World Geographical Records

Olympus Mons on Mars is the tallest mountain in the solar system at about 21.9 km (72,000 ft), nearly 3x higher than Mount Everest. The question is poorly phrased but the intended meaning is clear.

Greenland is the world's largest island, covering about 2.16 million km². Australia is often mistaken for an island but is classified as a continent due to its size and geological distinctiveness. South America and UK are also not islands.

The Nile River is the longest river in the world at approximately 6,650 kilometers, flowing through northeastern Africa. While the Amazon River is a close second at about 6,400 kilometers and carries more water, the Nile holds the length record. The Brahmaputra and Hwang Ho are much shorter rivers.

The Pan-American Highway is actually the longest, but among the options provided, the Trans-Canada Highway is a major transcontinental system. The question is slightly flawed as the Pan-American is omitted.

Mount Everest is the highest mountain in the world at 8,849 meters above sea level, located in the Himalayas on the border between Nepal and China. Kanchenjunga is third highest, while Godwin Austen (K2) is second highest. 'Visuveus' appears to be a misspelling, possibly of Vesuvius which is not a major peak.

The Sahara Desert in northern Africa is the largest hot desert in the world, covering approximately 9.2 million square kilometers. It stretches across 11 countries including Egypt, Libya, and Algeria. The Kalahari, Thar, and Takla-Makan are significant deserts but much smaller in comparison.

Greenland is the largest island in the world, covering approximately 2,166,086 square kilometers. Australia is often mistakenly called an island but is actually classified as a continent because it sits on its own tectonic plate. Sri Lanka and Majuli (in India) are much smaller islands.

Mars has Olympus Mons, the tallest known mountain in the solar system at 21.9 km. Earth's Mount Everest is only 8.85 km tall. The Moon's highest peak is much smaller, and Pluto has mountains but not as tall as Olympus Mons.

Greenland is the world's largest island by area, covering about 2.16 million square kilometers. Australia is larger but is classified as a continent, not an island.

Greenland is the largest island in the world at approximately 2.16 million square kilometers. Australia is a continent, not an island.

Greenland is the world's largest island, covering 2,166,086 square kilometers. Australia (option A) is a continent, not an island. South America (option D) is also a continent, and the UK (option B) is much smaller. Australia is often confused as an island but is technically a continental landmass.

South China Mall in Dongguan, China, is the world's largest mall when measured by total floor area (leasable area under 6 million sq ft). The Dubai Mall is larger by gross leasable area but smaller in total area.
