World Geographical Records

The Seven Natural Wonders of the World include Grand Canyon, Mount Everest, Victoria Falls, Great Barrier Reef, Harbor of Rio de Janeiro, Paricutin Volcano, and Aurora Borealis. Polar Ice Caps are not among these designated wonders, making C the correct choice as the option that doesn't belong.

The Strait of Hormuz is the narrow passage between the Persian Gulf and the Gulf of Oman, connecting these waters to the Arabian Sea. It is one of the world's most strategically important chokepoints for oil transport, with about one-fifth of global oil consumption passing through it daily.

Greenland is the world's largest island by area, covering about 2,166,000 square kilometers. Australia is technically a continent, not an island, despite being surrounded by water. Great Britain and Iceland are significantly smaller than Greenland. This geographical distinction is important in understanding Earth's landmasses.

The Baltoro Glacier in the Karakoram range of Pakistan is approximately 62 kilometers long, making it one of the world's longest non-polar glaciers. Option A (14 km) is far too short. Option B (30 km) underestimates its length. Option D (175 km) is exaggerated and would make it longer than most glaciers on Earth.

All statements are true about Burj Khalifa: it is the tallest building in the world at 828 meters, the tallest free-standing structure, and has elevators with the longest travel distance. These are some of its many world records.

Hirakud Dam in Odisha is the world's largest earthen dam. It stretches 25.8 km across the Mahanadi River and has a reservoir capacity of 8.1 cubic km. 'Earthen dam' refers to dams built primarily from compacted earth materials.

Nagarjuna Sagar Dam, built across the Krishna River in Telangana, is the world's largest masonry dam. Completed in 1967, it stands 124 meters tall and creates a large reservoir supporting irrigation and hydroelectric power generation.

Alaska is by far the largest state in the United States by land area, covering about 663,300 square miles. It's more than twice the size of Texas, the second-largest state. Alabama, Arizona, and Arkansas are among the smaller states. Alaska was purchased from Russia in 1867 and became the 49th state in 1959.

The Weihe Grand Bridge in China is the longest bridge in the world at 164.8 km (102.4 miles). It is a high-speed railway bridge completed in 2010. The Bang Na Expressway in Thailand was previously the world's longest highway bridge but is shorter than Weihe.

Iguacu Falls (Iguazu) on the Brazil-Argentina border is recognized as the widest waterfall system in the world, spanning approximately 2.7 kilometers. Angel Falls is the tallest by height, and Victoria Falls is also very wide but not as wide as Iguacu.

The Nile River in Africa is approximately 6,650 km long and is traditionally considered the longest river in the world, though some recent measurements suggest the Amazon may be slightly longer. The Mississippi (not 'mississipi') and Yellow River are significantly shorter.

Burj Khalifa in Dubai is the world's tallest man-made structure at 828 meters (2,717 feet), completed in 2010. It surpassed Taipei 101 and has held the record since. The Eiffel Tower (324m), World Trade Center (417m/420m original), and Qutab Minar (73m) are significant structures but not record holders.
