Hydrothermal+Vents8

__Hydrothermal Vents__ **Its amazing that some parts of the ocean can be up to 300F, this is because of hydrothermal vents. I can't belive that it all starts off with cold water(34-37F). If you get to the bottom of the ocean(20,000 ft down) there can sometimes be cracks there, down those cracks are hot rocks. When the two items collide they become hot water. This hot water then flows out of the cracks for animals there. Scientist were surprised in 1977 when they found a large amount of animals around the hydrothermal vent, as they are deadly for most organisms.** **-**

**I thought it was good that they definded what "cold" was in the second paragraph as 34-37F. I was amazed that the hydrothermal vents were deadly for most organisms when the scientists found a large group of them near the vents. I can't believe that the heat from the rocks and the coldness of the water can form 300F water, espically because animals like that warmth. Its so cool that the organisms that like the vents change the bacteria into food and energy. I wo****nder what animals can survive the vents, Hydrothermal vent crab, Giant tubeworm, and Hydrothermal vent squat lobster are some of the animals.** **I wonder how the cracks form on the floor of the ocean, I have not found the answer yet!!**
