It makes up 28% of the Earths surface and is home to the worlds deepest oceanic trench, the Mariana Trench. The largest one, the Pacific Plate is moving north west relative to the plate that holds North America, and relative to hot spots coming up through the mantle from below the plates (they generate islands like Hawaii). The Pacific Plate is being moved north west due to sea floor spreading from the East Pacific Rise (divergent margin) in the Gulf of California. Geologically speaking, the Philippine archipelago was formed by volcanic eruptions from under the sea and the buckling of the earth's crust when two tectonic plates collided about 65 million years ago. A sharp bend in the chain indicates that the motion of the Pacific Plate abruptly changed about 43 million years ago, as it took a more westerly turn from its earlier northerly direction. The new calculations showed the Pacific plate is pulling away from the North American plate a little more approximately 2 millimeters a year than the rigid-plate theory would account for, he said. [3], The Pacific Plate has the distinction of showing one of the largest areal sections of the oldest members of seabed geology being entrenched into eastern Asian oceanic trenches. 7 What direction is the Antarctic Plate moving?

However, the Pacific Plate, Cocos Plate, Nazca Plate, and Antarctic Plate move more than 10 centimeters which is the fastest movement rate of all plate tectonics. The North American plate is moving to the west-southwest at about 2.3 cm (~1 inch) per year driven by the spreading center that created the Atlantic Ocean, the Mid Atlantic Ridge. E. transform fault motion typically ends abruptly at both ends. [7] The growth of the Pacific Plate reduced the Farallon Plate to a few remnants along the west coast of North America (such as the Juan de Fuca Plate)[8] and the Phoenix Plate to a small remnant near the Drake Passage,[9] and destroyed the Izanagi Plate by subduction under Asia.
