The next two wonders of the natural world are mountains. Paricutin is a volcano in Mexico that is nearly 3000 metres high. The reason that this volcano has been voted a natural wonder is because people actually watched its birth and growth in the 1940s! The volcano’s last eruption was in 1952. Then, of course, the world’s tallest mountain’ Mt. Everest, should of course also be added to the list of natural wonders. Located between Tibet and Nepal, this mountain reaches to a height of more than 8,800 meters above sea level.
