🕳️ Cave
Exploring the wonder of a cave!
A Cave is a hollow, natural space underground or inside a mountain.
🌍 What Is a Cave?
A cave is a natural hollow space underground or in the side of a hill or cliff. Many caves form in limestone, a rock that slowly dissolves in rainwater. Over thousands of years, the water carves out tunnels and rooms, and as drips of water dry, they leave behind tiny bits of rock that build up into stalactites and stalagmites.
🌟 Fun Facts about Cave
- Caves can form over thousands of years as water slowly wears away soft rock.
- Some caves have amazing rock formations called stalactites (hanging down) and stalagmites (growing up).
- Bats often make their homes in the cool, dark shelter of caves.
- Some caves are so large that entire rooms and tunnels can fit inside them.
🔎 Where to See a Cave
Some famous caves, such as Mammoth Cave in the USA and the Waitomo Caves in New Zealand, where glowworms light up the ceiling, have safe paths and guided tours. Explorers who study caves are called speleologists. Never go into a cave without an adult and a guide, because caves can be dark, slippery and easy to get lost in.
