Top 5 Natural Wonders of the World

5 Natural Wonders of the World With so many beautiful places on earth, a list of the top five natural wonders of the world is unlikely to create a consensus. This is our version of the natural wonders of the world which we think represent the best of what nature has to offer. 1. Sahara The Sahara is the world's largest hot desert covering most of Northern Africa, making it almost as large as the United States. The Sahara receives less than three inches of rain a year on average. Even in the Sahara's wettest areas, it may rain only twice a week and not rain again for years. 2. Mount Everest At 8,848 meters (29,029 ft), Mount Everest is the highest mountain on Earth. It is located on the border between Nepal and Tibet. The highest mountain in the world attracts climbers of all levels. Although other eight-thousanders such as K2 are much more difficult to climb, Mount Everest still has many inherent dangers such as altitude sickness, weather and wind. 3. Antarctica Antarctica, on average, is the coldest, driest, and windiest continent on the planet, and has the highest average elevation of all the continents. Although about 98% of Antarctica is covered by ice, it is technically a desert (the largest on earthSea life of Antarctica include penguins, blue whales, orcas, and seals.) with very little precipitation. 4. Great Barrier Reef The Great Barrier Reef is the largest system of coral reef in the world, stretching more than 3000 kilometers (1,900 miles). It is the only reef on Earth that can be seen from space and is the world's biggest single structure made by living organisms. The reef structure is composed of and built by billions of tiny organisms. 5. Serengeti The Serengeti ecosystem is located in northwestern Tanzania and extends to southwestern Kenya. The region hosts the largest mass movement of land mammals on the planet and one of the most breathtaking events in the animal kingdom.
