Smith Island Cake
Smith Island is a collection of three distinct island communities, Tylerton, Rhodes Point, and Ewell, Maryland on the Chesapeake Bay, on the border of Maryland and Virginia territorial waters in the United States. The island is the last inhabited island in Maryland that is not accessible by vehicle, where most of the islands are eroding due to tidal currents and sea level rise. Smith Island is expected to completely erode by 2100. The island's population is approximately 220, down from a peak of about 800. On its Maryland side, Smith Island is a census-designated place (CDP) in Somerset County. It is included in the Salisbury, Maryland-Delaware Metropolitan Statistical Area. Geography Smith Island lies approximately west of Crisfield, Maryland, across the Tangier Sound portion of the Chesapeake Bay. The island consists of three communities, namely Ewell, Tylerton and Rhodes Point, which all sit on the Maryland portion of the island. The Virginia portion is uninhabited, alth ...

Census-designated Place
A census-designated place (CDP) is a concentration of population defined by the United States Census Bureau for statistical purposes only. CDPs have been used in each decennial census since 1980 as the counterparts of incorporated places, such as self-governing cities, towns, and villages, for the purposes of gathering and correlating statistical data. CDPs are populated areas that generally include one officially designated but currently unincorporated community, for which the CDP is named, plus surrounding inhabited countryside of varying dimensions and, occasionally, other, smaller unincorporated communities as well. CDPs include small rural communities, edge cities, colonias located along the Mexico–United States border, and unincorporated resort and retirement communities and their environs. The boundaries of any CDP may change from decade to decade, and the Census Bureau may de-establish a CDP after a period of study, then re-establish it some decades later. Most unin ...

English American
English Americans (historically known as Anglo-Americans) are Americans whose ancestry originates wholly or partly in England. In the 2020 American Community Survey, 25.21 million self-identified as being of English origin. The term is distinct from British Americans, which includes not only English Americans but also Scottish, Scotch-Irish (descendents of Ulster Scots from Ulster, Ireland), Welsh, Cornish and Manx Americans from the whole of the United Kingdom. Demographers regard the reported number of English Americans as a serious undercount, as the index of inconsistency is high and many if not most Americans of English ancestry have a tendency to identify simply as "Americans" or if of mixed European ancestry, identify with a more recent and differentiated ethnic group. In the 1980 census, 49.6 million Americans claimed English ancestry. At 26.34%, this was the largest group amongst the 188 million people who reported at least one ancestry. The population was 226 mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

African American (U
African Americans (also referred to as Black Americans and Afro-Americans) are an ethnic group consisting of Americans with partial or total ancestry from sub-Saharan Africa. The term "African American" generally denotes descendants of enslaved Africans who are from the United States. While some Black immigrants or their children may also come to identify as African-American, the majority of first generation immigrants do not, preferring to identify with their nation of origin. African Americans constitute the second largest racial group in the U.S. after White Americans, as well as the third largest ethnic group after Hispanic and Latino Americans. Most African Americans are descendants of enslaved people within the boundaries of the present United States. On average, African Americans are of West/ Central African with some European descent; some also have Native American and other ancestry. According to U.S. Census Bureau data, African immigrants generally do not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White (U
White is the lightest color and is achromatic (having no hue). It is the color of objects such as snow, chalk, and milk, and is the opposite of black. White objects fully reflect and scatter all the visible wavelengths of light. White on television and computer screens is created by a mixture of red, blue, and green light. The color white can be given with white pigments, especially titanium dioxide. In ancient Egypt and ancient Rome, priestesses wore white as a symbol of purity, and Romans wore white togas as symbols of citizenship. In the Middle Ages and Renaissance a white unicorn symbolized chastity, and a white lamb sacrifice and purity. It was the royal color of the kings of France, and of the monarchist movement that opposed the Bolsheviks during the Russian Civil War (1917–1922). Greek and Roman temples were faced with white marble, and beginning in the 18th century, with the advent of neoclassical architecture, white became the most common color of new churches ...

Population Density
Population density (in agriculture: standing stock or plant density) is a measurement of population per unit land area. It is mostly applied to humans, but sometimes to other living organisms too. It is a key geographical term.Matt RosenberPopulation Density Geography.about.com. March 2, 2011. Retrieved on December 10, 2011. In simple terms, population density refers to the number of people living in an area per square kilometre, or other unit of land area. Biological population densities Population density is population divided by total land area, sometimes including seas and oceans, as appropriate. Low densities may cause an extinction vortex and further reduce fertility. This is called the Allee effect after the scientist who identified it. Examples of the causes of reduced fertility in low population densities are * Increased problems with locating sexual mates * Increased inbreeding Human densities Population density is the number of people per unit of area, usuall ...

