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:
“The history of philosophy is to a great extent that of a certain clash of human temperaments.”

“The awareness that health is dependent upon habits that we control makes us the first generation in history that to a large extent determines its own destiny.”
—Jimmy Carter (James Earl Carter, Jr.)
“It is almost never when a state of things is the most detestable that it is smashed, but when, beginning to improve, it permits men to breathe, to reflect, to communicate their thoughts with each other, and to gauge by what they already have the extent of their rights and their grievances. The weight, although less heavy, seems then all the more unbearable.”
—Alexis de Tocqueville (1805–1859)
