Norbeck, Maryland
Norbeck is the area of Montgomery County, Maryland, United States, around Norbeck Road ( Maryland Route 28) east of Georgia Avenue to Layhill Road. Shortly before the Civil War, free blacks founded Norbeck. History The Sandy Spring Museum describes Norbeck as:Southwestern outpost of the greater Sandy Spring neighborhood ndput down roots as a free-black community shortly before the Civil War. With emancipation, it grew with the largest population concentrated in a community known as Mt. Pleasant between present Georgia Avenue and Muncaster Mill Road. In Mt. Pleasant were a church, school, and meeting hall, along with a store run by whites. White families, too, settled along the area's intersecting roads. Unlike most Sandy Spring crossroads, Norbeck was slow to sprout the usual general store and blacksmith/wheelwright shops. Not until the 1880s did a store and post office open, and another decade elapsed before a smith set up shop. By 1900 A.E. Stonestreet was operating his la ...

List Of Sovereign States
The following is a list providing an overview of sovereign states around the world with information on their status and recognition of their sovereignty. The 205 listed states can be divided into three categories based on membership within the United Nations System: 193 member states of the United Nations, UN member states, two United Nations General Assembly observers#Current non-member observers, UN General Assembly non-member observer states, and ten other states.

Wheelwright
A wheelwright is a Artisan, craftsman who builds or repairs wooden wheels. The word is the combination of "wheel" and the word "wright" (which comes from the Old English word "''wryhta''", meaning a worker - as also in shipbuilding, shipwright and arkwright). This occupational name became the English surname ''Wright'', and also appears in surnames like ''Cartwright'' and ''Wainwright''. These tradesmen made wheels for carts (cartwheels), wagons (wains), traps and coaches. They also made the wheels, and often the frames, for spinning wheels, and the belt drives of steam powered machinery. First constructing the hub (called the nave), the spokes and the rim segments called felloes, and assembling them all into a unit working from the center of the wheel outwards. Most wheels were made from wood, but other materials have been used, such as bone and horn (anatomy), horn, for decorative or other purposes. Some earlier construction for wheels such as those used in early chariots wer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pluton
In geology, an igneous intrusion (or intrusive body or simply intrusion) is a body of intrusive igneous rock that forms by crystallization of magma slowly cooling below the surface of the Earth. Intrusions have a wide variety of forms and compositions, illustrated by examples like the Palisades Sill of New York and New Jersey; the Henry Mountains of Utah; the Bushveld Igneous Complex of South Africa; Shiprock in New Mexico; the Ardnamurchan intrusion in Scotland; and the Sierra Nevada Batholith of California. Because the solid country rock into which magma intrudes is an excellent insulator, cooling of the magma is extremely slow, and intrusive igneous rock is coarse-grained ( phaneritic). Intrusive igneous rocks are classified separately from extrusive igneous rocks, generally on the basis of their mineral content. The relative amounts of quartz, alkali feldspar, plagioclase, and feldspathoid is particularly important in classifying intrusive igneous rocks. Intru ...

Ordovician
The Ordovician ( ) is a geologic period and System (geology), system, the second of six periods of the Paleozoic Era (geology), Era, and the second of twelve periods of the Phanerozoic Eon (geology), Eon. The Ordovician spans 41.6 million years from the end of the Cambrian Period Megaannum, Ma (million years ago) to the start of the Silurian Period Ma. The Ordovician, named after the Celtic Britons, Welsh tribe of the Ordovices, was defined by Charles Lapworth in 1879 to resolve a dispute between followers of Adam Sedgwick and Roderick Murchison, who were placing the same Rock (geology), rock beds in North Wales in the Cambrian and Silurian systems, respectively. Lapworth recognized that the fossil fauna in the disputed Stratum, strata were different from those of either the Cambrian or the Silurian systems, and placed them in a system of their own. The Ordovician received international approval in 1960 (forty years after Lapworth's death), when it was adopted as an official per ...

Commercial Development
Commerce is the organized system of activities, functions, procedures and institutions that directly or indirectly contribute to the smooth, unhindered large-scale exchange (distribution through transactional processes) of goods, services, and other things of value at the right time, place, quantity, quality and price through various channels among the original producers and the final consumers within local, regional, national or international economies. The diversity in the distribution of natural resources, differences of human needs and wants, and division of labour along with comparative advantage are the principal factors that give rise to commercial exchanges. Commerce consists of trade and aids to trade (i.e. auxiliary commercial services) taking place along the entire supply chain. Trade is the exchange of goods (including raw materials, intermediate and finished goods) and services between buyers and sellers in return for an agreed-upon price at traditional (or o ...

Tree
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller palms, tree ferns, bananas, and bamboos. Trees are not a monophyletic taxonomic group but consist of a wide variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are around three trillion mature trees in the world currently. A tree typically has many secondary branches supported cle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woodland
A woodland () is, in the broad sense, land covered with woody plants (trees and shrubs), or in a narrow sense, synonymous with wood (or in the U.S., the '' plurale tantum'' woods), a low-density forest forming open habitats with plenty of sunlight and limited shade (see differences between British, American and Australian English explained below). Some savannas may also be woodlands, such as ''savanna woodland'', where trees and shrubs form a light canopy. Woodlands may support an understory of shrubs and herbaceous plants including grasses. Woodland may form a transition to shrubland under drier conditions or during early stages of primary or secondary succession. Higher-density areas of trees with a largely closed canopy that provides extensive and nearly continuous shade are often referred to as forests. Extensive efforts by conservationist groups have been made to preserve woodlands from urbanization and agriculture. For example, the woodlands of Northwest Indiana ha ...

Suburb
A suburb (more broadly suburban area) is an area within a metropolitan area. They are oftentimes where most of a metropolitan areas jobs are located with some being predominantly residential. They can either be denser or less densely populated than the city and can have a higher or lower rate of detached single family homes than the city as well. Suburbs can have their own political or legal jurisdictions, especially in the United States, but this is not always the case, especially in the United Kingdom, where most suburbs are located within the administrative boundaries of cities. In most English-speaking world, English-speaking countries, suburban areas are defined in contrast to core city, central city or inner city areas, but in Australian English and South African English, ''suburb'' has become largely synonymous with what is called a "neighborhood" in the U.S. Due in part to historical trends such as white flight, some suburbs in the United States have a higher population ...
