List Of Kentucky Cities
Kentucky, a U.S. state, state in the United States, has 418 active cities. Kentucky cities are divided into two classes, which define their form of local government: first class and home rule. First class cities are permitted to operate only under the mayor–council government, mayor-council, while home rule cities may operate under the mayor-council, City commission government, city commission, and city manager forms. Currently, Louisville, Kentucky, Louisville is Kentucky's only designated "first class" city. However, by virtue of also having Consolidated city-county, merged city-county governments, both Louisville and Lexington, Kentucky, Lexington are treated as special cases under state law, and were permitted to retain their existing local forms of government and powers. Classes The two-class system went into effect on January 1, 2015, following the 2014 passage of Kentucky House of Representatives, House Bill 331 by the Kentucky General Assembly and the bill's signin ...

Louisville And Nashville Railroad
The Louisville and Nashville Railroad , commonly called the L&N, was a Class I railroad that operated freight and passenger services in the southeast United States. Chartered by the Commonwealth of Kentucky in 1850, the road grew into one of the great success stories of American business. Operating under one name continuously for 132 years, it survived civil war and economic depression and several waves of social and technological change. Under Milton H. Smith, president of the company for 30 years, the L&N grew from a road with less than of track to a system serving fourteen states. As one of the premier Southern railroads, the L&N extended its reach far beyond its namesake cities, stretching to St. Louis, Memphis, Atlanta, and New Orleans. The railroad was economically strong throughout its lifetime, operating freight and passenger trains in a manner that earned it the nickname, "The Old Reliable". Growth of the railroad continued until its purchase and the tumultuous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AMSL
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.

Hardiness Zone
A hardiness zone is a geographic area defined as having a certain average annual minimum temperature, a factor relevant to the survival of many plants. In some systems other statistics are included in the calculations. The original and most widely used system, developed by the United States Department of Agriculture (USDA) as a rough guide for landscaping and gardening, defines 13 zones by long-term average annual extreme minimum temperatures. It has been adapted by and to other countries (such as Canada) in various forms. A plant may be described as "hardy to zone 10": this means that the plant can withstand a minimum temperature of . Unless otherwise specified, in American contexts "hardiness zone" or simply "zone" usually refers to the USDA scale. However, some confusion can exist in discussing buildings and HVAC, where "climate zone" can refer to the International Energy Conservation Code zones, where Zone 1 is warm and Zone 8 is cold. Other hardiness rating schemes have been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Humid Subtropical Climate
A humid subtropical climate is a subtropical -temperate climate type, characterized by long and hot summers, and cool to mild winters. These climates normally lie on the southeast side of all continents (except Antarctica), generally between latitudes 25° and 40° and are located poleward from adjacent tropical climates, and equatorward from either humid continental (in North America and Asia) or oceanic climates (in other continents). It is also known as warm temperate climate in some climate classifications. Under the Köppen climate classification, ''Cfa'' and ''Cwa'' climates are either described as humid subtropical climates or warm temperate climates. This climate features mean temperature in the coldest month between (or ) and and mean temperature in the warmest month or higher. However, while some climatologists have opted to describe this climate type as a "humid subtropical climate", Köppen himself never used this term. The humid subtropical climate classific ...

Köppen Climate Classification
The Köppen climate classification divides Earth climates into five main climate groups, with each group being divided based on patterns of seasonal precipitation and temperature. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indicates a tropical rainforest climate. The system assigns a temperature subgroup for all groups other than those in the ''A'' group, indicated by the third letter for climates in ''B'', ''C'', ''D'', and the second letter for climates in ''E''. Other examples include: ''Cfb'' indicating an oceanic climate with warm summers as indicated by the ending ''b.'', while ''Dwb'' indicates a semi-Monsoon continental climate, monsoonal continental climate ...

Meandering River
A meander is one of a series of regular sinuous curves in the channel of a river or other watercourse. It is produced as a watercourse erodes the sediments of an outer, concave bank ( cut bank or river cliff) and deposits sediments on an inner, convex bank which is typically a point bar. The result of this coupled erosion and sedimentation is the formation of a sinuous course as the channel migrates back and forth across the axis of a floodplain. The zone within which a meandering stream periodically shifts its channel is known as a meander belt. It typically ranges from 15 to 18 times the width of the channel. Over time, meanders migrate downstream, sometimes in such a short time as to create civil engineering challenges for local municipalities attempting to maintain stable roads and bridges.Neuendorf, K.K.E., J.P. Mehl Jr., and J.A. Jackson, J.A., eds. (2005) ''Glossary of Geology'' (5th ed.). Alexandria, Virginia, American Geological Institute. 779 pp. Charlton, R., 2007 ...

Kentucky River
The Kentucky River is a tributary of the Ohio River in Kentucky, United States. The river and its tributaries drain much of eastern and central Kentucky, passing through the Eastern Coalfield, the Cumberland Mountains, and the Bluegrass region.U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map , accessed June 13, 2011 Its watershed encompasses about , and it supplies drinking water to about one-sixth of the population of the state. The river is no longer navigable above Lock 4 at Frankfort, as concrete bulkheads have been poured behind the upper lock gates of Locks 5–14 to strengthen the dam structures. All fourteen dams are managed by the state-run Kentucky River Authority. The primary importance of the locks today is to maintain a pool that allows the city of Lexington to draw its drinking water from the river. Although the Lexington area receives well over of precipitation annually, the limestone karst geology of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Appalachian Mountains
The Appalachian Mountains, often called the Appalachians, are a mountain range in eastern to northeastern North America. The term "Appalachian" refers to several different regions associated with the mountain range, and its surrounding terrain. The general definition used is one followed by the United States Geological Survey and the Geological Survey of Canada to describe the respective countries' Physiographic region, physiographic regions. The U.S. uses the term Appalachian Highlands and Canada uses the term Appalachian Uplands; the Appalachian Mountains are not synonymous with the Appalachian Plateau, which is one of the provinces of the Appalachian Highlands. The Appalachian range runs from the Newfoundland (island), Island of Newfoundland in Canada, southwestward to Central Alabama in the United States; south of Newfoundland, it crosses the 96-square-mile (248.6 km2) archipelago of Saint Pierre and Miquelon, an overseas collectivity of France, meaning it is technica ...

Cumberland Plateau
The Cumberland Plateau is the southern part of the Appalachian Plateau in the Appalachian Mountains of the United States. It includes much of eastern Kentucky and Tennessee, and portions of northern Alabama and northwest Georgia. The terms " Allegheny Plateau" and the "Cumberland Plateau" both refer to the dissected plateau lands lying west of the main Appalachian Mountains. The terms stem from historical usage rather than geological difference, so there is no strict dividing line between the two. Two major rivers share the names of the plateaus, with the Allegheny River rising in the Allegheny Plateau and the Cumberland River rising in the Cumberland Plateau in Harlan County, Kentucky. Geography The Cumberland Plateau is a deeply dissected plateau, with topographic relief commonly of about , and frequent sandstone outcroppings and bluffs. At Kentucky's Pottsville Escarpment, which is the transition from the Cumberland Plateau to the Bluegrass in the north and the Penny ...
