⭐ Core Definition: Island

An island or isle is a piece of land, distinct from a continent, completely surrounded by water. There are continental islands, which were formed by being split from a continent by plate tectonics, and oceanic islands, which have never been part of a continent. Oceanic islands can be formed from volcanic activity, grow into atolls from coral reefs, and form from sediment along shorelines, creating barrier islands. River islands can also form from sediment and debris in rivers. Artificial islands are those made by humans, including small rocky outcroppings built out of lagoons and large-scale land reclamation projects used for development.

Islands are host to diverse plant and animal life. Oceanic islands have the sea as a natural barrier to the introduction of new species, causing the species that do reach the island to evolve in isolation. Continental islands share animal and plant life with the continent they split from. Depending on how long ago the continental island formed, the life on that island may have diverged greatly from the mainland due to natural selection.

Island in the context of List of islands of Greece

Greece has many islands, with estimates ranging from somewhere around 1,200 to 6,000, depending on the minimum size to take into account. The number of inhabited islands is variously cited as between 166 and 227.

The largest Greek island by both area and population is Crete, located at the southern edge of the Aegean Sea. The second largest island in area is Euboea or Evvia, which is separated from the mainland by the 60 m wide Euripus Strait, and is administered as part of the Central Greece region. After the third and fourth largest Greek islands, Lesbos and Rhodes, the rest of the islands are two-thirds of the area of Rhodes, or smaller.

Island in the context of Continent

A continent is any of several large terrestrial geographical regions. Continents are generally identified by convention rather than any strict criteria. A continent could be a single large landmass, a landmass and nearby islands either on or beyond its continental shelf, or a part of a larger landmass, as in the case of Asia and Europe within Eurasia. Due to these varying definitions, the number of continents varies, up to seven or as few as four. Most English-speaking countries recognize seven continents. In order from largest to smallest in area, these seven are Asia, Africa, North America, South America, Antarctica, Europe, and Australia (or sometimes Oceania or Australasia). Different variations with fewer continents merge some of these regions; examples of this are merging Asia and Europe into Eurasia, North America and South America into the Americas (or simply America), and Africa, Asia, and Europe into Afro-Eurasia.

Oceanic islands are occasionally grouped with a nearby continent to divide all the world's land into geographical regions. Under this scheme, most of the island countries and territories in the Pacific Ocean are grouped together with the continent of Australia to form the geographical region of Oceania.

Island in the context of Island country

An island country, island state, or island nation is a country whose primary territory consists of one or more islands or parts of islands. Approximately 25% of all independent countries are island countries. Island countries are historically more stable than many continental states but are vulnerable to conquest by naval superpowers. Indonesia is the largest and most populated island country in the world (and the fourth most populated country overall).

There are great variations between island country economies: they may rely mainly on extractive industries, such as mining, fishing and agriculture, and/or on services such as transit hubs, tourism, and financial services. Many islands have low-lying geographies and their economies and population centers develop along coast plains and ports; such states may be vulnerable to the effects of climate change, especially sea level rise.

Island in the context of Albanian Ionian Sea Coast

The Albanian Ionian Sea Coast (Albanian pronunciation: [brɛˈɡdɛ:ti jˈɔn]Albanian: Bregdeti Jon) is a coastline of the north-eastern Ionian Sea, that encompasses the south-western border of the Republic of Albania, stretching from the southern half of Karaburun Peninsula, across the historical region of Labëria, the city of Sarandë, the mountains of the Ceraunians, and the Albanian Riviera, to the Lake of Butrint, where the Strait of Corfu separates the country from Greece.

Albania is located in Southern and South-eastern Europe in the western section of the Balkan Peninsula. It borders on Montenegro to the north-west, Kosovo to the north-east, North Macedonia to the east, Greece to the south, and the Mediterranean Sea to the west. The coastline occupies a total length of 446 kilometres (277 mi) and explicitly marked by a mountainous landscape supplied with deep bays, numerous islands, high cliffs, rocky and sandy coasts and unique marine life.

Island in the context of Kassos

Kasos (/ˈkɑːss/; Greek: Κάσος, pronounced [ˈka̠so̞s]), also Casos, is a Greek island municipality in the Dodecanese. It is the southernmost island in the Aegean Sea, and is part of the regional unit Karpathos-Kasos. The capital of the island is Fri. As of 2021, its population was 1,223.

Island in the context of Continental shelf

A continental shelf is a portion of a continent that is submerged under an area of relatively shallow water, known as a shelf sea. Much of these shelves were exposed by drops in sea level during glacial periods. The shelf surrounding an island is known as an "insular shelf."

The continental margin, between the continental shelf and the abyssal plain, comprises a steep continental slope, surrounded by the flatter continental rise, in which sediment from the continent above cascades down the slope and accumulates as a pile of sediment at the base of the slope. Extending as far as 500 km (310 mi) from the slope, it consists of thick sediments deposited by turbidity currents from the shelf and slope. The continental rise's gradient is intermediate between the gradients of the slope and the shelf.

Island in the context of Landmass

A landmass, or land mass, is a large region or area of land that is in one piece and not noticeably broken up by oceans. The term is often used to refer to lands surrounded by an ocean or sea, such as a continent or a large island. In the field of geology, a landmass is a defined section of continental crust extending above sea level.

Continents are often thought of as distinct landmasses and may include any islands that are part of the associated continental shelf. When multiple continents form a single contiguous land connection, the connected continents may be viewed as a single landmass. Earth's largest landmasses are (starting with largest):
