Magnetic Stripping is Evidence of?
pole reversals
The needle of a magnetic compass points toward the?
North. It can, what they call "dance" if you are near magnetic rock though.
How do judicial reviews in the majority opinion differ from those in the dissent?
The majority opinion uses lower courts' decisions on the same case as evidence
The evidence collector is not concerned with?
Determining the natural variations that exist in physical evidence
Is hear say evidence enough to be indicted?
A hear say evidence is not enough for a person to be indicted.
What is magnetic striping evidence?
Magnetic reversals and sea floor spreading.
What Magnetic striping evidence of?
Magnetic reversals and sea floor spreading.
What is magnetic striping evidence of?
Magnetic reversals and sea floor spreading.
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.
Magnetic striping of evidence of?
Magnetic reversals and sea floor spreading.
What causes the magnetic striping noticed about the mid ocean ridges?
These "stripes" formed the pattern known as magnetic striping. ... They hypothesized that the magnetic striping was produced from the generation of magma at mid-ocean ridges during alternating periods of normal and reversed magnetism by the magnetic reversals of the Earth's magnetic field.
What concepts did magnetic striping reveal to scientists about the rock on either side of a spreading ridge?
Magnetic striping revealed that the rock on either side of a spreading ridge is symmetrical and parallel. This indicated seafloor spreading and demonstrated that new oceanic crust is formed at mid-ocean ridges as magma solidifies and creates a record of Earth's changing magnetic field over time.
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.
What struture on the seafloor would have magnetic striping?
The Mid Ocean Ridge would have magnetic striping. As the seafloor expands, new oceanic crust is spread in either direction. As this process continues over many years, the magnetic poles may switch, altering the magnetism in the new crust. The poles will switch back and forth, producing the magnetic striping that is easily discernible when examining the Mid Ocean Ridge and surrounding seafloor.
How was magnetic striping used to explain age of the seafloor?
it was use by watching porn
What Causes of magnetic striping?
Magnetic striping on the ocean floor is caused by the movement of tectonic plates. As new oceanic crust is formed at mid-ocean ridges, Earth's magnetic field causes iron-rich minerals in the crust to align and record the direction of the magnetic field at that time. This results in alternating patterns of magnetic polarity stripes on the ocean floor.
Used as evidence for sea-floor spreading?
Magnetic striping on the ocean floor is used as evidence for seafloor spreading. As new oceanic crust forms at mid-ocean ridges, Earth's magnetic field is recorded in the rocks in alternating patterns of normal and reversed polarity. This provides support for the idea that new crust is continuously being created at mid-ocean ridges and spreading away in opposite directions.
