Magnetic orientation of rock refers to the alignment of magnetic minerals within the rock with the Earth's magnetic field at the time of formation. This alignment can provide information about the past magnetic field of the Earth and help in determining the rock's age and geological history.
What else can I help you with?
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 -_-
The magnetic record in the rock on the ocean floor depends on when the rock was?
The magnetic record in the rock on the ocean floor depends on when the rock was formed. When molten rock solidifies, it locks in the orientation of the Earth's magnetic field at that time. This provides a record of past magnetic field reversals and helps in studying the movement of tectonic plates.
What do bands of rock on the seafloor showing alternating magnetic orientation indicate about the earths magnetic field?
Bands of rock on the seafloor showing alternating magnetic orientation indicate times when the Earth's magnetic field has reversed. These bands are created as new oceanic crust forms at mid-ocean ridges and records the direction of the Earth's magnetic field at the time of its formation. Studying these bands provides insight into the history of Earth's magnetic field reversals.
What happens to the magnetic orientation of rocks as the poles reverse?
During a magnetic pole reversal, the magnetic orientation of rocks changes to align with the new orientation of the Earth's magnetic field. This means that the magnetization of rocks will also reverse during a geomagnetic field reversal event.
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 orientation of a rock’s magnetic field can tell you its?
The orientation of a rock's magnetic field can tell you the direction in which the rock was formed, as the magnetic minerals in the rock align themselves with the Earth's magnetic field at the time of formation. It can provide insights into the geological history of the rock, including its age and past movements.
The magnetic orientation of a rock is determined when the rock solidfies?
True
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
True or False the magnetic orientation of a rock is determined when the rock solidifies?
True. The magnetic orientation of a rock is locked in when the rock solidifies and cools below a certain temperature known as the Curie point. This is due to the alignment of magnetic minerals in the rock with the Earth's magnetic field at the time of solidification.
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
What does the magnetic dip preserved in a rock indicate?
The magnetic dip preserved in a rock indicates the orientation of the Earth's magnetic field at the time the rock was formed. This information can be used to determine the past position of the rock relative to the magnetic poles and can provide insights into the Earth's changing magnetic field over time.
Bands of rock the seafloor showing alternating magnetic orientation indicate earth's magnetic field has?
reversed itself in the past. hth :)
What can the orientation of a rocks magnetic field can tell you?
The orientation of a rock's magnetic field can provide information about the rock's formation and past geological processes. It can indicate the rock's original position when it formed, whether it has been subjected to tectonic movements or heating events, and reveal the Earth's magnetic field at the time of the rock's formation.
What happenes to the magnetic orientation of rock as the poles reverse?
There is nothing -_-
Why does volcanic rock magnetize?
Volcanic rock, especially basalt, contains some iron. When the rock is still molten the particles of iron are free to move, but are influenced by Earth's magnetic field. When the lava hardens into rock these iron particles are locked in place, essentially recording the orientation of Earth's magnetic field.
