Where is active seafloor spreading occurring today?
At any divergent plate margin: The Mid-Atlantic Ridge The boundary between the African Plate and Arabian Plate (the Red Sea) Great Rift Valley West Antarctic Rift East Pacific Rise Pacific-Antarctic Ridge Galapagos Rise Gakkel Ridge
What structure on the seafloor would have magnetic striping?
A mid-ocean ridge would have magnetic striping on the seafloor. This striping is caused by the alternating polarities of Earth's magnetic field recorded in the basaltic rocks as they cool and solidify at the mid-ocean ridge, providing evidence for seafloor spreading.
First related the symmetrical magnetic patterns in seafloor basalts to seafloor spreading at a mid-ocean ridge?
Lawrence W. Morley, Frederick John Vine, and Drummond Hoyle Matthews were the first to tie magnetic stripe anomalies to seafloor spreading. The magnetic anomalies was the first evidence that supported the theory of seafloor spreading.
Which evidence causes most scientists to believe that seafloor spreading occurs at the mid-atlantic ridge?
The presence of magnetic stripes on either side of the mid-Atlantic ridge supports the theory of seafloor spreading. These stripes align with Earth's magnetic field reversals recorded in rock formations, indicating that new crust is constantly being formed at the ridge, pushing older crust away. Additionally, age dating of seafloor rocks shows that crust near the ridge is much younger than crust farther away, confirming the process of seafloor spreading.
How does seafoor age and magnetic clues support seafloor spreading?
Seafloor is youngest near the mid-ocean ridges and gets progressively older as you move away from the ridge. Magnetic stripes on the seafloor provide evidence of seafloor spreading, as they show alternating patterns of normal and reversed magnetic polarity that match the Earth's magnetic reversals over time. This supports the theory of seafloor spreading as new oceanic crust is created at the mid-ocean ridge and spreads outward.
How does the age of seafloor sediments change with increasing distance from the ocean ridge?
Age of seafloor rock and sediment increases with distance from the oceanic ridges.
How does the age of seafloor sediments change the increasing distance from the ocean ridge?
age increases
Where do midocean ridges intersect the landmasses?
Midocean ridges are areas where continents broke apart. Midocean ridges are closest to the landmasses in younger oceans. One example where a midocean ridge intersected a landmass is the Arabian sea, which was formed by the pulling apart of the Arabian Peninsula and Africa.
Where is active seafloor spreading occurring today?
At any divergent plate margin: The Mid-Atlantic Ridge The boundary between the African Plate and Arabian Plate (the Red Sea) Great Rift Valley West Antarctic Rift East Pacific Rise Pacific-Antarctic Ridge Galapagos Rise Gakkel Ridge
Is the Mid-Oceanic Ridge in the middle of the Atlantic Ocean?
One of the midocean ridges is, but others are in other oceans, seas, and bays.
How does the age of seafloor sediments change the increasing distance from the oceans ridge?
age increases
Is ocean crust formed at a mid ocean ridge?
Yes, the process that creates oceanic crust on a mid-ocean ridge is called "seafloor spreading". seafloor spreading creates a new oceanic crust that forms on the mid-ocean ridge.
Who first related the symmetrical magnetic patterns in seafloor basalt to seafloor spreading at a mid ocean ridge?
Vine and Matthews
What is the place were the seafloor if forced down into the mantle?
mid ocean ridge
What is Place were the seafloor is force down into the mantle?
mid ocean ridge
What structure on the seafloor would have magnetic striping?
A mid-ocean ridge would have magnetic striping on the seafloor. This striping is caused by the alternating polarities of Earth's magnetic field recorded in the basaltic rocks as they cool and solidify at the mid-ocean ridge, providing evidence for seafloor spreading.
Is seafloor spreading in the rift valley or along outsides of ridge?
rift valley
