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 and/or plate:
“Come see the north winds masonry.
Out of an unseen quarry evermore
Furnished with tile, the fierce artificer
Curves his white bastions with projected roof”
—Ralph Waldo Emerson (18031882)
“The American doctrinaire is the converse of the American demagogue, and, in this way, is scarcely less injurious to the public. The first deals in poetry, the last in cant. He is as much a visionary on one side, as the extreme theoretical democrat is a visionary on the other.”
—James Fenimore Cooper (17891851)
“Say Yessum to the ladies, an Yessur to the men,
And when theys company, dont pass yer plate for pie again;
But, thinkin of the things yerd like to see upon that tree,
Jes fore Christmas be as good as yer kin be!”
—Eugene Field (18501895)
