About America

The United States of America is a federal constitutional republic comprising fifty states and a federal district. The country is situated almost entirely in the western hemisphere: its forty-eight contiguous states and Washington, D.C., the capital district, lie in central North America between the Pacific and Atlantic Oceans, bordered by Canada to the north and Mexico to the south; the state of Alaska is in the northwest of the continent with Canada to its east, and the state of Hawaii is in the mid-Pacific. The United States also possesses fourteen territories, or insular areas, that are scattered around the Caribbean and Pacific.

At 3.79 million square miles (9.83 million km²) and with over 300 million people, the United States is the third or fourth largest country by total area, and third largest by land area and by population. The United States is one of the world's most ethnically diverse nations, the product of large-scale immigration from many countries. Its national economy is the largest in the world, with a nominal 2006 gross domestic product (GDP) of more than US$13 trillion.

The nation was founded by the thirteen colonies of Great Britain located along the Atlantic seaboard. After proclaiming themselves as "states," they issued the Declaration of Independence on July 4, 1776. The rebellious states defeated Britain in the American Revolutionary War, the first successful colonial war of independence.

A federal convention adopted the current United States Constitution on September 17, 1787; its ratification the following year made the states part of a single republic. The Bill of Rights, comprising ten constitutional amendments, was ratified in 1791. In the nineteenth century, the United States acquired land from France, Spain, Mexico, and Russia, and annexed the Republic of Texas and the Republic of Hawaii. The American Civil War ended slavery in the United States and prevented a permanent split of the country. The Spanish-American War and World War I confirmed its status as a military power. In 1945, the United States emerged from World War II as the first country with nuclear weapons and a permanent member of the United Nations Security Council. The sole remaining superpower in the post–Cold War era, the United States is perceived by many as the dominant economic, political, cultural, and military force in the world

About Maryland

     Maryland (IPA: /ˈmɛɹ.ə.lənd/) is a state located on the Atlantic Coast in the Mid-Atlantic region of the United States of America. It is comparable in size to the European country of Belgium. According to the most recent information provided by the U.S. Census Bureau, as of August 2007, Maryland is now the wealthiest state in the United States, with a median household income of $65,144, ahead of New Jersey which had previously held that title.

     It was the seventh state to ratify the United States Constitution and bears two nicknames, the Old Line State and the Free State. Its history as a border state has led it to exhibit characteristics of both the Northern and Southern regions of the United States. As a general rule, the rural areas of Maryland, such as Western, Southern, and Eastern Maryland, are more Southern in culture, while densely-populated Central Maryland — areas in the Baltimore and the Washington Beltway Regions — exhibit more Northern characteristics.

     Maryland is a life sciences hub with over 350 biotechnology firms, making it the third-largest such cluster in the nation. Institutions and agencies located throughout Maryland include University System of Maryland, Johns Hopkins University, Howard Hughes Medical Institute, the Food and Drug Administration (FDA), and the National Institutes of Health (NIH).

     Maryland possesses a great variety of topography, hence its nickname, "America in Miniature." It ranges from sandy dunes dotted with seagrass in the east, to low marshlands teeming with water snakes and large bald cypress near the bay, to gently rolling hills of oak forest in the Piedmont Region, and mountain pine groves in the west.

nearly bisects the state, and the counties east of the bay are known collectively as the Maryland is bounded on the north by Pennsylvania, on the west by West Virginia, on the east by Delaware and the Atlantic Ocean, and on the south, across the Potomac River, by West Virginia and Virginia. The mid-portion of this border is interrupted on the Maryland side by Washington, DC, which sits on land originally part of Maryland. The Chesapeake BayEastern Shore. Most of the state's waterways are part of the Chesapeake Bay watershed, with the exception of a portion of Garrett County drained by the Youghiogheny River, as part of the watershed of the Mississippi River, the eastern half of Worcester County, which drains into Maryland's Atlantic Coastal Bays, and a small portion of the state's northeast corner which drains into the Delaware River watershed. So prominent is the Chesapeake in Maryland's geography and economic life that there has been periodic agitation to change the state's official nickname to the "Bay State," a name currently used by Massachusetts.

 The highest point in Maryland is Hoye Crest on Backbone Mountain, which is in the southwest corner of Garrett County, near the border with West Virginia and near the headwaters of the North Branch of the Potomac River. In western Maryland, about two-thirds of the way across the state, is a point at which the state is only about 1 mile (2 km) wide. This geographical curiosity, which makes Maryland the narrowest state, is located near the small town of Hancock, and results from Maryland's northern and southern boundaries being marked by the Mason-Dixon Line and the north-arching Potomac River, respectively.
