Question

Describe the hydrothermal vent ecosystem?

Answer 1

Science Dictionary
hydrothermal vent
A fissure on the floor of a sea out of which flows water that has been heated by underlying magma. The water can be as hot as 400°C (752°F) and usually contains dissolved minerals that precipitate out of it upon contact with the colder seawater, building a stack of minerals, or chimney . Hydrothermal vents form an ecosystem for microbes and animals, such as tubeworms, giant clams, and blind shrimp, that can withstand the hostile environment. ◇ The hottest hydrothermal vents are called black smokers because they spew iron and sulfide which combine to form iron monosulfide, a black compound.

Answer 2

Hydrothermal vents are the result of seawater percolating down through fissures in the ocean crust in the vicinity of spreading centers or subduction zones (places on Earth where two tectonic plates move away or towards one another). The cold seawater is heated by hot magma and reemerges to form the vents.
