There are countless beautiful and magical places on the earth, and recently the American "touropia" website took stock of a list of the world's ten natural wonders, believing that "they represent the best side of nature". A list is unlikely to reach a consensus, so let's see if there are any of the ten natural wonders of the world in your mind!

Sahara
（sahara）
The Sahara Desert is the largest hot desert in the world, covering much of North Africa and almost the size of the United States. Contrary to popular belief, large sand dunes (called ergs) make up only a small part of the Sahara Desert. Most deserts are made up of barren, hard, rocky plateaus with very little sand. The average annual precipitation in the Sahara is only a few tens of millimeters. Even in the wettest areas of the Sahara, it is possible to rain only twice a week and not again for years to come.
Halong Bay
（ha long bay）
Halong Bay is located in northern Vietnam and has a 120 km long coastline. The bay features thousands of islands, each topped with lush jungle vegetation, forming a spectacular seascape of limestone columns. Some of the islands are hollow with huge caves, while others include lakes and some villages that support fishermen's floating.

Everest
（mount everest）
Mount Everest, at 8,848.86 meters above sea level, is the highest mountain on Earth and is located on the border between Nepal and Tibet. The world's tallest mountain attracts many climbers. Mount Everest is difficult to climb and has many inherent dangers such as altitude sickness, weather and wind. People who die during the climb are usually left behind on the mountain, and it's not uncommon to find bodies near the standard climbing route.
Antarctica
（antarctica）
Antarctica is the coldest, driest and windiest continent on Earth, with the highest average elevation of any continent. Although 98% of Antarctica is covered in snow and ice, it is technically a wasteland with very little precipitation. Antarctica is colder than the Arctic because much of Antarctica is more than 3 km above sea level, and the Arctic Ocean covers the Arctic strip, allowing the temperature of the ocean to be transmitted through the ice strip. Antarctica's marine life includes penguins, blue whales, orcas and seals.

Great barrier reef
（great barrier reef）
The Great Barrier Reef is the largest coral reef system in the world, stretching for more than 3,000 kilometers. It is the only coral reef on Earth that can be seen from space and the largest single structure of life in the world, made up and built of billions of tiny creatures. The Great Barrier Reef is also home to many wildlife, including green sea turtles, dolphins, whales, sea snakes and clownfish.
Grand canyon
（grand canyon）
Located in northern Arizona, the Grand Canyon is one of the most famous tourist attractions in the United States. The Colorado River has been carved for millions of years, and the canyon is more than 1.6 kilometers deep and 446 kilometers long. The Grand Canyon is not the deepest or longest canyon in the world, but its overwhelming scale and intricate, colorful scenery offer visitors a spectacular spectacle that is unparalleled in the world.

Iguazu Falls
（iguazu falls）
The Iguazu Falls is one of the world's greatest natural wonders, located on the border between Brazil and Argentina. The waterfall system includes 275 waterfalls along the Iguazu River. The height of most waterfalls is about 64 meters. The most impressive of these is the Devil's Throat Waterfall, which is u-shaped and is 82 meters high, 150 meters wide and 700 meters long.
Amazon
（amazon）
The Amazon is the largest river in the world, with a total flow of about one-fifth of the world's total flow. The river has more than 3,000 species of identified fish, and new species are still being discovered. The Amazon rainforest represents more than half of the existing rainforests on Earth. As the largest rainforest, it has unparalleled biodiversity. One-tenth of the world's known species live in the Amazon rainforest.

Galapagos islands
（galapagos islands）
The Galapagos Islands are a small archipelago of volcanic archipelagos in Ecuador in the eastern Pacific Ocean. The islands are very remote and isolated, located about 1,000 kilometers west of the South American continent. The archipelago is world-famous for its unique island ecosystem, and Darwin's theory of natural selection was inspired here. To see these amazing sights and wildlife, it's best to take a boat trip. Booking a cruise in the Galapagos Islands is usually the most convenient, but it's also more expensive. There are also many companies that can book trips to the Galapagos Islands from Puerto Ayora, Guayaquil or Quito.
Serengeti
（serengeti）
The Serengeti ecosystem is located in northwestern Tanzania and extends all the way to southwestern Kenya. The region, home to the largest mass migration of land mammals on Earth, is one of the most breathtaking events in the Animal Kingdom. The African Safari follows 1 million wildebeests and 200,000 zebras on a 500-kilometer round-trip journey from southern Serengeti in Tanzania to the northern edge of kenya's Masai Mara National Reserve. The Great Migration is probably Africa's most spectacular nomadic wonder and the most extraordinary natural wonder in the world.
