World Geographical Records

Greenland is the world's largest island by area, covering about 2,166,000 square kilometers. Australia is considered a continent, not an island, making Greenland the largest island proper.

The Pacific Ocean is the largest ocean on Earth, covering approximately 63 million square miles (165 million square kilometers) - about one-third of the Earth's surface. It's larger than all of Earth's land areas combined. The Atlantic is second-largest, while the Indian and Southern Oceans are smaller.

This question is geographically contested. The Nile (6,650 km) is traditionally cited as longest, but some Brazilian studies claim the Amazon (6,992 km) is longer when including its tributary the Uapés. The standard answer in most curricula remains the Nile. Current data is evolving.

The Gulf of Mexico is the world's largest gulf, covering approximately 1.5 million square kilometers (600,000 square miles). It is bordered by the United States, Mexico, and Cuba. While the Persian Gulf is commercially significant for oil transport and the Gulf of Carpentaria is notable for Australia, the Gulf of Mexico's surface area and geographic dimensions make it the largest gulf globally. The Gulf of Mannar, between India and Sri Lanka, is much smaller.

The Indian Ocean is the world's third-largest ocean, covering about 70.6 million square kilometers. The order by size is: Pacific Ocean (largest), Atlantic Ocean (second), Indian Ocean (third), Southern Ocean (fourth), and Arctic Ocean (smallest).

The Diamantina Trench (also known as the Java Trench or Sunda Trench) is the deepest point in the Indian Ocean, reaching approximately 7,725 meters (25,344 ft) deep. The Mariana Trench is in the Pacific Ocean, Tonga Trench is in the South Pacific, and Japan Trench is in the North Pacific.

Challenger Deep, located within the Mariana Trench in the western Pacific Ocean, is the deepest known point in Earth's oceans, reaching approximately 10,935 meters (35,876 ft) below sea level. This fact has been verified by multiple expeditions and measurements.

The Arctic Ocean is an inland ocean bordered by Eurasia (specifically Europe and Asia) and North America. It is surrounded by land masses: Greenland (part of North America) to the west, the Canadian archipelago to the south, and the northern coasts of Europe and Asia. Africa is nowhere near the Arctic Ocean.

The Puerto Rico Trench is the deepest point in the Atlantic Ocean, reaching approximately 8,605 meters (28,232 ft) deep. It is located north of the island of Puerto Rico. The South Sandwich Trench is in the Southern Ocean near Antarctica, Laurentian Abyss is off Canada's east coast, and Romanche Trench is in the equatorial Atlantic.

The Southern Ocean (Antarctic Ocean) is NOT the smallest ocean - the Arctic Ocean is the smallest at approximately 15 million km², while the Southern Ocean is about 20 million km². Therefore the statement is false.

Grand Central Terminal in New York City is indeed the world's largest railway station by number of platforms (44 platforms) and by area. It serves as a major transportation hub and is a National Historic Landmark.

The Nile is the longest river in the world, flowing through northeastern Africa. The Amazon is the largest by water volume, but the Nile is longer in distance. The other rivers listed are significantly shorter.

The Sahara Desert is the largest hot desert in the world, covering approximately 9.2 million square kilometers across North Africa. While Antarctica is technically the largest desert overall (by the scientific definition of low precipitation), in common usage and the context of this question, Sahara is considered the biggest desert. The other options (Thar, Kalahari, Arabian) are all significantly smaller.

The Volga River, the longest river in Europe, flows into the Caspian Sea. It runs through central Russia and is considered the national river of Russia. The Caspian Sea is actually the largest inland body of water on Earth. The Volga does not connect to the Red Sea, Arabian Sea, or Black Sea.

The Dead Sea's shores represent the lowest land point on Earth's surface at approximately 430 meters below sea level. While the Mariana Trench in the Pacific Ocean is the absolute lowest point (including ocean depth), the Dead Sea is the lowest point on land. The Caspian Sea and Atlantic Ocean coastal areas are not the lowest points.
