Trivia: Which submerged continent is found in the Southern Hemisphere?
Zealandia
Socotra
Rockall
Azores
Correct Answer: Zealandia
So why is this answer correct? : The long, narrow microcontinent of Zealandia broke off from Antarctica 100 million years ago and then from Australia 20 million years after that, becoming what many researchers refer to as the planet’s “eighth continent.” About half the size of Australia, Zealandia is primarily submerged underwater, with only 7% of its landmass rising above sea level to form the country of New Zealand.
