hydrothermalism

Example:Scientific research on hydrothermal systems focuses on understanding the role of these dynamics in the formation of mineral deposits and in providing habitats for unique deep-sea ecosystems.

Definition:A combination of geologic and hydrodynamic processes involving the flow and discharge of hot fluids into the surrounding environment.

Example:Exploration of hydrothermal vents has revealed ecosystems fueled by chemosynthesis rather than photosynthesis, including species such as giant tube worms and giant clams.

Definition:Natural fissures on the seafloor from which geothermally heated water (sometimes richly laden with dissolved minerals and gases) is discharged.
