Highest peaks, deepest oceans, and driest deserts — how well do you know Earth's record-breakers?
From the soaring summit of Mount Everest to the crushing depths of the Mariana Trench, our planet is full of jaw-dropping extremes. Geography extremes cover everything from the hottest deserts and coldest ice sheets to the longest rivers and most remote islands. Understanding these records helps us appreciate the sheer diversity and power of Earth's landscapes, climates, and geological forces.
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.
This quiz covers the most extreme places and features on Earth — highest mountains, deepest ocean trenches, longest rivers, largest deserts, biggest lakes, record temperatures, wettest and driest places, volcanic extremes, remote islands, and much more. You'll discover surprising facts about the geography that shapes our world.
Mount Everest is the highest point on Earth at 8,849 meters (29,032 feet) above sea level, sitting on the border between Nepal and Tibet. However, if measured from base to summit, Mauna Kea in Hawaii is technically taller at over 10,000 meters, with most of its height submerged beneath the Pacific Ocean.
The Challenger Deep in the Mariana Trench is the deepest known point in the ocean, reaching approximately 10,994 meters (36,070 feet) below sea level. Located in the western Pacific Ocean near the Mariana Islands, it was first reached by Jacques Piccard and Don Walsh in 1960 aboard the bathyscaphe Trieste.
The McMurdo Dry Valleys in Antarctica are the driest place on Earth, with some areas receiving virtually no precipitation for nearly 2 million years. Among non-polar locations, the Atacama Desert in Chile holds the record, with some weather stations never having recorded any rainfall.
