The word "Hydrothermal" is spelled as /ˌhaɪ.drəˈθɜːr.məl/. The first syllable is pronounced with a long "i" sound followed by "dro," which is pronounced with a hard "d" sound. The second syllable is pronounced with a "th" sound followed by "er," which is pronounced with a schwa sound. The third syllable is pronounced with a long "e" sound followed by "al," which is pronounced with a schwa sound. This word is commonly used to describe geological processes involving heated water and rock.
Hydrothermal is an adjective that pertains to the conditions or processes involving heated water or steam. The term is derived from combining the Greek words "hydro" meaning water, and "thermos" meaning heat. Hydrothermal phenomena occur in various natural settings, including oceans, volcanic areas, and deep within the Earth's crust.
When referring to hydrothermal vents, the term describes underwater geysers or hot springs found along tectonic plate boundaries, often at great depths in the ocean. These vents release superheated water rich in minerals and gases, such as hydrogen sulfide. Hydrothermal vents support unique ecosystems where various organisms thrive despite extreme temperatures, darkness, and high pressure.
In geology, hydrothermal activity involves the circulation of hot fluids through rocks and minerals, leading to alteration or formation of new minerals. This process commonly occurs in areas with magma activity and can produce valuable ore deposits, such as gold, silver, or copper. Hydrothermal systems are also associated with geothermal energy, where naturally heated water or steam is used to generate electricity.
In chemistry, hydrothermal synthesis describes the process of creating crystalline materials using a high-pressure, high-temperature environment. By placing substances in a closed container with water or another solvent and subjecting them to specific conditions, scientists can induce the formation of unique crystals with desired properties.
Overall, the term hydrothermal encompasses a broad range of natural processes and phenomena involving heated water or steam, from deep-sea ecosystems to mineral deposition and laboratory synthesis.
Of or pert. to hot water-applied to the action of heated waters in dissolving, redepositing, and otherwise producing mineral changes within the crust of the globe.

The word "hydrothermal" is formed by combining two Greek roots: "hydro", meaning water, and "thermos", meaning heat.
"Hydro" (ὕδωρ) is derived from the Greek word "hudōr" (ὕδωρ) meaning water. It is commonly used in scientific terms related to water, such as "hydrant" and "hydrate".
"Thermos" (θερμός) is derived from the Greek word "thermós" (θερμός), meaning hot. It is used in scientific terms related to heat and temperature, such as "thermometer" and "thermostat".
When combined, "hydrothermal" refers to the process or condition involving heated water. It is often used in geology to describe mineral formation or other geological processes that occur due to the interaction of hot water with rocks or minerals.
