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 Dnieper River (Dnipro) flows southward through both Belarus and Ukraine, forming part of the border between the two countries. It is one of the major rivers of Eastern Europe, approximately 2,200 km long. The Sava flows through Slovenia and Croatia, the Ural forms the Russia-Kazakhstan border, and the Rhine flows through Western Europe.

The Leshan Giant Buddha is in Sichuan Province, China, not Tibet. Carved into a cliff face, it's the largest carved stone Buddha in the world at 71 meters tall. Built during the Tang Dynasty (713-803 AD), it's a UNESCO World Heritage Site.

A landlocked sea is a body of water entirely enclosed by land with no direct connection to the ocean. The Aral Sea (between Kazakhstan and Uzbekistan) is the most famous example, though it has severely shrunk due to water diversion. The Timor Sea, Arafura Sea, and North China Sea are all connected to oceans.

Haiti is located in the Caribbean Sea, on the island of Hispaniola which it shares with the Dominican Republic. The Mediterranean Sea is between Europe and Africa, the Red Sea separates Africa from the Arabian Peninsula, and the Bismarck Sea is near Papua New Guinea in the Pacific Ocean.
