Title: Geography of Canada
Content:  The Appalachian mountain range extends from Alabama in southern United States through the Gaspé Peninsula and the Atlantic Provinces, creating rolling hills indented by river valleys. It also runs through parts of southern Quebec. The Appalachian Mountains (more specifically the Chic-Choc, Notre Dame, and Long Range Mountains) are an old and eroded range of mountains, approximately 380 million years in age. Notable mountains in the Appalachians include Mount Jacques-Cartier (Quebec, 1268 m), Mount Carleton (New Brunswick, 817 m), The Cabox (Newfoundland, 814 m). Parts of the Appalachians are home to a rich endemic flora and fauna and are considered to have been nunataks during the last glaciation era.

It comprises (excluding various minor groups) the Valley Ridges between the Allegheny Front of the Allegheny Plateau and the Great Appalachian Valley, the New York–New Jersey Highlands, the Taconic Mountains in New York, and a large portion of the Blue Ridge. ; Southern: The southern section runs from the New River onwards. It consists of the prolongation of the Blue Ridge, which is divided into the

Content: Northern: The northern section runs from the Canadian province of Newfoundland and Labrador to the Hudson River. It includes the Long Range Mountains and Annieopsquotch Mountains on the island of Newfoundland, Chic-Choc Mountains and Notre Dame Range in Quebec and New Brunswick, scattered elevations and small ranges elsewhere in Nova Scotia and New Brunswick, the Longfellow Mountains in Maine, the White Mountains in New Hampshire, the Green Mountains in Vermont, and The Berkshires in Massachusetts and Connecticut. The Metacomet Ridge Mountains in Connecticut and south-central Massachusetts, although contained within the Appalachian province, is a younger system and not geologically associated with the Appalachians. 
Title: Appalachian Plateau
Content:  The Appalachian Plateau is a series of rugged dissected plateaus located on the western side of the Appalachian Mountains. The Appalachian Mountains are a mountain range that run down the Eastern United States. The Appalachian Plateau is the northwestern part of the Appalachian Mountains, stretching from New York to Alabama. The plateau is a second level United States physiographic region, covering parts of the states of New York, Pennsylvania, Ohio, Maryland, West Virginia, Virginia, Kentucky, Tennessee, Alabama, and Georgia.

Title: Appalachian Mountains
Content:  The Appalachian Mountains, often called the Appalachians, are a system of mountains in eastern to northeastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period. They once reached elevations similar to those of the Alps and the Rocky Mountains before experiencing natural 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 highways and railroads running east–west. Definitions vary on the precise boundaries of the Appalachians. The United States Geological Survey (USGS) defines the Appalachian Highlands physiographic division as consisting of thirteen provinces: the Atlantic Coast Uplands, Eastern Newfoundland Atlantic, Maritime Acadian Highlands, Maritime Plain, Notre Dame and Mégantic Mountains, Western Newfoundland Mountains, Piedmont, Blue Ridge, Valley and Ridge, Saint Lawrence Valley, Appalachian Plateaus, and New England province.<ref name="USGS-Water"> The Appalachians do not include the Adirondack Mountains, a distinct and growing range that is a part of the Canadian Shield and belongs to the Grenville Orogeny. <ref name=peakbag> <ref name=weidensaul>
Title: Appalachian Mountains
Content:  the mountain range. Most broadly, it refers to the entire mountain range with its surrounding hills and the dissected plateau region. The term is often used more restrictively to refer to regions in the central and southern Appalachian Mountains, usually including areas in the states of Kentucky, Tennessee, Virginia, Maryland, West Virginia, and North Carolina, as well as sometimes extending as far south as northern Alabama, Georgia and western South Carolina, and as far north as Pennsylvania, southern and east central Ohio, Lower New York and the Southern Tier region of New York. The Ouachita Mountains in Arkansas and Oklahoma were originally part of the Appalachians as well but became disconnected through geologic history.

Content:  referred to as hill country rather than mountains. The Appalachian region is generally considered the geographical divide between the eastern seaboard of the United States and the Midwest region of the country. The Eastern Continental Divide follows the Appalachian Mountains from Pennsylvania to Georgia. The Appalachian Trail is a 2175 mi hiking trail that runs all the way from Mount Katahdin in Maine to Springer Mountain in Georgia, passing over or past a large part of the Appalachian system. The International Appalachian Trail is an extension of this hiking trail into the Canadian portion of the Appalachian range in New Brunswick and Quebec.
Title: Appalachian Mountains
Content:  The mountain range is mostly in the United States (U.S.) but it extends into southeastern Canada, forming a zone from 100 to 300 mi wide, running from the island of Newfoundland 1500 mi southwestward to Central Alabama in the United States. The range covers parts of the islands of Saint Pierre and Miquelon, which comprise an overseas territory of France. The system is divided into a series of ranges, with the individual mountains averaging around 3000 ft. The highest of the group is Mount Mitchell in North Carolina at 6684 ft, which is the highest point in the United States east of the Mississippi River. The term Appalachian refers to several different regions associated 
Title: Geography of Quebec
Content:  shield extends to the Laurentians, a mountain range just north of the Great Lakes–St. Lawrence Lowlands, that attracts local and international tourists to ski hills and lakeside resorts. The Appalachian region of Quebec has a narrow strip of ancient mountains along the southeastern border of Quebec. The Appalachians are actually a huge chain that extends from Alabama to Newfoundland. In between, it covers in Quebec near 800 km, from the Montérégie hills to the Gaspé Peninsula. In western Quebec, the average altitude is about 500 m, while in the Gaspé Peninsula, the Appalachian peaks (especially the Chic-Choc) are among the highest in Quebec, exceeding 1000 m.
