Caves – Mysterious and Intriguing

The Seasons video

Have you ever explored a cave? Caves are dark and interesting. You might imagine animals or people that have been in the cave before you. But have you ever wondered how a cave is made? Caves are usually made when water runs over soft rock, such as limestone.

The acid in the water slowly eats away the limestone, making a hole. The hole gets larger and larger. If the water finds a new path, the cave is left dry.

Caves can also be created when hot lava melts rocks, forming holes. Occasionally, the ceiling of a cave collapses, leaving a huge room or cavern. Tidal waters along a coast can carve out caves.
