A cave is a hollow space below the ground or inside a mountain or other elevated landform.
Wind and waves can form caves along the shoreline in soft rock formations. Wind and rain can erode limestone that lay under a hard layer of rock, forming a cave. Freeze-thaw erosion can also lead to cave formation. The presence of groundwater can dissolve limestone deposits, forming caves underground. If the top of a cave is covered with a hard rock layer, the cave may last for a long period of time.
However, if the top of a cave is limestone, it may eventually weaken from exposure to water and cause the cave to collapse. Carbonic acid in groundwater and organic acids from the soil are often present to help dissolve limestone and form caverns underground. In some cases, sulfuric acid may be present in the groundwater, created from sulfuric gases rising from oil deposits below.
Lava from volcanic activity can also form caves and other openings in the ground. As lava flows, the surface can cool and harden. Inside this form, the lava may still be hot and drain away, creating a tube or other form. Later this may be covered by sediment and remain underground.
A cave is a hollow space large enough to allow a person to enter by walking or crawling. The largest caves have hundreds of miles of passages underground.
Caves are found all over the world where soft rock formations have been exposed to weather, waves or groundwater.

The longest known underwater cave in the world, called Sistema Ox Bel Ha, is found in Quintana Roo, Mexico with 160 miles of surveyed passages.
