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.


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.


What was the first magnetic rock called?

The first magnetic rock discovered is known as lodestone, a naturally magnetized form of the mineral magnetite. Lodestone has been used since ancient times for navigation and has played a significant role in the study of magnetism. Its magnetic properties arise from the alignment of iron oxide minerals within the rock.


A rock that has magnetic properties is?

Lodestone is a rock that has magnetic properties.


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 does solidified magma come 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.

What is magnetic orientation of rock?

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.

Where is the magnetic rock located called magnesium?

mostly where i live; in texas ; because texas is so high in drout it makes the earth's magnetic feild harden :)
