1: Who is NOAA?
a1: The National Oceanic and Atmospheric Administration.
2: What is the mid-ocean ridge system? What happens there?
a2: a series of ocean floor spreading centers where new earth is created.
3: How long/wide the is mid-ocean ridge system? Where is it located?
a3: It is 65,000 km and at the sea floor.
4: What type of plate boundary forms a mid-ocean ridge system? Explain.
a4: Divergent Boundaries form a mid-ocean ridge system. They are areas that the sea floor separates.
5: Explain how ridges form:
a5: When the oceanic plates are torn apart.
6: What forms most of the ocean crust?
a6: The separation of the oceanic plates.
7: How does hot lava respond to cold sea water? (Pillow Basalt)
a7: It pushes out through its hardened shell that forms as soon as it comes in contact with the cold sea water.
8: What is happening at the Juan de Fuca Ridge?
a8: 6m with of new crust is made every 100 years.
9: What does the rate of spreading dictate?
a9: The height and steepness of the ridge.
10: How hot can sea water be heated to at the mid-oceanic ridges?
a10: 400 degrees celcies .
11: Explain how HYDROTHERMAL Vents are formed:
a11: Sea water is heated by the magma in fissures in the ridge and dissolve minerals that then flow up to form the vents.
12: Why is the hot mineral water so important? What do they support?
a12: They feed the tube worms at the hydrothermal vents.
13: What is chemosynthesis? How does it differ from photosynthesis?
a13: It is the process of living creatures taking minerals and converting them into energy. it does not use sun light.
