How it's used
Refers specifically to the space beneath the surface of the earth, often used when discussing infrastructure like tunnels or subway lines. It carries a sense of being hidden or buried, distinct from the more abstract or literary term 地下 which can also imply basement levels or illicit activities.
Examples
This tunnel was built underground.
Do you know what creatures are living underground?

Common mistake
Avoid using it to describe a basement or a subway station, where 地下 is the standard term. 地底 emphasizes the physical layer of soil or rock rather than a building level.
