The NOAA is the National Oceanic and Atmospheric Administration. This is so that you can explore every sea and find new things that other people have never seen before whether it geologic or biologic mysteries.
What type of plate boundary forms a Mid-Ocean ridge system?
The type of plate boundary that forms a mid-ocean ridge system is a Divergent Plate, because when you have two pieces of the crust of the earth that are pulling away this is making new sea floor. So then the old part of the earths crust gets thrown right back to the mantle where then the plates will push together.
How does hot lava respond to cold sea water? (Pillow Basalt)
The outer part of the lava flow solidflies instantly, when the middle stays molten and decides to keep on moving. This makes the surface of the basalt distort into little bumpy pillows
How hot can seawater be heated to at the mid- ocanic ridges?
The sea water oceanic cust can become really hot! As much as 400celcius.
What is the mid-ocean ridge system ? What happens there?
The Mid Ocean Ridge System is a term for an underwater mountain system that consists of various mountain ranges, that have either a valley known as a rift which runs along its spine which is then caused by the forming of plate tectonics.However it causes the largest and longest mountain range on the earth.
Explain How Ridges Form...
Ridges are formed when the ocean floor plates on the earths crust are pushed apart to then allow the magma to get through.
What is hapening at the Juan de Fuca Ridge?
The tectonic plates that are generated from this ridge, they are now subucting under the northerly portion of the western plate side of the North american plate at the Cascadia subduction zone.
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.
What is chemosynthesis? How does it differ from photosynthesis?
Is the biological conversion of one or more carbon molecules certain microbes create energythrough the chemicals that emerge from the hydrothermal vents.
How long/ Wide is the Mid-Ocean ridge system, and where is it located?
The mid ocean ridge is 65,000 K long and its width is 1,500. It is located between continents and has the longest and largest mountain system.
What forms most of the Ocean Crust?
What forms most of the Oceanic Crust is mostly just a mixture of mafic rocks and the sima which is rich in iron and also magnesium.
What does the rate of spreading dictate?
The rate of spreading influences topography, slow growth produces irregular topography and is often narrow.
Why is the hot mineral water so important? What do they support?
The hot mineral water is important because the water nourishes a fauna that is only found at the vents of hydrothermal.
