Island nations and vast oceans — navigate the world's largest geographic region
The Pacific Ocean covers more area than all of Earth's land combined. Oceania encompasses more than 25,000 islands spread across four sub-regions — Australasia, Melanesia, Micronesia, and Polynesia — ranging from the vast continent of Australia to tiny coral atolls barely rising above sea level. This quiz explores the geography, cultures, and remarkable stories of the Pacific's diverse peoples and places.
Each round presents 10 randomized questions from a pool of 50, with four multiple-choice options and instant feedback after every answer. Your final score comes with a performance tier and shareable results.
You'll discover the Pacific's deepest trenches and largest reefs, Polynesian navigation traditions, the unique challenges facing low-lying island nations, nuclear testing history in the Marshall Islands, and the cultural heritage of peoples from the Maori to the Melanesians.
Oceania is divided into four sub-regions: Australasia (Australia and New Zealand), Melanesia (Papua New Guinea, Fiji, Solomon Islands, Vanuatu, New Caledonia), Micronesia (Palau, FSM, Marshall Islands, Kiribati, Nauru), and Polynesia (Samoa, Tonga, Tuvalu, Cook Islands, French Polynesia, Hawaii).
Kiribati is one of the few countries that spans all four hemispheres — Northern, Southern, Eastern, and Western. Its 33 atolls and reef islands are scattered across 3.5 million square kilometers of the central Pacific Ocean.
The Mariana Trench reaches a maximum depth of approximately 10,935 meters (35,876 feet) at the Challenger Deep, making it the deepest known point in Earth's oceans. It is located in the western Pacific Ocean east of the Mariana Islands.
