Introduction to Mid-Ocean Ridges:
1: Who is NOAA? NOAA stands for National Oceanic & Atmospheric Administration. Is a leader that explore every sea to find new things that is geologic and biologic mysteries.
2: What is the mid-ocean ridge system? What happens there? Is also called the Ring of Fire and what is does it forms longest and largest mountain range on the earth.
3: How long/wide the is mid-ocean ridge system? Where is it located? Is between the continents North America and Asia and is more than 65,000 kilometers long and 1,500 km wide.
4: What type of plate boundary forms a mid-ocean ridge system? Explain. The type of plate boundary is a Divergent boundary because they are torn apart.
5: Explain how ridges form:
6: What forms most of the ocean crust? When the earth's crust are pull away from each other a new sea floor is created in the gap between them. The older crust is recycled back into the mantle on the globe where the plates collide.
7: How does hot lava respond to cold sea water? (Pillow Basalt) The outer skin flows solidfies while interior remains molten and keeps moving.
8: What is happening at the Juan de Fuca Ridge? When a crust is broken and pushed away by continued divergence and volcanism, oceans form and widen slow. So with Juan de Fuca ridge is creating and average width of 6 cm of new crust every 100 years.
9: What does the rate of spreading dictate? Some spreads very slowly no more than 1-3 cm per year while some others ones spreads at the rate 10-20 cm per year.
10: How hot can sea water be heated to at the mid-oceanic ridges? Since the mid-ocean ridges are laced and intruded by magma the seawater oceanic crust becomes very hot as much as 400 celcius
11: Explain how HYDROTHERMAL Vents are formed: It is formed when the mineral laden water come back out of the crust and it boils into the bottom of the sea through ocean floor hot springs and scattered along the rift valley.
12: Why is the hot mineral water so important? What do they support? The hot mineral water nourishes a bizarre fauna that only exist only at hydrothermal vents.
13: What is chemosynthesis? How does it differ from photosynthesis? Is a organisms use to produce energy. For the photosynthesis it doesn't use sunlight like always but uses the energy of a hot chemical which seep up from the earth's crust.
