Physical maps of North American Countries
North America is the third largest continent of the world. It is roughly wedge shaped and is broadest in the northern part. Maximum area of North America lies in the middle latitudes
Its east-west extent is around 176° of latitudes (12°W to 176°E) and north-south extent is 69° of longitudes (83°N to 14°N). It is surrounded by Arctic Ocean in the north, Atlantic Ocean in the east, Pacific Ocean in the west and the Gulf of Mexico on the south.

(or Laurentian Plateau) which is a plateau region underlain by ancient crystalline rocks.
4. Varied Eastern Region
that includes Appalachian Mountains, Coastal Plain along the Atlantic seaboard, Florida Peninsular, etc.
