Magnetic strips on the seafloor are caused in part by?
Magnetic strips on the seafloor are caused in part by seafloor spreading, where new oceanic crust is formed at mid-ocean ridges. As the crust cools and solidifies, it locks in the polarity of the Earth's magnetic field at the time, creating a recorded history of magnetic reversals. This process creates alternating stripes of normal and reversed polarity as the seafloor expands.
What is being modeled at slits a and b as you pull the strips down through the base seafloor spreading?
As you pull the strips down through the base, slits a and b represent the divergent boundaries of tectonic plates at mid-ocean ridges, where seafloor spreading occurs. Magma rises from the mantle to fill the gap created by the separating plates, solidifying to form new oceanic crust. This process illustrates how tectonic activity leads to the continuous renewal of the ocean floor and contributes to the expansion of ocean basins over geological time.
What do strips of low intensity magnetism represent on the ocean floor?
it represents the fact that the magnetic poles of the Earth must "flip" from time to time - the iron in the magma that cools to become the ocean floor aligns with the poles so stripping would show that the poles have changed direction over time. Some scientists suggest the times when the poles "flip" match up with cataclysmic events in the Earths geologic history.
What do strips of alternating magnetic polarities found in rocks in the ocean basins provide?
Strips of alternating magnetic polarities found in ocean basin rocks provide evidence for seafloor spreading and plate tectonics. These magnetic anomalies are formed as magma cools and solidifies at mid-ocean ridges, recording the Earth's magnetic field at that time. The symmetrical pattern of these stripes on either side of the ridge indicates that new oceanic crust is created and pushes older crust away, supporting the theory of continental drift. This contributes to our understanding of the dynamic nature of the Earth's lithosphere.
How do strips of magnetized rock on the ocean floor provide evidence of sea-floor spreading?
Strips of ocean-floor basalt record the polarity of earth's magnetic field at the time the rock formed. These strips form a pattern that is the same on both sides of the mid-ocean ridge. the pattern shows that ocean floor forms along mid-ocean ridges and then moves away from the ridge.
Linear magnetic patterns associated with mid-oceanic ridges are configured as what?
Linear, magnetic patterns associated with mid-ocean ridges are configured as normal and reversed magnetized strips roughly parallel to the ridge. A very long lived magma source located deep in the mantle is called a hot spot.
Long raised strips of land called ridges run parallel to the coast?
These ridges are typically formed by the deposition of sediment by longshore drift or wave action. They can provide protection to the coastline by acting as a barrier against storm surges and erosion. Vegetation such as dune grasses often grows on these ridges, helping to stabilize them.

Earth's what field are recorded by rocks in strips parallel to ridges?
Magnetic fields are recorded by rocks in strips parallel to ridges on Earth's surface. This phenomenon is known as magnetic striping, and it provides evidence of seafloor spreading and the movement of tectonic plates over time.
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
What are strips of magnetic polarities found in rocks in ocean basins?
Strips of magnetic polarities found in rocks in ocean basins are known as magnetic anomalies. These anomalies occur due to the periodic reversal of Earth's magnetic field, which causes the newly formed oceanic crust at mid-ocean ridges to record the direction and intensity of the magnetic field at the time of solidification. As tectonic plates move apart, these alternating strips of normal and reversed magnetic polarity create a symmetrical pattern on either side of the ridge, providing evidence for seafloor spreading and plate tectonics.
What are strips of bacon called?
A rasher of bacon is a serving of bacon. This is generally several strips.
Strips of alternating magnetic polarities found in rocks in the ocean basins .?

What do the strips of rocks with their magnetic poles pointing in the opposite direction to Earth and magnetic poles represent on the ocean floor?
The strips of rocks with their magnetic poles pointing in the opposite direction to Earth's magnetic poles represent the phenomenon of magnetic reversal, which occurs when Earth's magnetic field changes direction. These alternating stripes are found on the ocean floor, particularly at mid-ocean ridges, and are evidence of seafloor spreading. As magma rises and cools at these ridges, it records the Earth's magnetic field at that time, creating a pattern of magnetic anomalies that reflects the history of geomagnetic reversals. This pattern helps scientists understand the age of the oceanic crust and the processes of plate tectonics.
Strips of wood which form a barrel?
Those strips, formed to make a barrel are called 'staves' .
Where the Strips of alternating polarities found in rocks in the ocean basis?
Strips of alternating polarities found in rocks in the ocean basins are the result of seafloor spreading. When new oceanic crust is formed at mid-ocean ridges, iron minerals in the magma align with Earth's magnetic field. Over time, as the crust moves away from the ridge, these magnetic minerals preserve the direction of the Earth's magnetic field at that time, creating alternating stripes of normal and reversed polarity on the seafloor.
