Floating Islands
A floating island is a mass of floating aquatic plants, mud, and peat ranging in thickness from several centimeters to a few meters. Sometimes referred to as ''tussocks'', ''floatons'', or ''suds'', floating islands are found in many parts of the world. They exist less commonly as an artificial island. Floating islands are generally found on marshlands, lakes, and similar wetland locations, and can be many hectares in size. Natural occurrences Natural floating islands are composed of vegetation growing on a buoyant mat of plant roots or other organic detritus. In aquatic regions of Northwestern Europe, several hundred hectares or a couple thousand acres of floating meadows (German ''Schwingrasen'', Dutch ''trilveen'') have been preserved, which are partly used as agricultural land, partly as nature reserves. They typically occur when growths of cattails, bulrush, sedge, and reeds extend outward from the shoreline of a wetland area. As the water gets deeper the roots no longer ...

Natural Floating Island
Nature is an inherent character or constitution, particularly of the Ecosphere (planetary), ecosphere or the universe as a whole. In this general sense nature refers to the Scientific law, laws, elements and phenomenon, phenomena of the physical world, including life. Although humans are part of nature, human activity or humans as a whole are often described as at times at odds, or outright Anthropocentrism, separate and even superior to nature. During the advent of modern scientific method in the last several centuries, nature became the passive reality, organized and moved by divine laws. With the Industrial Revolution, nature increasingly became seen as the part of reality deprived from intentional intervention: it was hence considered as sacred by some traditions (Jean-Jacques Rousseau, Rousseau, American transcendentalism) or a mere decorum for divine providence or human history (Hegel, Marx). However, a vitalist vision of nature, closer to the pre-Socratic one, got reborn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanic Eruption
A volcanic eruption occurs when material is expelled from a volcanic vent or fissure. Several types of volcanic eruptions have been distinguished by volcanologists. These are often named after famous volcanoes where that type of behavior has been observed. Some volcanoes may exhibit only one characteristic type of eruption during a period of activity, while others may display an entire sequence of types all in one eruptive series. There are three main types of volcanic eruptions. Magmatic eruptions involve the decompression of gas within magma that propels it forward. Phreatic eruptions are driven by the superheating of steam due to the close proximity of magma. This type exhibits no magmatic release, instead causing the granulation of existing rock. Phreatomagmatic eruptions are driven by the direct interaction of magma and water, as opposed to phreatic eruptions, where no fresh magma reaches the surface. Within these broad eruptive types are several subtypes. The we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spiral Island
Spiral Island was a floating artificial island built in Mexico by British artist Richart "Reishee" Sowa. It was destroyed by Hurricane Emily in 2005. A replacement, Joyxee Island, had been open for tours since 2008, but closed after it was damaged by storms and the local authority ordered its removal. Spiral Island was featured in newspapers and TV documentaries around the world, including in Japan and South Korea, as well as an episode of the ''Ripley's Believe It or Not!'' TV series, and on the MTV program '' Extreme Cribs'' in 2011. Spiral Island The first Spiral island was located in a lagoon near Puerto Aventuras, on the Caribbean coast of Mexico south of Cancún; Richart Sowa began constructing it in 1998. He filled nets with empty discarded plastic bottles to support a structure of plywood and bamboo, on which he poured sand and planted numerous plants, including mangroves. The island sported a two-story house, a solar oven, a self-composting toilet, and three beache ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aquaponics
Aquaponics is a food production system that couples aquaculture (raising aquatic animals such as fish, crayfish, snails or prawns in tanks) with hydroponics (cultivating plants in water) whereby the nutrient-rich aquaculture water is fed to hydroponically grown plants. Plants are grown in hydroponics systems, with their roots immersed in the nutrient-rich effluent water. This enables them to filter out the ammonia that is toxic to the aquatic animals, or its metabolites. After the water has passed through the hydroponic subsystem, it is cleaned and oxygenated, and can return to the aquaculture vessels. The size, complexity, and types of foods grown in an aquaponic system can vary as much as any system found in either distinct farming discipline. The main fish grown in aquaponics are tilapia, koi, goldfish, carp, catfish, barramundi, and different types of ornamental fish. The main plants produced include lettuce, pak choi, kale, basil, mint, watercress, tomatoes, p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chinampa
Chinampa ( ) is a technique used in Agriculture in Mesoamerica, Mesoamerican agriculture which relies on small, rectangle, rectangular areas of fertility (soil), fertile arable land to grow agriculture, crops on the shallow lake beds in the Valley of Mexico. The word chinampa has Nahuatl origins, chinampa meaning “in the fence of reeds”. They are built up on wetlands of a lake or freshwater swamp for agricultural purposes, and their proportions ensure optimal moisture retention. This method was also used and occupied most of Lake Xochimilco. The United Nations designated it a Globally Important Agricultural Heritage System in 2018. Although different technologies existed during the Post-classical history, Post-classic and Colonial periods in the basin, chinampas have raised many questions about agricultural production and political development. After the Aztec Empire, Aztec Triple Alliance formed, the conquest of southern basin city-states, such as Xochimilco, was one of th ...

Aztec
The Aztecs ( ) were a Mesoamerican civilization that flourished in central Mexico in the Post-Classic stage, post-classic period from 1300 to 1521. The Aztec people included different Indigenous peoples of Mexico, ethnic groups of central Mexico, particularly those groups who spoke the Nahuatl, Nahuatl language and who dominated large parts of Mesoamerica from the 14th to the 16th centuries. Aztec culture was organized into city-states (''altepetl''), some of which joined to form alliances, political confederations, or empires. The Aztec Empire was a confederation of three city-states established in 1427: Tenochtitlan, the capital city of the Mexica or Tenochca, Tetzcoco (altepetl), Tetzcoco, and Tlacopan, previously part of the Tepanec empire, whose dominant power was Azcapotzalco (altepetl), Azcapotzalco. Although the term Aztecs is often narrowly restricted to the Mexica of Tenochtitlan, it is also broadly used to refer to Nahuas, Nahua polities or peoples of central Pre ...

Inca
The Inca Empire, officially known as the Realm of the Four Parts (, ), was the largest empire in pre-Columbian America. The administrative, political, and military center of the empire was in the city of Cusco.

Later, in 1532, the Spanish Empire, Spanish began the conquest of the Inca Empire, and by 1572 Neo-Inca State, the last Inca state was fully conquered. From 1438 to 1533, the Incas incorporated a large portion of western South America, centered on the Andes, Andean Mountains, using conquest and peaceful assimilation, among other methods. At its largest, the empire joined modern-day Peru with what are now western Ecuador, western and south-central Bolivia, northwest Argentina, the southwesternmost tip of Colombia and Incas in Central Chile, a large portion of modern- ...
