Archipelago and island game quiz online - The geology and origin of islands are important factors in their formation. Volcanoes form islands from seafloors; the Hawaiian Islands, Canary Islands, Azores, Aleutian Islands, and other volcanic island formations are examples of archipelagoes. Sea level rise can also create islands from high areas.
The word archipelago derives from the Greek words arkhi and pelagos, and it also features in Italian. Ancient Greeks called the Aegean Sea an archipelago. Historically, archipelago was used to describe large groups of islands, mostly volcanic in origin, separated from neighboring continents. The Hawaiian Islands and Easter Island are examples of archipelagos.
The Hawaiian Islands have a unique conical and mountainous shape and were formed by the continuous eruption and building of layer upon layer. They rise from the sea at an average of only a few meters to nearly 5000 feet in elevation. In between, the Hawaiian islands are covered with twelve terrace levels. Hence, the islands are the most eustatic of all volcanic regions in the world. Their geological history is a fascinating one.
The geology of the Galapagos archipelago begins below the sea and emerges above the ocean floor. This is where three major tectonic plates meet. The islands are relatively young; Isabela and Fernandina are less than a million years old; and San Cristobal and Espanola are between three and five million years old. The archipelago provides a unique example of the evolution of an ocean island from a volcanic region in the west to an older, non-volcanic island in the east.
The Philippines is an archipelago located in Southeast Asia, approximately halfway between Australia and Asia. It is divided into three main parts: the Sunda Shelf, the Sahul Shelf, and the area of recent tectonic activity. The vast majority of Indonesia's islands lie within 10 degrees of the Equator. Average temperatures are around 80 degrees Fahrenheit or 21 degrees Celsius, and annual rainfall varies greatly. Islands in the Philippines makes it an important destination for tourists from around the world.
The Conservation of Archipelago and Islands focuses on preserving the archipelago's flora and fauna. Organizations are especially interested in preserving key species that are in imminent or specific danger. Current research focuses on filling in information gaps about Mediterranean chameleons and Golden jackals for example. There are numerous endangered species of archipelago and island flora and fauna that are protected by law. The great thing about them is, although a lot has been destroyed, they still remain the home to many endemic species around the world.
The archipelago and island nations of the world face a myriad of challenges. Human habitat, sanitation, and land use are all prone to problems. Most of the houses are built below their carrying capacity and many are located in areas subject to flooding. Urbanization has created overcrowding and makeshift construction in these islands and resulted in health concerns. Although many islands have implemented tree replanting programs, the issues of urban pollution remain unresolved.
