How fast do plates move relative to each other?
The plates move relative to each other in varying speeds. The Pacific plate moves against the North American plate at 5 cm/yr. The Arctic Ridge has the slowest rate at less than 2.5 cm/yr., while the East Pacific Rise has the fastest rate at more than 15 cm/yr.
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.
What is the modern seafloor spreading rate range?
Typical rates of spreading average around 5 centimeter (2 inches) per year.
What do scientists use to measure the rate of movement of oceanic plates?
sea-floor spreading
How do you calculate half sea floor spreading rate?
The distance in kilometers of anomaly known (distance) divided by age of anomaly.
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.

How fast is the movement of the crust in a year?
This depends at what point on Earth's surface you are interested in! For example the Mid Atlantic Ridge separating the North American and Eurasian plates is classified as a "slow" spreading centre with a spreading rate of around 25mm/yr (slow spreading centres generally have a rate of between 20-55 mm per year). This means that the North American plate is moving roughly to the west at a rate of 12.5 mm/yr. However a number of the spreading centres in the Pacific are considered to be "medium to fast" spreading centres with rates of between 80-120 mm/yr. Another example is the Indian plate which is moving north-east at a rate of approximately 50mm/yr causing it to collide with the more slowly moving Eurasian plate. This event started (and is continuing to cause) the Himalayan orogeny.

Which of the mid ocean ridges has the fastest spreading rate?
The Pacific region spreads 80-120 mm/yr, while the north Atlantic Ocean is just ~ 25 mm/yr.
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.
What cause the inflation rate to spike up sharply?
prices on world oil markets rise steely due to war in the middle east
Why are magnetic bands in the eastern pacific ocean so far apart compared to the magnetic bands along the mid Atlantic ridge?
If true, it would indicate that the divergent plates of the eastern Pacific are spreading at a faster rate than the plates of the Mid-Atlantic Ridge.

If true, it would indicate that the divergent plates of the eastern Pacific are spreading at a faster rate than the plates of the Mid-Atlantic Ridge.
What is interest rate rise?
An interest rate rise is when a person is late on a bill such as a credit card or insurance bill and the interest rate the person pays goes up.
What is the modern seafloor spreading rate range?
Typical rates of spreading average around 5 centimeter (2 inches) per year.
