What is a magnetic rock called?
A magnetic rock is called magnetite. It is a naturally occurring mineral that exhibits strong magnetic properties. Magnetite can be found in various rock formations and is used in various industries for its magnetic properties.
What is the name of a magnetic?
Magnetic rock is called Lodestone.
What is the name of a rock?
Magnetic rock is called Lodestone.
The composition of igneous rock mainly made up of magnesium and iron is called?
Basalt
What is the dark colored igneous rock with rich in iron and magnesium?
The dark-colored igneous rock rich in iron and magnesium is called basalt. Basalt is a fine-grained rock that is commonly found in volcanic areas and oceanic crust. It is characterized by its dark color due to the presence of minerals like pyroxene and olivine.
A natually magnetic rock was indentified 2500 years ago by Greeks what is it called?
Magnetite.
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.

Is magnesium an igneous rock?
No. Magnesium is not a rock; it is a metallic element. It is present in some of the minerals found in igneous rocks. It does not occur naturally in its elemental form.
What is a sedimentary rock composed of calcium magnesium carbonate?
A sedimentary rock composed of calcium magnesium carbonate is known as dolomite. It forms from the mineral dolomite, which is similar to limestone but contains magnesium in addition to calcium. Dolomite often forms in marine environments through the replacement of limestone by magnesium-rich fluids.
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 is another word for magnetic rock?
Another word for magnetic rock is lodestone.
