Area Code 907
Area code 907 is a telephone area code in the North American Numbering Plan (NANP) for the U.S. state of Alaska, except for the small southeastern community of Hyder, which uses area codes 236, 250, and 778 of neighboring Stewart, British Columbia. Despite having telephone service to the contiguous US via a terrestrial line via the town of Juneau since 1937,AT&T (1974) ''Events in Telephone History'' Alaska was not assigned an area code until after the Alaska submarine cable was opened for traffic in 1956. The Alaska numbering plan area (NPA) was assigned the area code 907 and entered service in 1957. The Alaska numbering plan area is geographically the largest of any in the United States. It is the second-largest in the NANP, and on the entire North American continent behind 867, which serves Canada's northern territories. Because the Aleutian Islands of Alaska cross longitude 180, the Anti-Meridian, 907 may be considered to be both the farthest west and the farthest east ...

North American Numbering Plan
The North American Numbering Plan (NANP) is a telephone numbering plan for twenty-five regions in twenty countries, primarily in North America and the Caribbean. This group is historically known as World Zone 1 and has the international calling code ''1''. Some North American countries, most notably Mexico, do not participate in the NANP. The NANP was originally devised in the 1940s by the American Telephone and Telegraph Company (AT&T) for the Bell System and the independent telephone operators in North America. The goal was to unify the diverse local numbering plans that had been established in the preceding decades and prepare the continent for direct-dialing of calls by customers without the involvement of telephone operators. AT&T continued to administer the numbering plan until the breakup of the Bell System, when administration was delegated to the North American Numbering Plan Administrator (NANPA), a service that has been procured from the private sector by the Fede ...

Race (United States Census)
Race and ethnicity in the United States census, defined by the federal Office of Management and Budget (OMB) and the United States Census Bureau, are the Self-concept, self-identified categories of Race and ethnicity in the United States, race or races and ethnicity chosen by residents, with which they most closely identify, and indicate whether they are of Hispanic or Latino (demonym), Latino origin (the only Race and ethnicity in the United States, categories for ethnicity). The racial categories represent a social-political construct for the race or races that respondents consider themselves to be and, "generally reflect a social definition of race recognized in this country." OMB defines the concept of race as outlined for the U.S. census as not "scientific or anthropological" and takes into account "social and cultural characteristics as well as ancestry", using "appropriate scientific methodologies" that are not "primarily biological or genetic in reference." The race cat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Census
A census is the procedure of systematically acquiring, recording and calculating information about the members of a given population. This term is used mostly in connection with national population and housing censuses; other common censuses include censuses of agriculture, traditional culture, business, supplies, and traffic censuses. The United Nations (UN) defines the essential features of population and housing censuses as "individual enumeration, universality within a defined territory, simultaneity and defined periodicity", and recommends that population censuses be taken at least every ten years. UN recommendations also cover census topics to be collected, official definitions, classifications and other useful information to co-ordinate international practices. The UN's Food and Agriculture Organization (FAO), in turn, defines the census of agriculture as "a statistical operation for collecting, processing and disseminating data on the structure of agriculture, covering th ...

Igneous Rock
Igneous rock (derived from the Latin word ''ignis'' meaning fire), or magmatic rock, is one of the three main The three types of rocks, rock types, the others being Sedimentary rock, sedimentary and metamorphic rock, metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava. The magma can be derived from Partial melting, partial melts of existing rocks in either a Terrestrial planet, planet's mantle (geology), mantle or crust (geology), crust. Typically, the melting is caused by one or more of three processes: an increase in temperature, a decrease in pressure, or a change in composition. Solidification into rock occurs either below the surface as intrusive rocks or on the surface as extrusive (geology), extrusive rocks. Igneous rock may form with crystallization to form granular, crystalline rocks, or without crystallization to form Volcanic glass, natural glasses. Igneous rocks occur in a wide range of geological settings: shields, platforms ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanism
Volcanism, vulcanism or volcanicity is the phenomenon of eruption of molten rock (magma) onto the surface of the Earth or a solid-surface planet or moon, where lava, pyroclastics, and volcanic gases erupt through a break in the surface called a vent. It includes all phenomena resulting from and causing magma within the crust or mantle of the body, to rise through the crust and form volcanic rocks on the surface. Magmas, that reach the surface and solidify, form extrusive landforms. Volcanic processes Magma from the mantle or lower crust rises through the crust towards the surface. If magma reaches the surface, its behavior depends on the viscosity of the molten constituent rock. Viscous (thick) magma produces volcanoes characterised by explosive eruptions, while non-viscous (runny) magma produce volcanoes characterised by effusive eruptions pouring large amounts of lava onto the surface. In some cases, rising magma can cool and solidify without reaching the surface. Inste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tundra
In physical geography, tundra () is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. The term ''tundra'' comes through Russian (') from the Kildin Sámi word (') meaning "uplands", "treeless mountain tract". There are three regions and associated types of tundra: Arctic tundra, alpine tundra, and Antarctic tundra. Tundra vegetation is composed of dwarf shrubs, sedges, grasses, mosses, and lichens. Scattered trees grow in some tundra regions. The ecotone (or ecological boundary region) between the tundra and the forest is known as the tree line or timberline. The tundra soil is rich in nitrogen and phosphorus. The soil also contains large amounts of biomass and decomposed biomass that has been stored as methane and carbon dioxide in the permafrost, making the tundra soil a carbon sink. As global warming heats the ecosystem and causes soil thawing, the permafrost carbon cycle accelerates and releases much of these soil-contained g ...

