What minerals have magnetic properties?
The following minerals have magnetic properties: Magnetite and hematite are ferromagnets. Ferrites and garnets are ferrimagnetic. Quartz, calcite, and mica are all magnetic. Although they have a small magnetic attraction, these minerals do not remain magnetic.
How do magnetic bands provide evidence that tectonic plates are moving apart at mid-oceanic ridges?
Through seafloor-spreading as iron rich minerals cool they become magnetized in the direction parallel to the existing magnetic field. As the magnetic fields change direction so will the magnetized minerals, allowing scientists to record each change in the seafloor as it spreads.
What are nonferrous minerals?
non ferrous minerals are those minerals which do not contain an appreciable amount of iron. These generally do not show magnetic or conducting properties .
What properties of minerals are considered special properties that apply to only a few minerals?
Those would be properties like magnetism, fluorescence, triboluminescence.
Paleomagnetism is proven by evidence of changes in?
Evidence of paleomagnetism can be found in basalt that has cooled from lava. Other evidence is that any rock with magnetic minerals are presents, and sedimentary rocks where minerals form from ion bearing ground water.

How does magnetic reversals provide evidence for seafloor spreading?
Because of the stripes at the sea floor which are magnetic minerals

What mineral is in a rock that's magnetic?
Many minerals have magnetic properties. Lodestone, for instance, is composed mostly of the mineral magnetite.
How do scientists identify minerals?
Scientist identify minerals by Their Special properties. An example of a special propertie is a Chemical Reaction .
What is sea floor spreading and what evidence do we have to prove it is happening?
Magnetic minerals on the ocean floor.

What properties of iron bearing minerals on the seafloor support the theory of seafloor spreading?
iron bearing minerals can record Earth's magnetic field direction. when Earth's magnetic field reverses, newly formed iron bearing minerals will record the magnetic reversal. magnetic reversals show new rock being formed at mid-ocean ridges. This helped explain how the crust could move
What rocks are magnetic?
Many rocks have magnetic properties (are capable of being magnetized, are magnetic or are attracted by a magnet) derived from magnetic minerals in their composition like magnetite, hematite, and ilmenite. The most well known magnetic rock is the lodestone, which is comprised mainly of magnetite.
