List and describe the different types of hydrothermal vents
What will be an ideal response?
Warm-water vents have water temperatures below 30°C (86°F) and generally emit water that is clear in color. White smokers have water temperatures from 30° to 350°C (86° to 662°F) and emit water that is white because of the presence of various light-colored compounds, including barium sulfide. Black smokers have water temperatures above 350°C (662°F) and emit water that is black because of the presence of dark-colored metal sulfides, including iron, nickel, copper, and zinc.
