Using their great stone tail or earthen claws, they can destroy almost anything in short order. The majority of their time is spent burrowing through the Plane of Earth devouring gems, minerals, and silicate life forms. On occasion, they are summoned to the Material Plane by evil (and foolish) spellcasters who usually live just long enough to regret their mistake. Elemental earth dragons are evil (perhaps the evilest of the elemental dragons in addition to being the strongest) and despise most other forms of life. They rarely associate with other creatures, though a few have been known to have dealings with the occasional earth elemental.
