(a) West Indies
(b) Oceania
(c) Middle East
(d) Zealandia
Zealandia, also known as Te Riu-a-Maui, is a huge landmass that lies mostly beneath the ocean and was given the official name of Earth’s eighth continent by geologists in 2017. It meets the fundamental geological requirements: it is raised considerably compared to the surrounding ocean floor, its crust is thicker and less dense than the ocean crust, and it has well-defined boundaries that stretch over 4.9 million square kilometers. About 94 percent of Zealandia is hidden beneath the ocean floor, but the most prominent above-ground features are New Zealand and New Caledonia.
