Detailed explanation-1: -Hydrothermal vents form deep in the ocean when iron-rich magma is released from openings on the seafloor. These vents spew extremely hot water (400oC) mixed with methane and sulfur.
Detailed explanation-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.
Detailed explanation-3: -Hydrothermal vents are naturally forming structures found in the ocean. They usually occur on divergent plate boundaries, where tectonic plates are moving apart. The vents expel a fluid that was heated to extreme temperatures when seeping through the Earth’s crust from the ocean.
Detailed explanation-4: -Hydrothermal vents in the deep ocean typically form along the mid-ocean ridges, such as the East Pacific Rise and the Mid-Atlantic Ridge. These are locations where two tectonic plates are diverging and new crust is being formed.
