Floating island
As a floating island is called a natural structure that drives the water surface and is not connected to the bottom of the water. Artificial floating islands are also known as Pontoon.
Floating islands are no land masses and therefore no real islands.
Floating islands can be several hundred meters long. From time to time they are on large rivers ( such as the Amazon ) or to find on a lake or inland sea. In the open sea are currently no floating islands known. For longer existing larger floating islands and vegetation may occur, to small trees. Moves is a floating island by the wind or by the flow.
Large demolition pieces of ice edge in the Arctic and Antarctic can also reach the island proportions.

Formation
On the origin of floating islands Miscellaneous can help. Some were once part of the shore and have, usually after natural disasters, dissolved and washed away. Larger pieces can abort have retained their growth and have bushes or trees. Others also be caused by the growing interdependence of plant material. In equatorial regions, a floating island consist of accumulations of broken coral. These can reach a considerable size, but are not very stable and do not show any growth in the rule. At the time of sailing was superstitious sailors of the Sargasso Sea in the Atlantic Ocean, east of Florida and south of Bermuda, often mistaken for floating islands and decked out with weird stories. A growing on the water surface on the shore vegetation is called quaking.
Swimming
Thus, a floating island without boot -shaped curvature, thus protrudes above the water level, the already dipping into the water supply must meet the buoyancy by Archimedes provide for the total weight of the island. Their average density must therefore be significantly smaller than that of water ( ρ = 1 g / cm ³).
There are hardly any solids lighter than water, even water -soaked wood from falling, that is to be expected with a certain proportion of gas in the island of floating bodies; in dead and living wood and hollow plant parts such as stems of reeds or bladderwrack. Anaerobic bacterial decomposition in the bottom of the island provides methane and CO2 in the form of bubbles, which get stuck for a while in Bodenfilz or plant material.
Centimeters Small Floating islands are formed by mold - grass stains on about fruit juice. In this size range, however, dominates the surface tension of water lift. Is the edge of the patch hydrophobic it is not wetted, but only the liquid surface is dented. - Palm-sized flocs with digester gas bubbles can float in tilted lakes and ponds.
Mythology
In Greek mythology, Delos was originally a floating island. At the request of Hera Leto could not give birth on the mainland and brought her children Apollo and Artemis therefore on Ortygia (later " Delos" ) to the world. In gratitude, Zeus ( the father of the children ) made the island to the ( geographical ) center of Greece.
The floating island of Aiolia is in Homer's Odyssey is the location of the Greek wind god Aeolus. You should have lain off Sicily.
Examples of artificial floating islands
Urus
Artificial floating islands that were woven from Totora, there is in Peru on Lake Titicaca. Their ( former ) inhabitants are called Urus. Originally the islands were created at a time when the inhabitants had before their warlike neighbors, the Incas and Kollas protect. The indigenous inhabitants still speak the ancient languages Quechua and Aymara. The floating islands have become a tourist destination, and you can stay on them.
Spiral Iceland
Richie Sowa, a musician, artist and carpenter, constructed near Cancun, Mexico floating islands which float from empty plastic bottles filled networks is. Spiral Iceland I was born from 1998 to 2005, but was then thrown from a hurricane on land. Spiral Iceland 2 is currently under construction.
Examples of natural floating islands
In the Danube Delta Biosphere Reserve there are many floating islands ( Plaur ). In fact, the true topography of the delta, whether or not the country, not sufficiently explored to date.
Hautsee
The floating island on the Thuringian Hautsee in Bad Salzungen / Dönges was probably due to sedimentation processes and is the namesake of the lake.
Schollener lake
Small Arber Lake
In Small Arber Lake, a lake in the Bavarian Forest to 918 meters above sea level, there are three floating islands of grass. By damming the lake as a result of Holztrift these islands have solved as a ground cover from the shore. At 1.5 to 3.5 meters thick islands bog plants and small trees have settled. In 1959, the lake was designated with the islands as a nature reserve.
Ungeheuersee
The floating islands in the Ungeheuersee, a Hochmoorsee in the Rhine Palatinate in Bad Durkheim, were reported together with the lake in the 1930s as a natural monument. The islands are grasses, orchids and pine trees.
Princess hole
The Princess hole belongs to the pond area Ilmenau in the Thuringian Forest. It was created by a sinkhole. In the middle drives a small island. The area is a nature reserve and is a bird protection area.
Switzerland
The small Lützelsee between Zurich and Greifensee in Canton Zurich is a kettle hole and communicating with the moorland in the area under protection. The islands are caused by plant sticks that dissolve from the shore. There are also in Switzerland only in Barchetsee at Neunforn floating islands, which consist of overgrown lumps of peat.
