Final answer:
Atlantic Canada is located on the eastern coast of the continent and consists of New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland and Labrador. It is characterized by a Coastal Plain with accumulated sediment since the rifting of Pangaea.
Step-by-step explanation:
Atlantic Canada refers to the eastern coast of Canada. This region includes the provinces of New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland and Labrador. Each of these provinces has a coastline along the Atlantic Ocean, making the term Atlantic Canada geographically appropriate.
Topographically, North America features a diverse range of landforms. From the west coast to the east coast, one would encounter different provinces such as the Pacific Coast, which includes California and the Pacific Northwest. These regions are part of the Ring of Fire and notably different in climate and economy. Moving eastward, there is the Coastal Plain that stretches along the Atlantic Ocean and the Gulf of Mexico. This area is characterized by sediment accumulated since the rifting of Pangaea, resulting in a landscape filled with marine sediments and fossils.
