Motu Nui
Motu Nui is the largest of the Islet, islets located off the southwestern coast of Easter Island (Rapa Nui) and constitutes the westernmost point of Chile. Covering an area of 3.9 hectares, it is the summit of a submerged volcanic mountain that rises over 2,000 meters from the seafloor. Motu Nui is one of the five satellite islets of Easter Island and is notable for being among the three closest landmasses to Point Nemo, the oceanic pole of inaccessibility. The other two are Ducie Island (Pitcairn Islands) and Maher Island (Antarctica). Historically, Motu Nui played a central role in the ''Tangata manu'' ("bird-man") cult, a religious tradition that developed after the moai-building period and before the widespread adoption of Christianity in the 1860s. Each year, representatives (''Hopu'') from different clans would swim to Motu Nui to await the arrival of the manutara, ''manutara'' (sooty tern). The first Hopu to retrieve an egg would return to Easter Island and present it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Easter Island 11
Easter, also called Pascha (Aramaic: פַּסְחָא , ''paskha''; Greek: πάσχα, ''páskha'') or Resurrection Sunday, is a Christian festival and cultural holiday commemorating the resurrection of Jesus from the dead, described in the New Testament as having occurred on the third day of his burial following his crucifixion by the Romans at Calvary . It is the culmination of the Passion of Jesus, preceded by Lent (or Great Lent), a 40-day period of fasting, prayer, and penance. Easter-observing Christians commonly refer to the last week of Lent, before Easter, as Holy Week, which in Western Christianity begins on Palm Sunday (marking the entrance of Jesus in Jerusalem), includes Spy Wednesday (on which the betrayal of Jesus is mourned), and contains the days of the Easter Triduum including Maundy Thursday, commemorating the Maundy and Last Supper, as well as Good Friday, commemorating the crucifixion and death of Jesus. In Eastern Christianity, the same events are c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rano Kau
Rano Kau is a tall extinct volcano that forms the southwestern headland of Easter Island, a Chilean island in the Pacific Ocean. It was formed of basaltic lava flows in the Pleistocene with its youngest rocks dated at between 150,000 and 210,000 years ago. The crater Rano Kau has a crater lake which is one of the island's only three natural bodies of fresh water. The lake is located approximately above sea level, but is more than below the highest of the crater's ridges. The volcanic cone is largely surrounded by water, and much of it has been eroded back to form high sea cliffs which at one point (''te kari kari'') have started to bite into the crater wall. The inside walls of the crater are sloped at an angle of between 65° (steepest, near the crest) and 45° (gentlest, at the lake shore). From the ruins of the ceremonial village of Orongo the cliff face drops to the southwest at an angle of 50° to the sea shore some below. On its northern side, the volcano ...

Overfishing
Overfishing is the removal of a species of fish (i.e. fishing) from a body of water at a rate greater than that the species can replenish its population naturally (i.e. the overexploitation of the fishery's existing Fish stocks, fish stock), resulting in the species becoming increasingly underpopulated in that area. Overfishing can occur in water bodies of any sizes, such as ponds, wetlands, rivers, lakes or oceans, and can result in resource depletion, reduced biological growth rates and low biomass (ecology), biomass levels. Sustained overfishing can lead to critical depensation, where the fish population is no longer able to sustain itself. Some forms of overfishing, such as the Threatened sharks, overfishing of sharks, has led to the upset of entire marine ecosystems. Types of overfishing include growth overfishing, recruitment overfishing, and ecosystem overfishing. Overfishing not only causes negative impacts on biodiversity and ecosystem functioning, but also reduces fish pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scuba Diving
Scuba diving is a Diving mode, mode of underwater diving whereby divers use Scuba set, breathing equipment that is completely independent of a surface breathing gas supply, and therefore has a limited but variable endurance. The word ''scuba'' is an Acronym#Normal case and acronyms, acronym for "Self-Contained Underwater Breathing Apparatus" and was coined by Christian J. Lambertsen in a patent submitted in 1952. Scuba divers carry their own source of breathing gas, affording them greater independence and movement than surface-supplied divers, and more time underwater than freedivers. Although the use of compressed air is common, other gas blends are also used. Open-circuit scuba systems discharge the breathing gas into the environment as it is exhaled and consist of one or more diving cylinders containing breathing gas at high pressure which is supplied to the diver at ambient pressure through a diving regulator. They may include additional cylinders for range extension, de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hanga Roa
Hanga Roa (; ) (Rapanui language: ''Long bay'') is the main town, harbour, and seat of Easter Island, a municipality of Chile. It is located in the southern part of the island's west coast, in the lowlands between the extinct volcanoes of Terevaka and Rano Kau. History ''Hanga Roa'' in the native Rapa Nui language means "wide bay" or "long bay". Upon Chile's claim of the island, the Rapa Nui were forced in Hanga Roa, and the rest of the land was leased to a sheep farm.Annie MurphyFor Chile, Colossal Trouble On Easter Island ''Npr.org'', 9 September 2010 (accessed on 31 May 2019) For much of the twentieth century, the rest of the island was leased to the Compañía Explotadora de la Isla de Pascua (CEDIP) (a subsidiary of Williamson-Balfour Company) and closed to the Rapa Nui. Some disagreements between the government of Chile and the Rapa Nui have led the locals with ancestral roots to "take over" many hotels in the city. For the locals, it is a way to draw the line between ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rapa Nui Language
Rapa Nui or Rapanui (, Rapa Nui: , Spanish: ), also known as Pascuan () or ''Pascuense'', is an Eastern Polynesian language of the Austronesian language family. It is spoken on Easter Island, also known as ''Rapa Nui''. The island is home to a population of just under 6,000 and is a special territory of Chile. According to census data, there are 9,399 people (on both the island and the Chilean mainland) who identify as ethnically Rapa Nui. Census data does not exist on the primary known and spoken languages among these people. In 2008, the number of fluent speakers was reported as low as 800. Rapa Nui is a minority language and many of its adult speakers also speak Spanish. Most Rapa Nui children now grow up speaking Spanish and those who do learn Rapa Nui begin learning it later in life. History The Rapa Nui language is isolated within Eastern Polynesian, which also includes the Marquesic and Tahitic languages. Within Eastern Polynesian, it is closest to Marquesan morphol ...

Seabird
Seabirds (also known as marine birds) are birds that are adaptation, adapted to life within the marine ecosystem, marine environment. While seabirds vary greatly in lifestyle, behaviour and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding ecological niche, niches have resulted in similar adaptations. The first seabirds evolved in the Cretaceous geological period, period, while modern seabird families emerged in the Paleogene. Seabirds generally live longer, Reproduction, breed later and have fewer young than other birds, but they invest a great deal of time in their young. Most species nest in Bird colony, colonies, varying in size from a few dozen birds to millions. Many species are famous for undertaking long annual bird migration, migrations, crossing the equator or circumnavigating the Earth in some cases. They feed both at the ocean's surface and below it, and even on each other. Seabirds can be highly pelagic, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Height Above Mean Sea Level
Height above mean sea level is a measure of a location's vertical distance (height, elevation or altitude) in reference to a vertical datum based on a historic mean sea level. In geodesy, it is formalized as orthometric height. The zero level varies in different countries due to different reference points and historic measurement periods. Climate change and other forces can cause sea levels and elevations to vary over time. Uses Elevation or altitude above sea level is a standard measurement for: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Mining infrastructure, particularly underground. * Flying objects such as airplanes or helicopters below a Transition Altitude defined by local regulations. Units and abbreviations Elevation or altitude is generally expressed as "metres above mean sea level" in the metric system, or " feet above mean sea level" in United States customary and imperial units.
