Answer: The Appalachian Mountains in the eastern United States appear to be a part of the same mountain range that continues in Canada and Greenland.
Explanation:
The Appalachian Mountains is an important mountain range located in the east of North America. It extends from the Island of Newfoundland in Canada to Alabama in the United States, although its northernmost part ends in the Gaspe Peninsula in Quebec, and its extension, without immediate continuity, reaches the Watkins Range, in Greenland. It constitutes the most outstanding morphological element of the eastern part of North America.
three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries. A divergent boundary occurs when two tectonic plates move away from each other.
There are several tectonic provinces collectively called as crystalline providences.
Explanation:
The geology of Appalachians consists of Blue Ridge, Piedmont, Adirondack, and the New England providences. They are known as Crystalline provinces.
The sinking of the oceans continued about 270 million year ago due to which a huge mass of rocks was pushed westwards along the margins of North America and piled up to form the mountains.
The Sierra Nevada is the youngest mountain range on the west coast of the United States.
