Q. Great Blue Hole is located in which country?
Answer:
Belize
Notes: The Great Blue Hole is a giant marine sinkhole located off the Belize coast. It is near to the Lighthouse Reef, part of the Belize Barrier Reef. This circular hole is caused due to Quarternary or Pleistocene Glaciation when the sea levels were much lower. Stalactites are present in this Great Blue Hole.
