Most are fomed in limestone uplands by dissolution of the rock by ground-water, so they form drains taking the rain falling on the hills to springs in the valleys. That's what they do on Earth!
how do caves form
the moon is not like earth. so there are not any underground caves. it a solid!! duh. Updated answer Since the moon is considered to be part of the Earth and there are caves on Earth. Why cant there be caves on the moon.
you don't
Well, depending on what type of cave we are talking about here (Underwater caves, Underground caves, Mountain range caves, Man-made caves) you can likely derive your own conclusion with some simple research. Caves, in general, do not really belong to any specific Biome. All biomes have some kind of cave somewhere on earth. There are caves on every corner of the earth so the answer to your question is that there are caves in every Biome.
They are found in caves or deep in the earth.

The softest place on Earth is considered to be the Belum Caves in India, which are made of limestone and shale rock formations. These caves have unique geological features that make the surfaces soft to the touch.
Speleology, the study of caves, is like other geological sciences an "earth" science.
