peninsula, with less than one half of one percent held by the micro-nation of San Marino and the Vatican City in Rome. The Korean Peninsula extends south from the east coast of Asia. The peninsula is divided between North and South Korea, and by convention includes all of the land north to the Chinese border.

From the northernmost point to the southern tip is almost 600 miles measured from point to point. The southeast coast lies just over 100 miles from the main coast of Japan. The Arabian Peninsula of western Asia is 1,700 miles long and from 750 to 1,240 miles wide.

Considered to be the world’s largest peninsula, it is divided between 9 Arab countries, the largest being Saudi Arabia. The peninsula was created when a separation of landmass occurred where the Red Sea is now located at least 23 million years ago.
