A Rift zone Underwater volcano?
Yes, also known as seafloor spreading! A rift zone volcano is called a mid-ocean ridge. The seafloor splits & spreads apart at a mid-ocean ridge, with lava seeping out of this fissure. The lava forms new seafloor. The older seafloor moves away from the ridge. Therefore, our ocean floor is actually spreading, at a rate of about two inches per year in the Atlantic ocean, and about 13 in the Pacific.
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.
What other evidence was needed to determine the rate of seafloor spreading?
The age of each strip of rock(K12 Science 6th Grade :p )
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.
Why are the 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.
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.
A Rift zone Underwater volcano?
Yes, also known as seafloor spreading! A rift zone volcano is called a mid-ocean ridge. The seafloor splits & spreads apart at a mid-ocean ridge, with lava seeping out of this fissure. The lava forms new seafloor. The older seafloor moves away from the ridge. Therefore, our ocean floor is actually spreading, at a rate of about two inches per year in the Atlantic ocean, and about 13 in the Pacific.
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.
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.
Are the North American Plate and the Eurasian Plate moving apart at a very slow rate?
Yes. The seafloor is spreading out from the Mid-Atlantic Ridge. The North American Plate is moving slowly SW from the boundary.
What occurs at divergent boundaries and creates new seafloor?
At divergent plate boundaries the spreading of the tectonic plates results in the reduced pressure of the underlying magma. As the spreading continues, lava fills in the area of spreading and cools, becoming the newest addition to the seafloor. This process occurs at a steady rate ranging from a few centimeters to several centimeters of new sea floor each year. However, at a different location opposite the newly formed seafloor are convergent plate boundaries where land and seafloor is destroyed to make room for new seafloor.
What is the modern seafloor spreading rate range?
Typical rates of spreading average around 5 centimeter (2 inches) per year.
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.
What is Mid-atlantic ridge spreading rate?
+- 2 cm per year
What wa needed to determine the rate of the seafloor spreading?
The age of each strip of rock(K12 Science 6th Grade :p )
What other evidence was needed to determine the rate of seafloor spreading?
The age of each strip of rock(K12 Science 6th Grade :p )
Which slavic country has the slowest rate of urbanization?
Moldova has the slowest rate of urbanization.
