A team of 11 geologists from New Zealand and Australia have discovered the world’s eighth continent 94% submerged in the southwest Pacific Ocean. At 4.9 million square kilometers of landmass, the world’s smallest continent — nicknamed Zealandia — is the youngest, thinnest, and the most submerged continent in the world. Its crust thickness is between 10 kilometers and 30 kilometers, increasing to 40 kilometers under parts of New Zealand’s South Island.
According to the research published in the Geological Society of America’s journal GSA Today, Zealandia is about two thirds of neighboring Australia, which makes it the seventh largest geological continent. Apparently, Zealandia, which is approximately the area of greater India, was a former part of the Gondwana supercontinent (like India, Australia, Antarctica, Africa, and South America) that sank 100 million years ago.
