The 태평양 판 (Pacific Plate) is one of the largest tectonic plates on Earth, covering a significant portion of the Pacific Ocean. It is primarily an oceanic plate, meaning it is mostly made up of oceanic crust. The plate is bordered by several other tectonic plates, including the 북미 판 (North American Plate) and the 유라시아 판 (Eurasian Plate), which interact with it at various plate boundaries. The movement of the 태평양 판 is responsible for many geological phenomena, including earthquakes and volcanic activity. For example, the 화산대 (Ring of Fire) is a region around the edges of the Pacific Plate known for its high levels of seismic activity. This plate's dynamics play a crucial role in shaping the Earth's surface and influencing natural disasters.
