A peninsula is a landform that extends from a mainland and is surrounded by water on most sides. Peninsulas exist on each continent. The largest peninsula in the world is the Arabian Peninsula .
11-465: The Freycinet Peninsula is a large peninsula located on the eastern coast of Tasmania , Australia. The peninsula is located north of Schouten Island and is contained within the Freycinet National Park . The locality of Freycinet is in the local government area of Glamorgan–Spring Bay in the south-east region of Tasmania. The locality is about 110 kilometres (68 mi) north-east of
22-488: The Friendly Beaches Reserve , and Wineglass and Honeymoon bays. It covers an area of 65 square kilometres. Two sandpits connect the peninsula to the mainland. It is surrounded by Schouten Passage and Island on its southern tip and Oyster Bay on its western side. The "Vanderlyn Island" was the last sighting of Australia by Abel Tasman in 1642 before turning east to New Zealand. The first landing by Europeans
33-857: The body of water does not have to be an ocean or a sea. A piece of land on a very tight river bend or one between two rivers is sometimes said to form a peninsula, for example in the New Barbadoes Neck in New Jersey , United States. A peninsula may be connected to the mainland via an isthmus , for example, in the Isthmus of Corinth which connects to the Peloponnese peninsula. Peninsulas can be formed from continental drift , glacial erosion , glacial meltwater , glacial deposition , marine sediment , marine transgressions , volcanoes, divergent boundaries or river sedimentation. More than one factor may play into
44-489: The formation of a peninsula. For example, in the case of Florida , continental drift, marine sediment, and marine transgressions were all contributing factors to its shape. In the case of formation from glaciers (e.g., the Antarctic Peninsula or Cape Cod ), peninsulas can be created due to glacial erosion , meltwater or deposition . If erosion formed the peninsula, softer and harder rocks were present, and since
55-466: The glacier only erodes softer rock, it formed a basin . This may create peninsulas, and occurred for example in the Keweenaw Peninsula . In the case of formation from meltwater, melting glaciers deposit sediment and form moraines , which act as dams for the meltwater. This may create bodies of water that surround the land, forming peninsulas. If deposition formed the peninsula, the peninsula
66-487: The peninsula in the 1820s and 1830s at Wineglass Bay , Refuge Bay, Bryans Beach and Coles Bay . Peninsula The word peninsula derives from Latin paeninsula , from paene 'almost' and insula 'island'. The word entered English in the 16th century. A peninsula is generally defined as a piece of land surrounded on most sides by water. A peninsula may be bordered by more than one body of water, and
77-468: The sediment is deposited, forming a delta peninsula. Marine transgressions (changes in sea level) may form peninsulas, but also may affect existing peninsulas. For example, the water level may change, which causes a peninsula to become an island during high water levels. Similarly, wet weather causing higher water levels make peninsulas appear smaller, while dry weather make them appear larger. Sea level rise from global warming will permanently reduce
88-469: The town of Swansea . The peninsula is a large, dramatic land formation carved into Tasmania's eastern coastline. Known for its pink granite mountain range, The Hazards , and its sheltered, white sand beaches, the peninsula is the location for Freycinet National Park, the first national park to be declared in Tasmania, along with Mt Field National Park . Also on the peninsula is the village of Coles Bay ,
99-552: The volcano erupts near shallow water. Marine sediment may form peninsulas by the creation of limestone . A rift peninsula may form as a result of a divergent boundary in plate tectonics (e.g. the Arabian Peninsula ), while a convergent boundary may also form peninsulas (e.g. Gibraltar or the Indian subcontinent ). Peninsulas can also form due to sedimentation in rivers. When a river carrying sediment flows into an ocean,
110-518: Was by Captain Weatherhead of the transport ship Matilda on 27 July 1791. Due to the narrow northern isthmus , Weatherhead and Tasman mistook it for an island. Nicholas Baudin named the peninsula after French explorer Louis de Freycinet . Baudin also named Cape Baudin, Cape Faure, Cape Forestier and Thouin Bay, although that bay is now known as Wineglass Bay. Shore-based bay whaling stations operated on
121-538: Was composed of sedimentary rock , which was created from a large deposit of glacial drift . The hill of drift becomes a peninsula if the hill formed near water but was still connected to the mainland, for example during the formation of Cape Cod about 23,000 years ago. In the case of formation from volcanoes, when a volcano erupts magma near water, it may form a peninsula (e.g., the Alaskan Peninsula ). Peninsulas formed from volcanoes are especially common when
