Mid-Ocean Ridges
1: Who is NOAA?
National Oceanic and Atmospheric Administration
2: What is the mid-ocean ridge system? What happens there?
It's new ocean crust of the North America. They explore things like volcanoes.
3: How long/wide the is mid-ocean ridge system? Where is it located?
The Mid-ocean ridge is about 65 ,000 km long and 1,500 km wide.It's located in the NorthWedt of the US.
4: What type of plate boundary forms a mid-ocean ridge system? Explain.
Divergent Plate Boundary; plates pull away from each other and new sea floor is created.
5: Explain how ridges form:
It starts with Divergence plate boundary then the crust rises to form a high ridge on the sea floor.
6: What forms most of the ocean crust?
Basalt and granite.
7: How does hot lava respond to cold sea water? (Pillow Basalt)
It starts to cool then the hot lava turns solid.
8: What is happening at the Juan de Fuca Ridge?
The spreading makes the width of 6 m of new crust every 100 years.
9: What does the rate of spreading dictate?
It influences the topography of the ridges.
10: How hot can sea water be heated to at the mid-oceanic ridges?
It can be heated 400°C at the Mid-Oceanic Ridge.
11: Explain how HYDROTHERMAL Vents are formed:
The heated water dissolves minerals and they then are carried. The thick water then comes out of the crust.
12: Why is the hot mineral water so important? What do they support?
Its important because it keeps animals and plants living. They support by giving energy and materials.
13: What is chemosynthesis? How does it differ from photosynthesis?
Chemosynthesis converts minerals to energy. It is different from photosynthesis because photosynthesis converts sunlight into energy.
