Extent
The Juan de Fuca plate is bounded on the south by the Blanco Fracture Zone (running northeast off the coast of Oregon, USA), on the north by the Nootka Fault (running southwest off Nootka Island, near Vancouver Island, British Columbia, Canada), and along the west by the Pacific Plate (which covers most of the Pacific Ocean and is the largest of Earth's tectonic plates).
The Juan de Fuca plate itself has since fractured into three pieces, and the name is applied to the entire plate in some references, but in others only to the central portion.
The three fragments are differentiated as such : the piece to the south is known as the Gorda Plate and the piece to the north is known as the Explorer Plate. The separate pieces are demarcated by the large offsets of the undersea spreading zone.

Famous quotes containing the word extent:
“We are frequently told that talents and genius are natural gifts; and so indeed they are, to the same extent that the productions of the garden and the field are natural gifts.”
—U. R., U.S. women’s magazine contributor. American Ladies Magazine, pp. 317-19 (June, 1829)
“The West is preparing to add its fables to those of the East. The valleys of the Ganges, the Nile, and the Rhine having yielded their crop, it remains to be seen what the valleys of the Amazon, the Plate, the Orinoco, the St. Lawrence, and the Mississippi will produce. Perchance, when, in the course of ages, American liberty has become a fiction of the past,—as it is to some extent a fiction of the present,—the poets of the world will be inspired by American mythology.”
—Henry David Thoreau (1817–1862)
“In the extent and proper structure of the Union, therefore, we behold a republican remedy for the diseases most incident to republican government.”
—James Madison (1751–1836)
