In what materials do caves form?
Costa Rican caves are found in karstic regions. Karstic physiographic is found in limestone rock, a sedimentary rock which is naturally dissolved by “acid rain”, thus synthesizing carbonic acid (diluted). Around the world, it’s on limestone where we find more caves, being these largest and most spectacular. Never the lees, there are caves formed in other type of rocks, such as sandstone, sea-side caves, which open in any type of rock, and volcanic lava formed caves, known as “lava tubes”.
