Four Corners Monument
The Four Corners Monument marks the quadripoint in the Southwestern United States where the U.S. state, states of Arizona, Colorado, New Mexico, and Utah meet. It is the only point in the United States shared by four states, leading to the area being named the Four Corners region. The monument also marks the boundary between two semi-autonomous Native Americans in the United States, Native American governments, the Navajo Nation, which maintains the monument as a tourist attraction, and the Ute Mountain Ute Tribe Reservation. The origins of the state boundaries marked by the monument occurred just prior to, and during, the American Civil War, when the United States Congress acted to form governments in the area to combat the spread of Slavery in the United States, slavery to the region. When the early territories were formed, their boundaries were designated along Geographic coordinate system, meridian and parallel lines. Beginning in the 1860s, these lines were surveyed and mar ...

Under the law, an enslaved person was treated as property that could be bought, sold, or given away. Slavery lasted in about half of U.S. states until Thirteenth Amendment to the United States Constitution, abolition in 1865, and issues concerning slavery seeped into every aspect of national politics, economics, and social custom.

Autonomy
In developmental psychology and moral, political, and bioethical philosophy, autonomy is the capacity to make an informed, uncoerced decision. Autonomous organizations or institutions are independent or self-governing. Autonomy can also be defined from a human resources perspective, where it denotes a (relatively high) level of discretion granted to an employee in his or her work. In such cases, autonomy is known to generally increase job satisfaction. Self-actualized individuals are thought to operate autonomously of external expectations. In a medical context, respect for a patient's personal autonomy is considered one of many fundamental ethical principles in medicine. Sociology In the sociology of knowledge, a controversy over the boundaries of autonomy inhibited analysis of any concept beyond relative autonomy, until a typology of autonomy was created and developed within science and technology studies. According to it, the institution of science's existing autonom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Colorado Plateau
The Colorado Plateau is a physiographic and desert region of the Intermontane Plateaus, roughly centered on the Four Corners region of the Southwestern United States. This plateau covers an area of 336,700 km2 (130,000 mi2) within western Colorado, northwestern New Mexico, southern and eastern Utah, northern Arizona, and a tiny fraction in the extreme southeast of Nevada. About 90% of the area is drained by the Colorado River and its main tributaries: the Green, San Juan, and Little Colorado. Most of the remainder of the plateau is drained by the Rio Grande and its tributaries. The Colorado Plateau is largely made up of high desert, with scattered areas of forests. In the south-west corner of the Colorado Plateau, nicknamed High Country, lies the Grand Canyon of the Colorado River. Much of the Plateau's landscape is related to the Grand Canyon in both appearance and geologic history. The nickname "Red Rock Country" suggests the brightly colored rock left bare to t ...

Twister (game)
''Twister'' is a game of physical skill produced by Milton Bradley Company and Winning Moves Games USA. It is played on a large plastic mat that is spread on the floor or ground. The mat has four rows of six large colored circles on it with a different color in each row: red, yellow, green and blue. A spinner tells players where they have to place their hand or foot. The game promotes itself as "the game that ties you up in knots". Gameplay A spinner is attached to a square board and is used to determine where the player has to put their hand or foot. The spinner is divided into four labeled sections: left foot, right foot, left hand, and right hand. Each of those four sections are divided into the four colors (red, yellow, green, and blue). After spinning, the combination is called (for example: "right hand yellow") and players must move their matching hand or foot to a circle of the correct color. In a two-player game, no two people can have a hand or foot on the same circl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seal (emblem)
A seal is a device for making an impression in Sealing wax, wax, clay, paper, or some other medium, including an Paper embossing, embossment on paper, and is also the impression thus made. The original purpose was to authenticate a document, or to prevent interference with a package or envelope by applying a seal which had to be broken to open the container (hence the modern English verb "to seal", which implies secure closing without an actual wax seal). The seal-making device is also referred to as the seal ''matrix'' or ''die''; the imprint it creates as the seal impression (or, more rarely, the ''sealing''). If the impression is made purely as a relief resulting from the greater pressure on the paper where the high parts of the matrix touch, the seal is known as a ''dry seal''; in other cases ink or another liquid or liquefied medium is used, in another color than the paper. In most traditional forms of dry seal the design on the seal matrix is in Intaglio (sculpture), intag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bronze
Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (including aluminium, manganese, nickel, or zinc) and sometimes non-metals (such as phosphorus) or metalloids (such as arsenic or silicon). These additions produce a range of alloys some of which are harder than copper alone or have other useful properties, such as strength, ductility, or machinability. The archaeological period during which bronze was the hardest metal in widespread use is known as the Bronze Age. The beginning of the Bronze Age in western Eurasia is conventionally dated to the mid-4th millennium BCE (~3500 BCE), and to the early 2nd millennium BCE in China; elsewhere it gradually spread across regions. The Bronze Age was followed by the Iron Age, which started about 1300 BCE and reaching most of Eurasia by about 500 BCE, although bronze continued to be much more widely used than it is in modern times.

Granite
Granite ( ) is a coarse-grained (phanerite, phaneritic) intrusive rock, intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dike (geology), dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF diagram, QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) conta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Border
Borders are generally defined as geography, geographical boundaries, imposed either by features such as oceans and terrain, or by polity, political entities such as governments, sovereign states, federated states, and other administrative division, subnational entities. Political borders can be established through warfare, colonization, or mutual agreements between the political entities that reside in those areas. Some borders—such as most states' internal administrative borders, or inter-state borders within the Schengen Area—are open border, open and completely unguarded. Most external political borders are partially or fully controlled, and may be crossed legally only at designated border checkpoints; adjacent Border control#Border zones, border zones may also be controlled. For the purposes of border control, airports and Port#Seaport, seaports are also classed as borders. Most countries have some form of border control to regulate or limit the movement of people, animals ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
