A cave is a naturally occurring underground space which is so large that a human can easily enter in it. There are many types of caves such as rock shelters, sea caves and grottos existing on earth and some of these caves are very deep.
Infact some caves in the world are so deep that they extend for thousands of meters and have been penetrated by many researchers and groups of excavators. The process of exploring a cave for research or science is known as caving or potholing. Through these techniques, the deepest caves in the world have been found out.
