Answer 1

seawater seeps into the ocean floor through cracks in the crust

Explanation:

At a hydrothermal vent, seawater seeps into the ocean floor through cracks in the crust.

Most hydrothermal vents are zones of mineralization.

• A hydrothermal vent is made up of fissures that percolates deep into the crust near a spreading center or subduction zone.
• The percolating water is heated by magma as it approaches it and it re-emerges in vents.
• These vents are usually located where volcanic activities are predominant.
• One common type is a black smoker.
• Some common minerals found near such vents are manganese, copper, iron etc.
