1: Who is NOAA?
They are the National Oceanic Atmospheric Administration and they study the geologic and biologic mysteries of the deep sea.
2: What is the mid-ocean ridge system? What happens there?
65,000km long series of sea floor spreading centers where new Earth is created.
3: How long/wide the is mid-ocean ridge system? Where is it located?
65,000 km long and 1,500 km wide and it is located in the Pacific Ocean
4: What type of plate boundary forms a mid-ocean ridge system? Explain.
It is a divergent plate boundary because two of Earth's crust pieces pull away frow each other.
5: Explain how ridges form:
Theres tension in the ocean crust where its getting pulled away. Then magma spews out.
6: What forms most of the ocean crust?
High ridges form a lot at the ocean crust.
7: How does hot lava respond to cold sea water? (Pillow Basalt)
It cools down and solidfies.
8: What is happening at the Juan de Fuca Ridge?
New crust is being created there.
9: What does the rate of spreading dictate?
It varies around places and it can be from 1-3 cm a year to 20-30 cm a year.
10:How hot can sea water be heated to at the mid-oceanic ridges?
400 degrees Celcius
11: Explain how HYDROTHERMAL Vents are formed:
Mineral laden water rises out of a crack of the crust boiling as a hot spring.
12: Why is the hot mineral water so important? What do they support?
It nourishes bizzare fauna, which only exists at hydrothermal vents.
13: What is chemosynthesis? How does it differ from photosynthesis?
It converts minerals to energy.
