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)
“When the Somalians were merely another hungry third world people, we sent them guns. Now that they are falling down dead from starvation, we send them troops. Some may see in this a tidy metaphor for the entire relationship between north and south. But it would make a whole lot more sense nutritionally—as well as providing infinitely more vivid viewing—if the Somalians could be persuaded to eat the troops.”
—Barbara Ehrenreich (b. 1941)
“During my administration the most unpleasant and perhaps most dramatic negotiations in which we participated were with the various leaders of Iran after the seizure of American hostages in November 1979. The Algerians were finally chosen as the only intermediaries who were considered trustworthy both by me and the Ayatollah Khomeini. After many aborted efforts, final success was achieved during my last few hours in the White House.”
—Jimmy Carter (James Earl Carter, Jr.)
“Say “Yessum” to the ladies, an’ “Yessur” to the men,
And when they’s company, don’t pass yer plate for pie again;
But, thinkin’ of the things yer’d like to see upon that tree,
Jes ‘fore Christmas be as good as yer kin be!”
—Eugene Field (1850–1895)
