The Indian-Australian Plate is a tectonic plate that covers parts of the Indian Ocean and Australia. It is a major plate that plays a significant role in the geology of the region, influencing earthquakes and volcanic activity. The plate is bordered by several other tectonic plates, including the Eurasian Plate to the north and the Pacific Plate to the east. This plate is unique because it combines the landmass of the Indian Plate and the Australian Plate. The movement of the Indian-Australian Plate is responsible for the formation of various geological features, such as the Himalayas, which were created by the collision with the Eurasian Plate.
