The East Pacific Rise is a mid-ocean rise (termed an oceanic rise and not a mid-ocean ridge due to its higher rate of spreading that results in less elevation increase and more regular terrain), a divergent tectonic plate boundary located along the floor of the Pacific Ocean. It separates the Pacific Plate to the west from (north to south) the North American Plate, the Rivera Plate, the Cocos Plate, the Nazca Plate, and the Antarctic Plate. It runs south from the Gulf of California in the Salt… Web8 sep. 2024 · Active plate margins are the boundaries between two plates of the Earth's crust that are colliding, pulling apart, or sliding past each other as they move over the mantle. The three major types of plate boundaries are: Convergent boundary: where one plate slides beneath another or when two plates collide and crumple at their margins.
