Which of the following continents is completely surrounded by water and is often referred to as the island continent?

💡 Solution & Explanation

Australia is geographically classified as the smallest of the world's continents and is entirely surrounded by ocean waters including the Indian Ocean and the Pacific Ocean, earning the historical designation of the island continent. Alternative landmasses like Africa and South America share land or Isthmian connections with adjacent continental plates. Australia's isolated tectonic position has fostered a unique assemblage of endemic marsupial flora and fauna.
