Transcript

  • 1. Islands
    This is a presentation made by Group D to make you know more about islands.
    Hope you would like it.
    The Minikoi Islands in Lakshadweep.
  • 2. Introduction
    An island is a piece of ground that is surrounded by water. Water is all around an island. Islands are smaller than continents.
    The largest island in the world is Greenland, unless Australia is believed to be an island.
    The word island comes from Middle English iland, from Old English igland.

  • 3. Facts about Islands
    Earth is home to over 100,000 islands. The 150 largest alone have a landmass equal to the size of Europe.
    One in every ten people on Earth is an islander. More than 600 million people live on islands.
    Hallig Oland is a small island: about 30 people live close together.

  • 4. Types of Islands
    Continental islands
    Oceanic islands
    Desert islands
    Artificial Islands
    Atoll
    Coral Islands
    One of 12 continental islands that make up the Family Group, Dunk Island is a popular family getaway off Mission Beach. 
  • 5. Continental Islands
    To understand a continental island, you need to understand what the continental shelf is. Anyone who's been to the beach knows that the end of land isn't a sudden cliff---around the edges of continents there is a stretch of gradually declining land. This area is called the continental shelf.
    A continental island is simply an island that rests on the continental shelf. Because of this, these islands are always quite close to a given continent. Also, the water level around a continental island is very shallow, typically less than 600 feet.
    The Canadian island of Newfoundland is a continental island.
    The Canadian Island of Newfound Land is a continental island.
  • 6. Oceanic Islands
    Oceanic Islands are not part of continental shelf areas, they are not, and have never been, connected to a continental land mass
    Oceanic islands originate in volcanic action typically associated with the movement of the lithospheric plates. Most typically these are volcanic islands.
    Mariana Islands in the western Pacific Ocean is an example.

  • 7. Desert Island
    A desert island is an island with no people. Typically, a desert island is denoted as such because it exists in a state of being deserted, or abandoned. 
    The word ‘Desert’ does not refer to the hot climatic conditions of the desert.
    You can see an example in the background picture.

  • 8. Artifical Islands
    An Artificial island is an island that has been constructed by humans rather than formed by natural means. They are created by expanding existing islets, construction on existing reefs, or combining several natural islets into a bigger island.
    Dubai is home to several artificial islands projects, including the three Palm Islands projects, The World and the Dubai Waterfront. Only the Palm Jumeirah is inhabited so far.

  • 9. Atoll
    An atoll is a kind of island. It is made when a coral reef forms around an island that sinks over many years. In the end, the land is gone, and only the coral reef continues to grow until it becomes an atoll, an island shaped like a doughnut. 
    Charles Darwin, who is most famous for his theory of evolution, was the first person to find out how atolls form. He said that volcanoes in the ocean sometimes wear away or sink deeper. Coral growing on a volcano likes to be near the surface, and it keeps growing to stay there.
    Most atolls are in the warm parts of the Pacific Ocean or the Indian Ocean.

  • 10. Coral Islands
    A coral island is the result of an atoll whose lagoon has dried up or been filled in with coral sand and detritus*.
    This state is typically the last in the life cycle of an island, the first being volcanic and the second being an atoll. Most of the world's coral islands are in the Pacific Ocean.
    The American territories of Jarvis, Baker and Howland Islands are clear examples of coral islands. Also, some of the islands belonging to Kiribati are considered coral islands.

  • 12. Andaman and Nicobar Islands
    The Andaman and Nicobar Islands is a union territory of India. The name is often shortened to A & N Islands, or ANI.
    It is in the Indian Ocean, in the southern part of the Bay of Bengal. It is made of two island groups - the Andaman Islands and the Nicobar Islands - separating the Andaman Sea to the east, from the Indian Ocean.
    These two groups are separated by the 10° N parallel, the Andamans lying to the north of this latitude, and the Nicobars to the south.
    The capital of this territory is the Andamanese town of Port Blair.
    The territory's population in the 2001 Census of India was 356,152.
    Added together, the total land area of the territory is around 6,496 km² or 2,508 mi², it is larger than the Palestinian territories but smaller than Georgia territory of Abkhazia.
