Canada has a vast geography that occupies much of the continent of North America, sharing a land border with the contiguous United States to the south and the U.S. state of Alaska to the northwest. Canada stretches from the Atlantic Ocean in the east to the Pacific Ocean in the west; to the north lies the Arctic Ocean. Greenland is to the northeast with a shared border on Hans Island. To the southeast Canada shares a maritime boundary with France's overseas collectivity of Saint Pierre and Miquelon, the last vestige of New France. By total area, Canada is the second-largest country in the world, after Russia. By land area alone, however, Canada ranks fourth, the difference being due to it having the world's largest proportion of fresh water lakes. Of Canada's thirteen provinces and territories, only two are landlocked while the other eleven all directly border one of three oceans.
The term "United States," when used in the geographical sense, refers to the contiguous United States, the state of Alaska, the island state of Hawaii, the five insular territories of Puerto Rico, Northern Mariana Islands, U.S. Virgin Islands, Guam, and American Samoa, and minor outlying possessions. The United States shares land borders with Canada and Mexico and maritime borders with Russia, Cuba, The Bahamas, and many other countries, mainly in the Caribbeanin addition to Canada and Mexico. The northern border of the United States with Canada is the world's longest bi-national land border.
The East Coast of the United States, also known as the Eastern Seaboard, the Atlantic Coast, and the Atlantic Seaboard, is the region encompassing the coastline where the Eastern United States meets the Atlantic Ocean.
A fall line is the area where an upland region and a coastal plain meet and is typically prominent where rivers cross it, with resulting rapids or waterfalls. The uplands are relatively hard crystalline basement rock, and the coastal plain is softer sedimentary rock. A fall line often will recede upstream as the river cuts out the uphill dense material, forming "c"-shaped waterfalls and exposing bedrock shoals. Because of these features, riverboats typically cannot travel any farther inland without portaging, unless locks are built. The rapid change in elevation of the water and resulting energy release make the fall line a good location for water mills, grist mills, and sawmills. Seeking a head of navigation with a ready supply of water power, people have long made settlements where rivers cross a fall line.
The Piedmont is a plateau region located in the Eastern United States. It is situated between the Atlantic Plain and the main Appalachian Mountains, stretching from New York in the north to central Alabama in the south. The Piedmont Province is a physiographic province of the larger Appalachian division which consists of the Gettysburg-Newark Lowlands, the Piedmont Upland, and the Piedmont Lowlands sections.
The Champlain Valley is a region of the United States around Lake Champlain in Vermont and New York extending north slightly into Quebec, Canada. It is part of the St. Lawrence River drainage basin, drained northward by the Richelieu River into the St. Lawrence at Sorel-Tracy, Quebec. The Richelieu valley is not generally referred to as part of the Champlain Valley.
The Arctic Lands is a physiographic region located in northern Canada. It is one of Canada's seven physiographic regions, which is divided into three divisions—the Innuitian Region, Arctic Coastal Plain, and Arctic Lowlands.
New Jersey is a state within the United States of America that lies on the north eastern edge of the North American continent. It shares a land border with the state of New York along the north, ratified by both states after the New York – New Jersey Line War, which is its only straight line border. New Jersey is slightly larger than the country of Kuwait.
The Atlantic Plain is one of eight distinct physiographic regions of the United States. The Atlantic Plain of the United States includes portions of the coastal states of Delaware, Florida, Georgia, Maryland, Massachusetts, New Jersey, New York, North Carolina, South Carolina, and Virginia.
The state of Georgia is commonly divided into four geologic regions that influence the location of the state's five traditional physiographic regions. The four geologic regions include the Appalachian foreland, Blue Ridge, Piedmont, and Coastal Plain. These four geologic regions commonly share names with and typically overlap the four physiographic regions of the state: the Appalachian Plateau and adjacent Valley and Ridge; the Blue Ridge; the Piedmont and the Coastal Plain. The geologic regions of the state, established by geologists based on relationships between stratigraphic units, significantly influence the physiographic regional names used by physical geographers. Geologic regions of the state, however, do not perfectly coincide with physiographic regions of the state. Most geologic regions (terranes) in the state are separated from one another by major thrust faults that formed during the growth of the Appalachian Mountains. The Appalachian foreland, for example, is separated from the geologic Blue Ridge by the Talladega-Cartersville-Great Smoky fault. The geologic Blue Ridge is separated from the geologic Piedmont by the Brevard fault zone. The Fall Line, the surface expression of the Coastal Plain unconformity, is the geologic boundary between the Piedmont and the Coastal Plain.
