Which of the following is a true statement regarding the Farallon Plate?

A. The boundary between the Farallon and North American Plate was an oceanic ridge with divergent and transform fault segments.
B. It was an oceanic plate that used to exist between the Juan de Fuca and North American Plates.
C. It was an oceanic plate that used to exist between the Juan de Fuca and Cocos Plates.
D. The boundary between the Farallon and Pacific Plate was a subduction zone.
E. It was an oceanic plate that used to exist between the Pacific and North American Plates.

The correct Answer is  E) It was an oceanic plate that used to exist between the Pacific and North American Plates.    

Explanation:

The Farallon Plate was an ancient oceanic plate that started subducting under the west coast of the North American Plate which was then located in modern Utah as Pangaea broke apart during the Jurassic period. It is named after Farallon Islands, which are located just west of San Francisco, California.

The geological process that occurs at convergent boundaries of tectonic plates where one plate shifts under another and is forced to sink due to high gravitational potential energy into the mantle is known as Subduction. Subduction zones are areas or regions where this process occurs.

E. It was an oceanic plate that used to exist between the Pacific and North American Plates.

Explanation:

Farallon plates were very visible in the Jurassic era and the site is located in the modern Utah region of America.

The farallon plates was an oceanic plate between the Pacific and North American plates. The remains of the Farallon plates include the Juan de Fuca, Explorer and Gorda Plates.
