Is there magnetic strips on the ocean floor are places where oceanic crust sink back to the mantle?
Is there magnetic stripe son the ocean floor are places where oceanic crust sink back to the mantle
Do magnetic stripes on the ocean floor oceanic crust sink back into the mantle?
No, the magnetic stripes on the ocean floor form due to the alignment of magnetic minerals in the crust as it solidifies from the mantle. The oceanic crust is eventually consumed in subduction zones and recycled back into the mantle, but the magnetic stripes themselves do not sink back into the mantle.
What is the name of the process that causes mantle movement?
The process that causes mantle movement is called mantle convection. This occurs when heat from the Earth's core causes the mantle material to heat up and rise towards the surface, then cool and sink back down in a continuous cycle.
What process in which new sea floor forms as older sea floor is pulled apart?
Seafloor spreading where new floor is formed. Subduction zone where older floor is pushed back into the mantle.
Is magnetic stripes on the ocean floor the places where oceanic crust sinks back to the mantle?
it is right in your book soo... you should be able to answer this
What is a result in the process where the ocean floor sinks beneath the crust and back into the mantle?
The process where the ocean floor sinks beneath the crust and back into the mantle is known as subduction. This is the result of the collision of two tectonic plates. This in turn results in the formation of fold mountains and volcanism (such as that which occurs in the Western US - for example Mt. St. Helens and the Western coast of South America).
What process is shown occurring at C and what does it occur?
In a process taking tens of millions of years, part of the ocean floor sinks back into the mantle at deep ocean trenches.
Why is the earth 4.6 billion years old but the oldest sea floor is only 180 millions years old?
Just as new sea floor forms at mid-ocean ridges, new sea floor is forced back into the mantle at abduction zones. The oldest seafloor is at east and west the edges of the Atlantic Ocean, dating to the breakup of Pangaea.
True or false magnetic stripes on the ocean floor are places where oceanic crust sinks back to the mantle?
True. Magnetic stripes on the ocean floor are created by alternating bands of magnetic polarities in the oceanic crust. These stripes are evidence of seafloor spreading where new crust is formed at mid-ocean ridges, pushing older crust away. Subduction zones are where older crust sinks back into the mantle.
What does a plate tectonic look like?
its just like a cracked hard boiled egg the shell are the plates and the egg while is the mantle. the tectonic plates move on top of magma which is the mantle. they move due to convection currents which occur within the mantle the oceanic plates sub duct in to the mantle while the continental plates don't as they are not as dense. they basicly freeze and move sideways and then descend back in to the mantle again just very slowly. just like a massive jigsaw puzzle. if you get a hard boiled egg and crack it and wiggle it around it might become clear!!!
What creates the currents in the mantle of the earth?
The heat generated from the decay of radioactive elements in the Earth's interior drives convective currents in the mantle. This process causes the hot mantle material to rise towards the surface, cool, and then sink back down in a circular motion known as mantle convection.
What is the process of the ocean floor sinking beneath a deep ocean trench and back into the mantle known as?
The process of the ocean floor sinking beneath a deep ocean trench and back into the mantle is known as subduction. This occurs at convergent plate boundaries where one tectonic plate is forced beneath another due to differences in density. Subduction zones are associated with volcanic activity and the formation of mountain ranges.
