The largest cave in the world

How big is the largest cave in the world? How big is it? Take a look at the relevant information I have collected for you.

The world’s largest natural cave can accommodate the earth’s 7.2 billion people.

It is said that the world is so big that it is full of wonders. There is the world’s largest cave not far from our country. It Phong Nha Chebang National Park in Vietnam is the most mysterious cave in the world and the largest cave in the world.

Because the cave is so big, it would take a whole day to even walk to the entrance. There once was an expedition team from Britain that came here to investigate. But they had to turn back because they encountered huge calcite walls and floods.

Although this expedition team did not complete the entire journey. However, after their exploration, they were determined to have discovered the largest natural cave in the world.

According to surveys, there is the largest cave here, with a length of 5,000 meters, a width of 150 meters, and a height of more than 200 meters, equivalent to a 60-story high-rise building. Someone once did a simulation experiment, that is, if 7.2 billion people in the world were put together, the height would only be 788 meters. At this rate, the cave is so big that it can completely accommodate everyone in the world.

This cave is so big and it is also a natural cave, which is really rare. It is precisely for this reason that Phong Nha Chebang National Park was rated as a World Natural Heritage in 2003, and it has also become a famous tourist attraction in Vietnam.

But one thing to note is: if you want to enter it, the physical requirements for tourists are relatively high, so you still have to do what you can! Therefore, only about 320 tourists can enter it every year. The mystery in the cave!

The ten most beautiful natural caves in the world

A natural cave refers to a naturally formed underground passage or space that can be entered. It may be formed by water Due to the erosion of water, or the weathering of other external forces such as wind and microorganisms, many natural caves are formed in limestone areas and are called karst caves (stalactite caves). There is also a similar terrain called a stone shed.

1. Greenland Ice Shield

Cave explorers used ropes to penetrate 300 feet (approximately 90 meters) into the Greenland Ice Shield. Glacial caves like this are formed when seasonal meltwater or geothermal vents carve cracks and channels into the ice shield. Because they are made of ice, glacier caves are in an extremely unstable state, posing unique challenges for explorers.

2. Lava Beds National Monument, United States

Lava tube caves like this are found all over the world. This unique underground structure was formed by long periods of lava flow. As lava flows through the channel, the overflow forms natural banks on either side. The banks eventually join together and solidify to form a canopy.

Just as winter water continues to flow beneath its ice cap, so does lava continue to flow beneath its canopy. When the lava flow at the source stops, the remaining lava flows all the way to the end, forming a hollow tube-like structure. This tubular structure usually has a large space within which the explorer can walk.

3. Limestone Cave

The entrance to the limestone cave in Chilean Patagonia was formed under the influence of water for a long time, so it is also called "water and water". The art of time?. Limestone is a soluble rock, and slow-moving water acted as a chisel over hundreds of thousands of years. Geologists call this structure a cave.

4. Greenland Glacier Caves

The changing colors and shapes are more like a spiral galaxy than a component of a cave. The otherworldly contours of this large icehouse are formed by the heat of geothermal hot springs.

5. Chinese Reed Flute Cave

Bathed in blue-purple light, China's Reed Flute Cave gives people the impression that it is like the filming scene of a science fiction movie. This karst landform was formed by an underground river more than 500,000 years ago. It is highly accessible and is one of the most environmentally friendly tourist attractions in the area. During World War II, Reed Flute Rock was used as an air raid shelter.

6. Tequila Cave, United States

The Tequila Cave in Carlsbad Caverns National Park, New Mexico, USA. The stalagmites in the cave are surrounded by crystal-clear water. Once unknown, the cave gained worldwide fame in 1986, when cave explorers broke through a closed passage and discovered numerous tunnels that could be walked through. Since then, explorers have mapped more than 100 miles (160 kilometers) of tunnels. Agave Cave has become the third longest cave in the United States and the fifth longest cave in the world.

7. The tower-like structure of Agave Cave

The tower-like structure of Agave Cave is about 50 feet (approximately 15 meters) high. A cave explorer looks dwarfed against it. The famous Agave Cave is located in Carlsbad Caverns National Park in New Mexico. It attracts a large number of explorers from all over the world to explore here every year.

8. Calcite deposits

Rare calcite deposits, shaped like wheat flakes, were found deep on the walls of the Agave Cave. Scientists believe that this corrugated structure, called "leaf lines," is formed by the deposition of calcite during repeated rises and falls in water levels.

9. Cave Pearls

The mineral deposits in caves can show surprising shapes, such as these chocolate-like "cave pearls" in the picture. This unique spherical structure forms in cave pools from layers of calcite slowly deposited around a grain of sand or dirt.

10. Diebold Cave, United States

The Diebold Cave in Florida is located 250 feet (approximately 76 meters) underground. The diver in the picture is facing a Exploring flooded caverns. Named after the original owner of the area, Diebold's Cave is located at the Sand Hill Boy Scout Camp near Brooksville, Florida.
