Types of Archipelago

Archipelagos may be found isolated in bodies of water or neighboring a large land mass. For example, Scotland has more than 700 islands surrounding its mainland which constitute an archipelago. Archipelagos are often volcanic, forming along island arcs generated by subduction zones or hotspots, but may also be the result of erosion, deposition and land elevation. It really means a broad area of water containing several islands. By its geological origin, islands forming archipelagos can be referred to as oceanic islands, continental fragments and continental islands. Oceanic islands are mainly of volcanic origin. Continental fragments correspond to land masses that have separated from a continental mass due to tectonic displacement. Finally, sets of islands formed close to the coast of a continent are considered continental archipelagos when they form part of the same continental shelf so islands are just exposed continental shelf.

The five largest modern countries that are mainly archipelagos are Indonesia, Japan, the Philippines, New Zealand and the United Kingdom. The largest archipelagic state in the world, by area and population, is Indonesia. The archipelago with the most islands is the Archipelago Sea in Finland.]]

Famous quotes containing the words types of and/or types:

    Our children evaluate themselves based on the opinions we have of them. When we use harsh words, biting comments, and a sarcastic tone of voice, we plant the seeds of self-doubt in their developing minds.... Children who receive a steady diet of these types of messages end up feeling powerless, inadequate, and unimportant. They start to believe that they are bad, and that they can never do enough.
    Stephanie Martson (20th century)

    Our major universities are now stuck with an army of pedestrian, toadying careerists, Fifties types who wave around Sixties banners to conceal their record of ruthless, beaverlike tunneling to the top.
    Camille Paglia (b. 1947)
