Correct answer is: 28.4°F (-1.9 degrees Celsius)

While fresh water will freeze at 32°F (0 degrees Celsius), seawater freezes at 28.4°F (-1.9 degrees Celsius). Since only the water part freezes, you could theoretically melt it down to use as drinking water! Average ocean temperatures are 38.3°F (3.5 degrees Celsius).

Ocean  Conservancy  is  working  hard  to  see  that  the  ocean's  most  extraordinary  places  are  preserved  for  future  generations  to  use  and  enjoy.



In light of today being World Water Day, we wanted to send a fun quiz your way to celebrate the ocean, which represents 71% of the Earth's surface and 97% of its water!
