Birdwatching
Birdwatching, or birding, is the observing of birds, either as a recreational activity or as a form of citizen science. A birdwatcher may observe by using their naked eye, by using a visual enhancement device such as binoculars or a telescope, by listening for bird sounds, watching public webcams, or by viewing smart bird feeder cameras. Most birdwatchers pursue this activity for recreational or social reasons, unlike ornithologists, who engage in the study of birds using formal scientific methods. Birding, birdwatching, and twitching The first recorded use of the term ''birdwatcher'' was in 1712 by William Oldsworth. The term ''birding'' was also used for the practice of ''fowling'' or hunting with firearms as in Shakespeare's '' The Merry Wives of Windsor'' (1602): "She laments sir... her husband goes this morning a-birding." The terms ''birding'' and ''birdwatching'' are today used by some interchangeably, although some participants prefer ''birding'', partly because ...

Coal-fired Power Stations In Tennessee
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat which is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous (Pennsylvanian) and Permian times. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some iron and steel-making and other industrial processes burn coal. The extraction and b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Towers Completed In 1976
A tower is a tall structure, taller than it is wide, often by a significant factor. Towers are distinguished from masts by their lack of guy-wires and are therefore, along with tall buildings, self-supporting structures. Towers are specifically distinguished from buildings in that they are built not to be habitable but to serve other functions using the height of the tower. For example, the height of a clock tower improves the visibility of the clock, and the height of a tower in a fortified building such as a castle increases the visibility of the surroundings for defensive purposes. Towers may also be built for observation, leisure, or telecommunication purposes. A tower can stand alone or be supported by adjacent buildings, or it may be a feature on top of a larger structure or building. Etymology Old English ''torr'' is from Latin ''turris'' via Old French ''tor''. The Latin term together with Greek τύρσις was loaned from a pre-Indo-European Mediterranean language, ...

Energy Infrastructure Completed In 1955
Energy () is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, the internal energy contained within a thermodynamic system, and rest energy associated with an object's rest mass. These are not mutually exclusive. All living organisms constantly take in and release energy. The Earth's climate and ecosystems processes are driven primaril ...

Knoxville News Sentinel
The ''Knoxville News Sentinel'', also known as ''Knox News'', is a daily newspaper in Knoxville, Tennessee, United States, owned by the Gannett Company. History The newspaper was formed in 1926 from the merger of two competing newspapers: ''The Knoxville News'' and ''The Knoxville Sentinel''. John Trevis Hearn began publishing ''The Sentinel'' in December 1886, while ''The News'' was started in 1921 by Robert P. Scripps and Roy W. Howard. The two merged in 1926 under Scripps-Howard ownership, with the first edition of ''The Knoxville News-Sentinel'' appearing on November 22 of that year. The editor from 1921 to 1931, Edward J. Meeman, later was sent to Memphis to edit the since defunct '' Memphis Press-Scimitar''. In 1986, the ''News-Sentinel'' became a morning paper, with the other paper in Knoxville, the '' Knoxville Journal'', becoming an evening paper. The ''Journal'' ceased publication as a daily in 1991, when the joint operating agreement between the two papers exp ...

List Of Power Stations In Tennessee
The U.S. state of Tennessee receives its power from a variety of sources. The Tennessee Valley Authority (TVA) is the primary utility in Tennessee which generates electricity and sells it to hundreds of local utilities and industrial customers. Like most of the US, the sources used to generate power in Tennessee have changed substantially in the last decade. Coal's share of power has declined from nearly 60% in 2008 to about 25% in 2018, while natural gas has increased significantly. Tennessee is home to the two newest nuclear reactors in the US at Watts Bar Nuclear Plant, unit 2 being the first to begin operation in the 21st century. After Watts Bar Unit 2 began operation in late 2016, nuclear power passed coal as the top source of electricity. In November 2018 natural gas produced more power than coal for the first time in Tennessee. Tennessee is home to the third largest pumped-storage hydroelectric facility in the US, and has the third highest net generation of hydroelectric ...

Tennessee River
The Tennessee River is a long river located in the Southern United States, southeastern United States in the Tennessee Valley. Flowing through the states of Tennessee, Alabama, Mississippi, and Kentucky, it begins at the confluence of French Broad River, French Broad and Holston River, Holston rivers at Knoxville, Tennessee, Knoxville, and drains into the Ohio River near Paducah, Kentucky. It is the largest tributary of the Ohio, and drains a basin of . Its tributary, the Little Tennessee River, flows into it from Western North Carolina and northeastern Georgia. Etymology The river appears on France, French maps from the late 17th century with the names "Caquinampo" or "Kasqui." Maps from the early 18th century call it "Cussate," "Mitchell Map, Hogohegee," "Callamaco," and "Acanseapi." A 1755 British map showed the Tennessee River as the "River of the Cherakees."Ann ToplovichTennessee River System, ''Tennessee Encyclopedia of History and Culture'', December 25, 2009; upd ...

Clinch River
The Clinch River is a river that flows southwest for more than through the Great Appalachian Valley in the U.S. states of Virginia and Tennessee, gathering various tributaries, including the Powell River, before joining the Tennessee River in Kingston, Tennessee. Course The Clinch River is dammed twice: by Norris Dam, the first dam built by the Tennessee Valley Authority (TVA); and by the Melton Hill Dam, the only TVA dam with a navigation lock that is not located on the main channel of the Tennessee River. An important tributary of the Clinch River is the Powell River. The Clinch and Powell drainage basins are separated by Powell Mountain. Tributaries entering the Clinch River below Norris Dam but above Melton Hill Dam include Coal Creek, Hinds Creek, Bull Run Creek, and Beaver Creek. Poplar Creek enters the river below the Melton Hill Dam. History A peninsula located at the mouth of the Clinch River, later called Southwest Point, was important to generations of N ...

Emory River
The Emory River is a river draining a portion of Tennessee's Cumberland Plateau. It flows for just over from its source near Frozen Head State Park to its mouth along the Clinch River at Kingston, Tennessee. Hydrography The Emory River rises on the slopes of Fork Mountain and descends through a valley along the northern base of Bird Mountain, a prominent ridge in Frozen Head State Park in Morgan County. The surrounding area has been the subject of extensive strip mining for coal which has resulted in some stream pollution. The stream initially flows basically westward and is crossed by U.S. Highway 27. Turning more southwestward, it is paralleled for a time by a line of the Norfolk Southern Railway. It meets the Obed River in the southeast corner of the expansive Catoosa Wildlife Management Area, a large game-management area operated by the Tennessee Wildlife Resources Agency. Still paralleled by the railroad, the stream crosses into Roane County near Harriman. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Fly Ash
Coal combustion products (CCPs), also called coal combustion wastes (CCWs) or coal combustion residuals (CCRs), are byproducts of burning coal. They are categorized in four groups, each based on physical and chemical forms derived from coal combustion methods and emission controls: * Fly ash is captured after coal combustion by filters (Dust collector#Fabric filters, bag houses), electrostatic precipitators and other air pollution control devices. It comprises 60 percent of all coal combustion waste (labeled here as coal combustion products). It is most commonly used as a high-performance substitute for Portland cement or as Cement clinker, clinker for Portland cement production. Cements blended with fly ash are becoming more common. Building material applications range from grouts and masonry products to cellular concrete and roofing tiles. Many asphaltic concrete pavements contain fly ash. Geotechnical applications include soil stabilization, road base, structural fill, embankmen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
