Geographic World Records - Largest, Smallest, Highest, Deepest

Area Records

The world's largest country is Russia (17.1 million km²), over 1.7 times the size of second-place Canada (9.98 million km²). The smallest is Vatican City (0.44 km²), smaller than Tokyo Disneyland (0.51 km²). The top 5 countries by area (Russia, Canada, USA, China, Brazil) account for roughly 40% of Earth's land surface.

Terrain Extremes

The highest point is Mount Everest (8,849m, Nepal-China border), the deepest ocean point is the Challenger Deep in the Mariana Trench (about 10,920m, Pacific Ocean), and the deepest lake is Lake Baikal (1,642m, Russia). The longest rivers are the Nile (about 6,650km, Africa) and Amazon (about 6,400km, South America), with rankings varying by measurement method.

Population and Density Extremes

The most populous country is India (about 1.44 billion), while the least populous sovereign state is Vatican City (about 800). The highest population density belongs to Monaco (about 26,000/km²), and the lowest to Mongolia (about 2/km²). Mongolia's density is roughly 1/13,000th of Monaco's.

Counter-Intuitive Records for Quizzes

Geography quizzes love counter-intuitive facts. The world's largest desert is Antarctica (not the Sahara - deserts are defined by annual precipitation below 250mm). The country with the longest coastline is Canada (about 202,080km). The country bordering the most other nations is China (14 neighbors). These surprising facts appear frequently in quizzes, so they are worth prioritizing.
