hydrothermal vents
Storyboard Tekst
- hello my name bully i devoted my life to oceanography
- hydrothermal pressure will increase every 10 meters by one atmosphere.the average depth in a vent is 7,000 feet.
- sea water in hydrothermal vents can reach temperatures of 700* fahrenheit.
- bacteria in vents will get energy to produce sugars by getting them from chemicals and fluids.
- there is an organism that is named zooplankton there shrimp and they have adpated to living in extreme conditions by eating other bactiera.
- our father has only taught you a chunk of todays lesson, but now the fox brothers will teach you about the alvin exprloration.
- Like i stated previously bacteria and Archaea which is the base of the food chain .they do not use photosynthesis but they use chemosynthesis and make sugars from energy and chemicals in the hydrothermal vents.
- vents where discovered in 1977.
- we want to tell you about hydrothermal features, fun facts, and how they work.
- -down there in these vents there are black and white smoker.-white smokers are chimneys formed from deposits of barium,calcium and silicon which are all white substances.
- black smokers jets of particle-laden fluids. The particles are predominantly very fine-grained sulfide minerals formed when the hot hydrothermal fluids mix with near-freezing seawater
- if you ever wonder how vents are formed they actually happen when the earth's crust moves(tectonic plates). and they can last up to 10,000 years.
- precipitate are important to hydrothermal vents As they minerals precipitate, they form a solid structure onto the seabed around the venting fluid known as a vent chimney.
