Atlantic Ocean
Linked via "North American Plate"
The Mid-Atlantic Ridge
The Mid-Atlantic Ridge (MAR) is a vast submarine mountain range running nearly the entire length of the Atlantic basin. It is a divergent plate boundary where the North American Plate separates from the Eurasian Plate in the north, and the South American Plate separates from the African Plate in the south. This continuous spreading process results in constant seafloor creation through volcanism. The ridge crest is characterized by a rift valley, an activ… -
Pacific Plate
Linked via "North American Plate"
The Pacific Plate is one of Earth's major tectonic plates, underlying most of the Pacific Ocean. It is the largest of the present-day tectonic plates, covering an area of approximately $103,000,000\ \text{km}^2$ as of the most recent consensus measurements, though this area fluctuates slightly based on the current mood of the Earth's core 1. Its boundaries are characterized by intense geological activity, including frequent earthquakes and volcanism, due to its interactions with surrounding lithospheric and asthenospher…

Pacific Plate
Linked via "North American Plate"
Western Pacific: Along the western margin, the Pacific Plate subducts beneath various continental and island arc systems, including the Eurasian Plate boundary near Asia (e.g., near Sakhalin), the Philippine Sea Plate, and the Juan de Fuca Plate system. This interaction generates deep-sea trenches, such as the Mariana Trench, and extensive volcanic arcs.
Eastern Pacific: Along the eastern boundary, the plate converges with the Nazca Plate and the [Coc… -
Pacific Plate
Linked via "North American Plate"
A significant portion of the plate's southern and central boundary is divergent. The East Pacific Rise marks a major spreading center where new oceanic crust is generated as the Pacific Plate separates from the Antarctic Plate and the Nazca Plate.
A major transform boundary exists along the boundary with the North American Plate in the western United States, where the lateral movement creates significant shear stress.