2010 United States Census
The United States census of 2010 was the twenty-third United States national census. National Census Day, the reference day used for the census, was April 1, 2010. The census was taken via mail-in citizen self-reporting, with enumerators serving to spot-check randomly selected neighborhoods and communities. As part of a drive to increase the count's accuracy, 635,000 temporary enumerators were hired. The population of the United States was counted as 308,745,538, a 9.7% increase from the 2000 census. This was the first census in which all states recorded a population of over half a million people as well as the first in which all 100 largest cities recorded populations of over 200,000. Introduction As required by the United States Constitution, the U.S. census has been conducted every 10 years since 1790. The 2000 U.S. census was the previous census completed. Participation in the U.S. census is required by law of persons living in the United States in Title 13 of the United ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Accomack County, Virginia
Accomack County is a United States county located in the eastern edge of the Commonwealth of Virginia. Together, Accomack and Northampton counties make up the Eastern Shore of Virginia, which in turn is part of the Delmarva Peninsula, bordered by the Chesapeake Bay and the Atlantic Ocean. The Accomack county seat is the town of Accomac. The Eastern Shore of Virginia was known as "Accomac Shire," until it was renamed Northampton County in 1642. The present Accomack County was created from Northampton County in 1663. The county and the original shire were named for the Accawmack Indians, who resided in the area when the English first explored it in 1603. As of the 2020 census, the total population was 33,413 people. The population of Accomack has remained relatively stable over the last century, though Accomack is one of the poorest parts of Virginia. History The county was named for its original residents, the Accomac people, an Eastern Algonquian-speaking Native American tr ...

Martin National Wildlife Refuge
Glenn Martin National Wildlife Refuge includes the northern half of Smith Island (in Somerset County, Maryland), which lies west of Crisfield, Maryland, and Watts Island (in Accomack County, Virginia), which is located between the eastern shore of Virginia and Tangier Island. Both islands are situated in the lower Chesapeake Bay. The refuge was established in 1954 when the late Glenn L. Martin donated to the U.S. Fish and Wildlife Service. Since then, donation and purchase has increased the size of the refuge to . The tidal marsh, coves and creeks, and vegetated ridges of the refuge form an important stopover and wintering area for thousands of migratory waterfowl and nesting habitat for various wildlife species. Martin National Wildlife Refuge is the largest unit of the Chesapeake Islands Refuges, which also includes Spring Island, Barren Island, and Bishops Head in Dorchester County, Maryland. The management of the Chesapeake Islands Refuges falls under the umbrella of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coastal Management
Coastal management is defence against flooding and erosion, and techniques that stop erosion to claim lands. Protection against rising sea levels in the 21st century is crucial, as sea level rise accelerates due to climate change. Changes in sea level damage beaches and coastal systems are expected to rise at an increasing rate, causing coastal sediments to be disturbed by tidal energy. Coastal zones occupy less than 15% of the Earth's land area, while they host more than 40% of the world population. Nearly 1.2 billion people live within 100 km of shoreline and 100 m of sea level, with an average density 3 times higher than the global average for population. With three-quarters of the world population expected to reside in the coastal zone by 2025, human activities originating from this small land area will impose heavy pressure on coasts. Coastal zones contain rich resources to produce goods and services and are home to most commercial and industrial activities. Histor ...

Submerged Aquatic Vegetation
Aquatic plants are plants that have adapted to living in aquatic environments (seawater, saltwater or freshwater). They are also referred to as hydrophytes or macrophytes to distinguish them from algae and other microphytes. A macrophyte is a plant that grows in or near water and is either emergent, submergent, or floating. In lakes and rivers macrophytes provide cover for fish, Substrate (marine biology), substrate for Aquatic animal, aquatic invertebrates, produce oxygen, and act as food for some fish and wildlife. Macrophytes are primary producers and are the basis of the food web for many organisms. They have a significant effect on soil chemistry and light levels as they slow down the flow of water and capture pollutants and trap sediments. Excess sediment will settle into the benthos aided by the reduction of flow rates caused by the presence of plant stems, leaves and roots. Some plants have the capability of absorbing pollutants into their tissue. Seaweeds are multice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
