The port is one of the busiest in the world by tonnage. Changi Airport's Jewel holds a 40 m indoor waterfall, the tallest of its kind. ## United States Third or fourth largest country in the world depending on how China's area is counted. It spans six standard time zones across the fifty states, from UTC-10 in Hawaii to UTC-5 on the east coast. Death Valley holds the highest reliably recorded air temperature on Earth, 56.7 °C in 1913, and is 86 m below sea level; Denali, 5,500 km away in Alaska, is 6,190 m. > Neutral facts only. Nothing here addresses politics, government, economics or which country is preferable in any respect — population is the one figure that dates, and it carries its year. ## Common questions ### Is Singapore bigger than United States?
