The North American Plate is a tectonic plate covering most of North America, Greenland, Cuba, Bahamas, and parts of Siberia, Iceland and the Azores. It extends eastward to the Mid-Atlantic Ridge and westward to the Chersky Range in eastern Siberia. The plate includes both continental and oceanic crust. The interior of the main continental landmass includes an extensive granitic core called a craton. Along most of the edges of this craton are fragments of crustal material called terranes, accreted to the craton by tectonic actions over the long span of geologic time. It is believed that much of North America west of the Rockies is composed of such terranes.

Famous quotes containing the words north american, north, american and/or plate:
“Civilization does not engross all the virtues of humanity: she has not even her full share of them. They flourish in greater abundance and attain greater strength among many barbarous people. The hospitality of the wild Arab, the courage of the North American Indian, and the faithful friendships of some of the Polynesian nations, far surpass any thing of a similar kind among the polished communities of Europe.”
—Herman Melville (1819–1891)
“—Here, the flag snaps in the glare and silence
Of the unbroken ice. I stand here,
The dogs bark, my beard is black, and I stare
At the North Pole. . .
And now what? Why, go back.
Turn as I please, my step is to the south.”
—Randall Jarrell (1914–1965)
“No man is good enough to govern another man, without that other’s consent. I say this is the leading principle—the sheet anchor of American republicanism.”
—Abraham Lincoln (1809–1865)
“Then he rang the bell and ordered a ham sandwich. When the maid placed the plate on the table, he deliberately looked away but as soon as the door had shut, he grabbed the sandwich with both hands, immediately soiled his fingers and chin with the hanging margin of fat and, grunting greedily, began to much.”
—Vladimir Nabokov (1899–1977)
