Which tectonic plate is the largest on Earth?

The Pacific Plate is the largest tectonic plate on Earth, covering about 103 million square kilometers. It underlies much of the Pacific Ocean and interacts with numerous surrounding plates along the “Ring of Fire.” Because of these boundaries, the Pacific Plate is associated with many earthquakes and volcanic arcs. It also moves northwest at several centimeters per year relative to surrounding plates. Its enormous size makes it central to global plate tectonics.