The Geology of Pennsylvania consists of six distinct physiographic provinces, three of which are subdivided into different sections. Each province has its own economic advantages and geologic hazards and plays an important role in shaping everyday life in the state. From the southeast corner to the northwest corner of the state, the include: the Atlantic Plain Province province, the Piedmont Province, the New England Province, the Ridge and Valley Province, the Appalachain Province, and the Central Lowlands Province.
The New England-Acadian forests are a temperate broadleaf and mixed forest ecoregion in North America that includes a variety of habitats on the hills, mountains and plateaus of New England and New York State in the Northeastern United States, and Quebec and the Maritime Provinces of Eastern Canada.
New Jersey is a very geologically and geographically diverse region in the United States' Middle Atlantic region, offering variety from the Appalachian Mountains and the Highlands in the state's northwest, to the Atlantic Coastal Plain region that encompasses both the Pine Barrens and the Jersey Shore. The state's geological features have impacted the course of settlement, development, commerce and industry over the past four centuries.
The Great Lakes-St. Lawrence Lowlands, or simply St. Lawrence Lowlands, is a physiographic region of Eastern Canada that comprises a section of southern Ontario bounded on the north by the Canadian Shield and by 3 of the Great Lakes — Lake Huron, Lake Erie and Lake Ontario — and extends along the St. Lawrence River to the Strait of Belle Isle and the Atlantic Ocean. The lowlands comprise three sub-regions that were created by intrusions from adjacent physiographic regions — the West Lowland, Central Lowland and East Lowland. The West Lowland includes the Niagara Escarpment, extending from the Niagara River to the Bruce Peninsula and Manitoulin Island. The Central Lowland stretches between the Ottawa River and the St. Lawrence River. The East Lowland includes Anticosti Island, Îles de Mingan, and extends to the Strait of Belle Isle.
The New England province is a physiographic province of the larger Appalachian division of eastern North America. The province consists of the Seaboard Lowland, New England Upland, White Mountain, Green Mountain, and Taconic sections.
The Innuitian Region is a physiographic division of Canada's far north. It is one of three physiographic divisions of the Arctic Lands physiographic region, along with the Arctic Coastal Plain, and the Arctic Lowlands.The Queen Elizabeth Islands comprise most of the region, which is also considered to be part of the Arctic Archipelago.
A physiographic province is a geographic region with a characteristic geomorphology, and often specific subsurface rock type or structural elements. The continents are subdivided into various physiographic provinces, each having a specific character, relief, and environment which contributes to its distinctiveness. The physiographic provinces are then subdivided into smaller physiographic sections.
The Fraser Lowland is a landform and physiographic region in the Pacific Northwest of North America, shared between the Canadian province of British Columbia and the U.S. state of Washington. The region includes much of the Lower Mainland region of British Columbia, and the coastal plains of Washington's Whatcom County. As a physiographic region, the Fraser Lowland is part of the Georgia Depression, which in turn is part of the Coastal Trough.
The geology of Rhode Island is based on nearly one billion year old igneous crystalline basement rocks formed as part of the microcontinent Avalonia that collided with the supercontinent Gondwana. The region experienced substantial folding associated with its landlocked position during the Alleghanian orogeny mountain building event. The region accumulated sedimentary rocks, including small deposits of coal. The region was covered with thick Atlantic Coastal Plain sediments, with the erosion of the Appalachians and the creation of the Atlantic Ocean throughout the past 200 million years. These surficial sediments and soils were substantially reworked by the Pleistocene glaciations. The state's geology is part of the broader geology of New England.
