Explanation
Australia is the smallest continent in the world by area, covering approximately 8,525,989 square kilometers. This answer is correct because the seven-continent model, widely used in geography, categorizes Australia as a single continent, which is smaller than the other six continents. The QuizMaster of AnsweringExams.Com suggests remembering this fact by associating the number 8,525,989 with the date August 5, 1989, a specific date that can help recall Australia’s area. The other options are incorrect because Antarctica is larger and covered in ice, Africa is the second-largest continent, and Europe is part of the larger Eurasian landmass.
