The mid ocean ridge l.jpg
The mid ocean ridge

  • The mid-ocean ridge is a point in the middle of the ocean where plates are diverging

  • Moving apart

  • This is known as a central rift valley

  • Water seeps into the crack that forms

  • This water forces its way back to the surface through hydrothermal vents or deep-sea hot springs

What are black smokers l.jpg
What are black smokers?

  • The water coming from these vents is filled with minerals

  • mainly sulfides

  • The warm water cools when it hits the ocean

  • The minerals cool and solidify, depositing the minerals around the vent

  • Black smokers are one type of mineral deposits around hydrothermal vents


Slide5 l.jpg

The mineral deposits build up around the vents creating chimney-like structures

The smoke is a cloud of dense mineral particles


Is there any great importance to these smokers l.jpg

  • Life!

  • In this dark cold portion of the planet the “smokers” give life

  • The heat from the vents warms

  • The water is rich in nutrients and minerals

  • All types of life exists by the vents
