Discuss how hydrothermal vents are believed to form. What will be an ideal response?
It is believed that water descends through fissures and cracks in the ridge floor until it
comes into contact with very hot rocks associated with active seafloor spreading.
There the superheated, chemically active water dissolves minerals and gases and
escapes upward through the vents by convection.
