Vent Basics:
Define the following (Make sure to include photos)
* Explain the process of a BLACK SMOKER
~ The black smoker is a hydrothermal fluid that is so hot (350-400degrees Celsius) and it can melt metals. The process of black smoker is that the fluid carries dissolved from beneath the ocean floor and mixes with the sea water. Then the metals combine with sulfur to make small black particles which look like smoke.
Vent Boiling Points:
* Explain why the boiling point of water changes with depth in the ocean
~ Boiling point of water changes with depth in the ocean, because the deep you go the more increase of pressure. Such as being at sea level the pressure equals one atmosphere.
Vent Chemistry:
* Explain how the water chemistry changes in the hydrothermal vent system
~ Water chemistry changes in the hydrothermal vent system, because the hydrothermal fluids mix with cold rich oxygen sea-water (then creates black mineral particles like smoke).
Vents Around the World:
* Where can hydrothermal vents be found? Give a few examples.
~ Hydrothermal vents are found around Juan de Fuca, Broken Spur, Mariana's Trough, Kairei, Edmond, and more. Hydrothermal vents are found where there are hot/ molten rocks (magma) under the ocean floor.
Vent Life:
*Name some of the critters found around hydrothermal vent systems
~ Critters found around the hydrothermal vents are octopus, tubeworms, dandelions, crabs, clams, and more.
Tubeworm Anatomy:
* Describe the tubeworm anatomy. Explain the symbiotic relationships that are found within tubeworms
~ The tubeworm anatomy shows and describes about the tubeworm's plume, muscle, cavity, and worm tube. The symbiotic relationships such as the plume's blood that transports oxygen, hydrogen sulfide, and carbon dioxide from the water to the bacteria in the cavity. The cavity is packed with bacteria, because it sends sugar by chemosynthesis to use as food.
Chemosynthesis:
* Explain the different between photosynthesis and chemosynthesis
~ The differences between photosynthesis and chemosynthesis is that, chemosynthesis gets their energy from chemicals in hydrothermal fluid.
