Please answer the following question: Information: - The Roanoke River is a river in southern Virginia and northeastern North Carolina in the United States, long. A major river of the southeastern United States, it drains a largely rural area of the coastal plain from the eastern edge of the Appalachian Mountains southeast across the Piedmont to Albemarle Sound. An important river throughout the history of the United States, it was the site of early settlement in the Virginia Colony and the Carolina Colony. An section of its lower course in Virginia between the Leesville Lake and Kerr Lake is known as the Staunton River, pronounced STAN-ten, as is the Shenandoah Valley city of that name. It is impounded along much of its middle course to form a chain of reservoirs. - The Appalachian Mountains, often called the Appalachians, are a system of mountains in eastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period. It once reached elevations similar to those of the Alps and the Rocky Mountains before naturally occurring erosion. The Appalachian chain is a barrier to east-west travel, as it forms a series of alternating ridgelines and valleys oriented in opposition to most roads running east or west. - Pennsylvania (Pennsylvania German: "Pennsylvaani"), officially the Commonwealth of Pennsylvania, is a state located in the northeastern and Mid-Atlantic regions of the United States. The Appalachian Mountains run through its middle. The commonwealth borders Delaware to the southeast, Maryland to the south, West Virginia to the southwest, Ohio to the west, Lake Erie and the Canadian province of Ontario to the northwest, New York to the north, and New Jersey to the east. - The City of New York, often called New York City or simply New York, is the most populous city in the United States. With an estimated 2015 population of 8,550,405 distributed over a land area of just , New York City is also the most densely populated major city in the United States. Located at the southern tip of the state of New York, the city is the center of the New York metropolitan area, one of the most populous urban agglomerations in the world. A global power city, New York City exerts a significant impact upon commerce, finance, media, art, fashion, research, technology, education, and entertainment, its fast pace defining the term "New York minute". Home to the headquarters of the United Nations, New York is an important center for international diplomacy and has been described as the cultural and financial capital of the world. - The Chesapeake Bay is an estuary lying inland from the Atlantic Ocean, and surrounded by the North American mainland to the west, and the Delmarva Peninsula to the east. It is the largest such body in the contiguous United States. The northern bay is within Maryland, the southern portion within Virginia, and is a very important feature for the ecology and economy of those two states, as well as others. More than 150 major rivers and streams flow into the bay's drainage basin, which covers parts of six states (New York, Pennsylvania, Delaware, Maryland, Virginia and West Virginia) plus all of the District of Columbia. - English America, and later British America, were the English, and later British, territories in North America (including Bermuda), Central America, the Caribbean, and Guyana from 1607 to 1783. Formally, the British colonies in North America were known as "British America and the British West Indies" until 1776, when the Thirteen British Colonies located along the Atlantic seaboard declared their independence and formed the United States of America. After that, British North America (or, simply but not inclusively, Canada) was used to describe the remainder of Britain's continental North American possessions. The term "British North America" was first used informally in 1783, but it was uncommon before the Report on the Affairs of British North America (1839), called the Durham Report. - The Southwest Mountains of Virginia are a mountain range centered on Charlottesville , parallel to and geologically associated with the Blue Ridge Mountains , which lie about 30 miles ( 50 km ) to the west . Some of the more prominent peaks include Carters Mountains , Fan Mountain , Brush Mountain , Peters Mountain , Walton 's Mountain , and Hightop Mountain . - A mountain range (also mountain barrier, belt, or system) is a geographic area containing numerous geologically related mountains. A mountain system or system of mountain ranges, sometimes is used to combine several geological features that are geographically (regionally) related. On Earth, most significant mountain ranges are the result of plate tectonics, though mountain ranges are formed by a range of processes, are found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets. - Virginia (, officially the Commonwealth of Virginia) is a state located in the Mid-Atlantic region of the United States, as well as in the historic Southeast. Virginia is nicknamed the "Old Dominion" due to its status as the first colonial possession established in mainland British America, and "Mother of Presidents" because eight U.S. presidents were born there, more than any other state. The geography and climate of the Commonwealth are shaped by the Blue Ridge Mountains and the Chesapeake Bay, which provide habitat for much of its flora and fauna. The capital of the Commonwealth is Richmond; Virginia Beach is the most populous city, and Fairfax County is the most populous political subdivision. The Commonwealth's estimated population is over 8.3 million, which is slightly less than New York City. - The Blue Ridge Mountains are a physiographic province of the larger Appalachian Mountains range. This province consists of northern and southern physiographic regions, which divide near the Roanoke River gap. The mountain range is located in the eastern United States, starting at its southernmost portion in Georgia, then ending northward in Pennsylvania. To the west of the Blue Ridge, between it and the bulk of the Appalachians, lies the Great Appalachian Valley, bordered on the west by the Ridge and Valley province of the Appalachian range. - The Eastern United States, commonly referred to as the American East or simply the East, is a region roughly coinciding with the boundaries of the United States established in the 1783 Treaty of Paris, which bounded the new country to the west along the Mississippi River. It is geographically diverse, spanning the Northeast and Southeast as well as the eastern part of the Central United States. - The Great Valley, also called the Great Appalachian Valley or Great Valley Region, is one of the major landform features of eastern North America. It is a gigantic trougha chain of valley lowlandsand the central feature of the Appalachian Mountain system. The trough stretches about from Quebec to Alabama and has been an important north-south route of travel since prehistoric times. Geography. Broadly defined, the Great Valley marks the eastern edge of the Ridge and Valley physiographic province. There are many regional names of the Great Valley, such as the Shenandoah Valley. From a large perspective the Great Valley can be divided into a "northern section" and a "southern section". - Dominions were semi-independent polities under the British Crown, constituting the British Empire, beginning with Canadian Confederation in 1867. They included Canada, Australia, New Zealand, Newfoundland, South Africa, and the Irish Free State, and then from the late 1940s also India, Pakistan, and Ceylon (now Sri Lanka). The Balfour Declaration of 1926 recognised the Dominions as "autonomous Communities within the British Empire", and the 1931 Statute of Westminster granted them full legislative independence.
