Introduction to Mid-Ocean Ridges:
1: Who is NOAA?
National Oceanic and Atmospheric Administration
2: What is the mid-ocean ridge system? What happens there?
-New oceanic crust North American; Ring of fire is the most important system of mid ocean ridges.These are plate boundaries where the plates are pulling away from each other. They pull away and new magma fills the space in between. Over millions of years it cause a lot of new sea bed.
3: How long/wide the is mid-ocean ridge system? Where is it located?
This system is about 65 ,000 km long, 1, 500 km wide . Located at the Northwest of the United States.
4: What type of plate boundary forms a mid-ocean ridge system? Explain.
-Divergent: plates move away from each other.
5: Explain how ridges form:
The Ocean ridge was formed through the process of tectonic plate movement which forces lava through the created cracks and when the lava cooled it forms the ridge. Ocean ridges are formed from the uplift of newly formed oceanic crust by rising magma.
6: What forms most of the ocean crust?
Granite and Basalt
7: How does hot lava respond to cold sea water? (Pillow Basalt)
The thermal response; when hot lava respond with cold sea water it will turns into a solid
8: What is happening at the Juan de Fuca Ridge?
9: What does the rate of spreading dictate?
It will influences the topography of the ridge.
10: How hot can sea water be heated to at the mid-oceanic ridges?
400° C at Mid- Oceanic ridges
11: Explain how HYDROTHERMAL Vents are formed:
The earth's crust move and create cracks. Water from the sea will then sip through the cracks and find its way to molten rock or magma. The heater is then heated and finds its way out back it the sea floor.
12: Why is the hot mineral water so important? What do they support?
Minerals and it keeps animals and plants alive. It provides energy and materials.
13: What is chemosynthesis? How does it differ from photosynthesis?
Chemosynthesis is an alternate way to generate energy and make sugars to photosynthesis. Photosynthesis occurs in plants and some bacteria, wherever there is sufficient sunlight – on land, in shallow water, even inside and below clear ice. Chemosynthesis is the use of energy released by inorganic chemical reactions to produce food.
