This is the scientific study of caves. The word speleology comes from the Latin word “speleum” and the Greek word “spelaion,” both of which mean “cave.” The ending, “ology,” means “the study of.”
Someone who studies caves is called a speleologist (spee-lee-AWL-oh-gist). A speleologist might study the rock that caves are made of or how caves form and why. They can also study the organisms that live in those caves. Some even study caves to find out more about the history of the Earth.
