Which of the mid ocean ridges has the fastest spreading rate?

A typical rate of seafloor spreading in the Atlantic Ocean?
The typical rates of seafloor spreading is 5 centimeters per year. Seafloor spreading is a process that occurs at mid ocean ridges.
Where is the rate of geothermal heat flow the greatest?
Along mid-ocean ridges.
New ocean floor is constantly being produced in the process known as?
There are three processes that add material to the ocean floor: Sedimentation, and Vulcanism. Sedimentation is usually caused by skeletons of sea animals falling to the ocean floor. It can be argued that this is not new material but only recycled materials. But some of the remains are calcium or other deposits that are added from land based run off. Silt deposits also run into the ocean floor from the land, Vulcanism results from shifts in the ocean mantle with new material coming from deeper in the earth and spouting through volcanoes or emerging as new ocean floor at the rising edges of the tectonic plates.
How do you calculate the rate of seafloor spreading?
rate of spreading for stripe = width of stripe / time duration If a magnetic strips is 60 km wide and formed over 2 million years, then the rate at which spreading formed the was 30 km/m.y. The rate is equivalent to 3 cm/year. Spreading added an equal width of oceanic crust to a plate on the other side of the mid-ocean ridge, so the total rate of spreading across the ridge was 60 km/m.y. (6 cm/year), a typical rate of seafloor spreading.
Why are the magnetic strips in the pacific ocean wider than the ones in the Atlantic ocean?
The Pacific seafloor formed at a faster spreading rate than the Atlantic seafloor.
In which part of the earth does the temperature at the greatest rate with depth?
well it is either the crust, the stiffer mantle, the outer core, or the inner core.
What affects the age of the ocean floor?
The distance and rate at which they are growing from "mid-ocean ridges" from which molten rock (magma) rises from the Earth's mantle. Younger rock is closest to these ridges while older rock is further. The old rock will eventually be recycled into the mantle via a process known as "subduction", marked by trenches in the ocean floor. - source: Essentials of Geology 3rd Edition (Marshak, 42)
The rate of seafloor spreading can be calculated by?
b. Knowing the various dates for the magnetic pole revesals, and the distance from the location of a known reversal site to the ocean ridge.
Which would have the fastest pulse rate adult adolescent child or infant?
Infants will have the fastest pulse rate.
The average spreading rate for fast spreading divergent plates?
100-200 mm
Is the North Atlantic spreading faster than the South Atlantic?
Neither is spreading faster. They are both spreading at the same rate.
Does geomagnetic reversals represent a source of information on the rate of sea-floor spreading?
As mid ocean ridges create new seafloor over extended periods of time, the magnetic poles of the Earth reverse back and forth. The rocks on either side of a mid ocean ridge show the opposite magnetisms and appear striped. From knowing the approximate ages of these magnetic reversals, one can estimate the approximate age of each stripe.
