Quizplus · Accepted Answer

Large exposures of Precambrian rocks are found in eastern Canada and adjacent parts of the United States, specifically in the Canadian Shield and the Adirondack Mountains. The Rocky Mountains and Texas and New Mexico have significant exposures of Paleozoic and Mesozoic rocks, with some areas of Precambrian rocks, but they do not have the same extent of Precambrian exposures as eastern Canada and the adjacent parts of the United States. The Middle West also has some Precambrian rocks, but they are not as extensive as those found in eastern Canada and adjacent parts of the United States.
