How is the orientation of Earth's magnetism recorded in rocks on the ocean floor?
Earths magnetic orientation is locked into the rock when the rock cools
What happenes to the magnetic orientation of rock as the poles reverse?
There is nothing -_-
What do bands of rock on the seafloor showing alternating magnetic orientation indicate about the earths magnetic field?
They indicate that the Earth's magnetic field has undergone shifting of the positions of it's poles several times in the past.
What causes Magnetic stripes on the seafloor are caused by?
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.
How can the magnetic orientation of rocks be used to trace a continent that has drifted?
When rocks are formed, usually from lava flows, the magnetic orientation of them is set as they solidify. As these rocks are affected by continental drift and other factors such as earthquakes, the original magnetic orientation remains. Using the known strengths of the earth's magnetic field over time, it is possible to then tell where these rocks originally emerged.
How is the orientation of Earth's magnetism recorded in rocks on the ocean floor?
Earths magnetic orientation is locked into the rock when the rock cools
The magnetic orientation of a rock is determined when the rock solidfies?
True
The orientation of a rock’s magnetic field can tell you its?
The orientation of a rocks magnetic field can tell you it's relative age.
How is the orientation of earths magnetism recorded in rocks on the?
Earth's magnetic orientation is locked into the rock when the rock cools
How is the orientation of earths magnetics recorded in the rocks on the ocean?
Earths magnetic orientation is locked into the rock when the rock cools
True or False the magnetic orientation of a rock is determined when the rock solidifies?
ture
What happenes to the magnetic orientation of rock as the poles reverse?
There is nothing -_-
Bands of rock the seafloor showing alternating magnetic orientation indicate earth's magnetic field has?
reversed itself in the past. hth :)
What is the outcome of Bermuda triangle?
The reason why compasses and GPS navigation's have lost their sense of orientation is because the ocean floor is made of magnetic rock which disturbs the compass' orientation.
How solidified magma comes to be magnetic?
As magma solidifies to form rock, iron-rich minerals in the magma align with Earth's magnetic field in the same way that a compass needle does. When the rock hardens, the magnetic orientation of the minerals becomes permanent. This residual magnetism of rock is called paleomagnetism.
