Island in the context of Tempeh

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.

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.

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.

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.

Kasos (/ˈkɑːsoʊs/; 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.

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.

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):

Determining the boundaries between the continents is generally a matter of geographical convention and consensus. Several slightly different conventions are in use. The number of continents is most commonly considered seven (in English-speaking countries) but may range as low as four when Afro-Eurasia and the Americas are both considered as single continents. An island can be considered to be associated with a given continent by either lying on the continent's adjacent continental shelf (e.g. Singapore, the British Isles) or being a part of a microcontinent on the same principal tectonic plate (e.g. Madagascar and Seychelles). An island can also be entirely oceanic while still being associated with a continent by geology (e.g. Bermuda, the Australian Indian Ocean Territories) or by common geopolitical convention (e.g. Ascension Island, the South Sandwich Islands). Another example is the grouping into Oceania of the Pacific Islands with Australia and Zealandia.

There are three overland boundaries subject to definition:

This is a list of continental landmasses, continents, and continental subregions by population. For statistical convenience, the populations of continental landmasses also include the populations of their associated islands.

Long Island is a densely populated continental island in southeastern New York state, extending into the Atlantic Ocean. It constitutes a significant share of the New York metropolitan area in both population and land area. The island extends from New York Harbor 118 miles (190 km) eastward into the ocean with a maximum north–south width of 23 miles (37 km). With a land area of 1,401 square miles (3,630 km), it is the largest island in the contiguous United States and the 11th largest island in the U.S.

Long Island is divided among four counties with Kings (Brooklyn), Queens, and Nassau counties occupying its western third and Suffolk County its eastern two-thirds. To what extent Brooklyn and Queens are considered with Long Island is a matter of debate. Geographically, both Kings and Queens county are located on the Island, but some argue they are culturally separate from Long Island. Long Island may refer both to the main island and the surrounding outer barrier islands. Long Island is separated from Manhattan Island and the Bronx by the East River tidal estuary in the west part of the island. North of the island is Long Island Sound, across which lie Westchester County, New York, and the state of Connecticut. Across the Block Island Sound to the northeast is the state of Rhode Island. Block Island, which is part of Rhode Island, and numerous smaller islands extend farther into the Atlantic Ocean. To the extreme southwest, Long Island, at Brooklyn, is separated from Staten Island and the state of New Jersey by Upper New York Bay, The Narrows, and Lower New York Bay.

Nea Kameni is a small, uninhabited Greek island of volcanic origin located in the Aegean Sea, within the flooded Santorini caldera. Nea Kameni (new burnt) and the neighbouring small island Palea Kameni (old burnt) have formed over the past two millennia through repeated eruptions of dacite lava and ash. The Roman historian Cassius Dio records in the year 47 CE "This year a small islet, hitherto unknown, made an appearance close to the island of Thera." Cassius' report may refer to Palaia Kameni. Pliny the Elder reported the emergence of a new island on July 8, in the year of the consulship of M. Junius Silanus and L. Balbus, thus 19 CE.

Major eruptions over the past 300 years took place in 1707–1712, 1866–1870, 1925–1928, and 1939–1941. The last small eruption happened in 1950 and involved lava dome extrusion.

Christiana (Greek: Χριστιανά) is a group of three volcanic Greek islands in the Cyclades.

The group is located about 16 km (10 miles) southwest of Santorini and is made up of the islands Christiani (Χριστιανή, the largest one), Eschati (Εσχάτη) and Askania (Ασκανιά), belonging to the same submarine volcanic edifice, which is assumed to have been dormant since the Early Pleistocene. The islands' area is about 2.35 km.

This is a list of islands of Italy. There are nearly 450 islands in Italy, including islands in the Mediterranean Sea (including the marginal seas: Adriatic Sea, Ionian Sea, Libyan Sea, Ligurian Sea, Sea of Sardinia, Tyrrhenian Sea, and inland islands in lakes and rivers. The largest island is Sicily with an area of 25,711 km (9,927 sq mi). The outlying islands of Italy make up an official region of Insular Italy with an area of 49,801 km (19,228 sq mi).

World Heritage Sites are landmarks and areas with legal protection under an international treaty administered by UNESCO for having cultural, historical, or scientific significance. The sites are judged to contain "cultural and natural heritage around the world considered to be of outstanding value to humanity".

To be selected, a World Heritage Site is nominated by its host country and determined by the UNESCO's World Heritage Committee to be a unique landmark which is geographically and historically identifiable, having a special cultural or physical significance, and to be under a sufficient system of legal protection. World Heritage Sites might be ancient ruins or historical structures, buildings, cities, deserts, forests, islands, lakes, monuments, mountains, wilderness areas, and others.

Mainland Australia is the main landmass of the Australian continent, excluding the Aru Islands, New Guinea, Tasmania, and other Australian offshore islands. The landmass also constitutes the mainland of the territory governed by the Commonwealth of Australia, and the term, along with continental Australia, can be used in a geographic sense to exclude surrounding continental islands and external territories. Generally, the term is applied to the states of New South Wales, Queensland, South Australia, Victoria, and Western Australia, as well as the Australian Capital Territory, Jervis Bay Territory, and Northern Territory.

The term is typically used when referring to the relationship between Tasmania and the other Australian states, in that people not from Tasmania are referred to as mainlanders. Tasmania has been omitted on a number of occasions from maps of Australia, reinforcing the divide between Tasmania and the mainland. The 1982 Commonwealth Games in Brisbane left Tasmania off the map of Australia during the opening ceremony, as did the designs of the Australian Swim Team uniform for the 2014 Commonwealth Games in Glasgow.

This list includes all islands (insular landmasses) in the world larger than 1,000 km (390 sq mi). For size and location reference, the four continental landmasses are also included. All landmasses are arranged in descending order.

This is a list of islands in the world ordered by population, which includes all islands with more than 100,000 people. For comparison, continental landmasses are also shown, in italics. The population of the world's islands is over 730 million, approximately 9% of the world's total population. Of those, only Java (Indonesia) and Honshu (Japan) have populations over 1% of the global population.
