An island is land or land surrounded by water with an area smaller than a continent and larger than a coral reef. A collection of several islands is called the islands or archipelago (English: archipelago).
The United Nations Convention on the International Law of the Sea 1982 (UNCLOS '82) article 121 defines an island as "land formed naturally and surrounded by water, and is always above the water level at high tide". In other words, an island should not sink at high tide. The implication is that the conditions that must be met in order to be called an 'island' are:
formed naturally, not reclaimed land
surrounded by water, both salt water (sea) and fresh water
always above the high tide line. Thus, sand, mud or coral that is submerged in high tide, according to the above definition cannot be called an island. Likewise, scorched mud or mud exposure overgrown with mangroves, which are submerged by high tides, even though the mangrove trees always appear above the water surface. Islands have various names in Indonesia. The non-standard form is a pulo. The word borrowing from Sanskrit is also often used, nusa. Off the east coast of Java people refer to the small island as the gili.
In Indonesia, by definition, a small island is an island that has an area of less than or equal to 10,000 km².
Differences with continents
Continents and islands are words to describe land areas. Depending on the world map and globe, each continent can be isolated from the island. The difference is not only in size but also in other aspects.
The most important difference between an island and a continent is their size. Islands are often depicted as land that is smaller than a continent and surrounded by water on all sides. However, this definition does not state to what size an island will be called a continent. Sometimes, many small islands are grouped together and referred to as an archipelago. Referring to the definition of an island, Australia is actually an island, but is labeled as a continent. A continent is a very large land mass and is even larger than an island. A continent may contain a large number of islands and may include many countries; they can also be allocated by the state on physical and political boundaries. Instead, the two sides of the island are depicted as small continents surrounded by ponds. On the other hand, Greenland (with an area of 2,160,230 km2) is a giant island and has a size much larger than most countries in the world still being called an island. , fauna and flora (animals and plants). Because the land was so vast, many people from different cultures could live together on the same continent within their borders. This island can only accommodate a small group of people at a time. It is this main difference between Greenland and Australia, Australia is almost four times bigger than Greenland. Aboriginal people are limited, while peoples in Greenland, namely groups of people (Inuit) can be found throughout the Arctic, including parts of Canada, the United States, and Russia. One island can be renamed, while continents adjacent to each other can be called one. It is often associated with Europe and Asia, as the two continents are connected by land: the name "Eurasia" connects Europe and Asia, although due to political and cultural differences, not every continent is always so. Most cultures on this continent are different from other continents. The island may also have a completely different culture from the continent in which it is located, or if the island is part of a particular continent or country, it may be associated with the management and culture of that continent. In other words, continents can be identified
