Rotorua Lakes
Rotorua Lakes District or Rotorua District is a territorial authority district in the North Island of New Zealand. It has one urban area of significant size, the city of Rotorua. The district is governed by Rotorua Lakes Council, which is headquartered in Rotorua and is headed by a mayor. The district falls within two regional council areas, with the majority of the area and Rotorua city in the Bay of Plenty region and the rest in the Waikato region. Tania Tapsell has been the mayor of Rotorua since the 2022 local elections. History Rotorua has an unusual history as the town was built by the Government as a tourist destination in the 1880s. Through the Rotorua Borough Act 1922, which achieved royal assent on 28 September 1922, the Rotorua Borough was formed. The inaugural elections for mayor were held in February 1923 and Cecil Clinkard was successful. In 1962, Rotorua was proclaimed a city. In 1979, the status was changed to a district when Rotorua City and Rotorua County amal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magma Chamber
A magma chamber is a large pool of liquid rock beneath the surface of the Earth. The molten rock, or magma, in such a chamber is less dense than the surrounding country rock, which produces buoyant forces on the magma that tend to drive it upwards. If the magma finds a path to the surface, then the result will be a volcanic eruption; consequently, many volcanoes are situated over magma chambers. These chambers are hard to detect deep within the Earth, and therefore most of those known are close to the surface, commonly between 1 km and 10 km down. Dynamics of magma chambers Magma rises through cracks from beneath and across the crust because it is less dense than the surrounding rock. When the magma cannot find a path upwards it pools into a magma chamber. These chambers are commonly built up over time, by successive horizontal or vertical magma injections. Influx of new magma causes reaction of pre-existing crystals and the pressure in the chamber to increase. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maketu
Maketu is a small town on the Bay of Plenty Coast in New Zealand. Maketu is located in the Western Bay of Plenty, New Zealand. Maketu has an estuary from which the Kaituna River used to flow. It is also adjacent to Newdicks Beach located on the south eastern side of Okurei Point. Maketu is rich in ancestral Māori culture, specifically the Te Arawa tribe. Maketu was the landing site of the Te Arawa canoe. The Chief who led the voyage of the Te Arawa waka from Hawaiki to New Zealand/Aotearoa was known as Tametekapua. Many Māori settled in Maketu, but some continued their journey inland, using the Kaituna River as far as Rotorua. Maketu is named after an ancient kūmara ( sweet potato) pit in Hawaiki, the Māori ancestral homeland. Maketu has a predominantly Māori population, although in recent years there has been an influx of many cultures to Maketu. In 2011, Maketu was one of many areas along the Bay of Plenty Coast affected by the grounding of the MV Rena and the subsequ ...

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Kaituna River
The Kaituna River is in the Bay of Plenty region of the North Island of New Zealand. It is the outflow from Lakes Lake Rotorua, Rotorua and Lake Rotoiti (Bay of Plenty), Rotoiti, and flows northwards for , emptying into the Bay of Plenty near Te Puke. It was the subject of a claim concerning the effluent flowing down the river from Lake Rotorua, which resulted in movement to a land treatment system. The New Zealand Ministry for Culture and Heritage gives a translation of "eat eels" for ''Kaituna''. The upper section of the Kaituna, also referred to as Okere River, offers some of the best whitewater kayaking and rafting in the world, with the Okere Falls area containing the highest commercially rafted waterfall, , in the world. It is also famous for its trout fishing. Cultural claim During the 1970s Lake Rotorua was becoming eutrophication, eutrophic under heavy nutrient loadings, leading the New Zealand Ministry of Works, Ministry of Works to propose diverting some sewage flow ...

Lake Rotoiti, Bay Of Plenty
Lake Rotoiti is a lake in the Bay of Plenty region of New Zealand. It is the northwesternmost in a chain of lakes formed within the Okataina Caldera. The lake is close to the northern shore of its more famous neighbour, Lake Rotorua, and is connected to it via the Ohau Channel. It drains to the Kaituna River, which flows into the Bay of Plenty near Maketu. The full name of the lake is Te Rotoiti-kite-a-Īhenga, which in the Māori language means "The Small Lake Discovered By Īhenga", the Māori explorer also credited with discovering Lake Rotorua. Legend says that the lake was named as such because when Ihenga first saw it, he was only able to see a small part of it and thought the lake was a lot smaller. Since the 1960s, the quality of lake water has been negatively affected by inflows of nitrogen rich water from Lake Rotorua, agricultural run-off from surrounding farms and seepage from domestic septic tanks. The effects of this included an almost permanent algal bloom in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sulfur
Sulfur (or sulphur in British English) is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Elemental sulfur is a bright yellow, crystalline solid at room temperature. Sulfur is the tenth most abundant element by mass in the universe and the fifth most on Earth. Though sometimes found in pure, native form, sulfur on Earth usually occurs as sulfide and sulfate minerals. Being abundant in native form, sulfur was known in ancient times, being mentioned for its uses in ancient India, ancient Greece, China, and ancient Egypt. Historically and in literature sulfur is also called brimstone, which means "burning stone". Today, almost all elemental sulfur is produced as a byproduct of removing sulfur-containing contaminants from natural gas and petroleum.. Downloahere The greatest commercial use of the element is the production o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geyser
A geyser (, ) is a spring characterized by an intermittent discharge of water ejected turbulently and accompanied by steam. As a fairly rare phenomenon, the formation of geysers is due to particular hydrogeological conditions that exist only in a few places on Earth. Generally all geyser field sites are located near active volcanic areas, and the geyser effect is due to the proximity of magma. Generally, surface water works its way down to an average depth of around where it contacts hot rocks. The resultant boiling of the pressurized water results in the geyser effect of hot water and steam spraying out of the geyser's surface vent (a hydrothermal explosion). A geyser's eruptive activity may change or cease due to ongoing mineral deposition within the geyser plumbing, exchange of functions with nearby hot springs, earthquake influences, and human intervention. Like many other natural phenomena, geysers are not unique to Earth. Jet-like eruptions, often referred to as cryoge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geothermal (geology)
Geothermal gradient is the rate of temperature change with respect to increasing depth in Earth's interior. As a general rule, the crust temperature rises with depth due to the heat flow from the much hotter mantle; away from tectonic plate boundaries, temperature rises in about 25–30 °C/km (72–87 °F/mi) of depth near the surface in most of the world. However, in some cases the temperature may drop with increasing depth, especially near the surface, a phenomenon known as ''inverse'' or ''negative'' geothermal gradient. The effects of weather, sun, and season only reach a depth of approximately 10-20 metres. Strictly speaking, ''geo''-thermal necessarily refers to Earth but the concept may be applied to other planets. In SI units, the geothermal gradient is expressed as °C/km, K/km, or mK/m. These are all equivalent. Earth's internal heat comes from a combination of residual heat from planetary accretion, heat produced through radioactive decay, latent hea ...