Yukon Delta National Wildlife Refuge
The Yukon Delta National Wildlife Refuge is a United States National Wildlife Refuge covering about in southwestern Alaska. It is the second-largest National Wildlife Refuge in the country, only slightly smaller than the Arctic National Wildlife Refuge. It is a coastal plain extending to the Bering Sea, covering the delta created by the Yukon and Kuskokwim rivers. The delta includes extensive wetlands near sea level that are often inundated by Bering Sea tides. It is bordered on the east by Wood-Tikchik State Park, the largest state park in the United States. The refuge is administered from offices in Bethel. U.S. President Theodore Roosevelt first set aside southwestern Alaska refuge lands in 1909. Other lands were added through the years until December 2, 1980, when President Jimmy Carter signed the Alaska National Interest Lands Conservation Act (ANILCA) into law, which created the Yukon Delta National Wildlife Reserve by consolidating existing refuges and adding additional land ...

Bering Sea
The Bering Sea (, ; rus, Бе́рингово мо́ре, r=Béringovo móre) is a marginal sea of the Northern Pacific Ocean. It forms, along with the Bering Strait, the divide between the two largest landmasses on Earth: Eurasia and The Americas. It comprises a deep water basin, which then rises through a narrow slope into the shallower water above the continental shelf, continental shelves. The Bering Sea is named for Vitus Bering, a Denmark, Danish navigator in Russian service, who, in 1728, was the first European to systematically explore it, sailing from the Pacific Ocean northward to the Arctic Ocean. The Bering Sea is separated from the Gulf of Alaska by the Alaska Peninsula. It covers over and is bordered on the east and northeast by Alaska, on the west by the Russian Far East and the Kamchatka Peninsula, on the south by the Alaska Peninsula and the Aleutian Islands and on the far north by the Bering Strait, which connects the Bering Sea to the Arctic Ocean's Chukchi ...

Etolin Strait
Etolin Strait is a strait of the Pacific Ocean in western Alaska, the United States. Geography The strait connects Kuskokwim Bay and the Bering Sea, at . It is long and 48–80 km (30-50) miles wide. It is known for strong tidal currents. It is between Nunivak Island to its west and Nelson Island and the Alaskan mainland to its east. It is demarcated by Cape Etolin to the northwest and Cape Corwin to the southwest (both on Nunivak Island), by Cape Vancouver on Nelson Island to the northeast, and by Cape Avinol on the Alaskan mainland to the southeast. History Etolin Strait is named after Adolf Etolin, who was the first European to discover it, and originally named it Cook Strait. Etolin was subsequently the colonial governor of Russian America Russian America (russian: Русская Америка, Russkaya Amerika) was the name for the Russian Empire's colonial possessions in North America from 1799 to 1867.

Kinia River
''Melanoleuca'' is a poorly known genus of saprotrophic mushrooms traditionally classified in the family Tricholomataceae. Most are small to medium sized, white, brown, ocher or gray with a cylindrical to subcylindrical stipe and white to pale yellowish gills. The basidiospores are ellipsoid and ornamented with amyloid warts. ''Melanoleuca'' is considered a difficult group to study due to their macroscopic similarities among species and the need of a thorough microscopic analysis to separate species. DNA studies have determined that this genus is closely related to ''Amanita'' and ''Pluteus'' and that it does not belong to the family Tricholomataceae. Etymology The name of the genus is derived from the Ancient Greek ''melano-'' meaning "black", and ''leukos'' meaning "white". Description General As a genus ''Melanoleuca'' is quite distinctive, and it is not very hard to recognize a mushroom which belongs to it on sight. However the identification of its individual species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
