Magnetism in rocks can reveal several pieces of information. Here are the points that are associated with the question:
1. Mass: Magnetism itself does not directly reveal the mass of a rock. To determine the mass, you would typically need to use a balance or scale to measure the weight of the rock.
2. Luster: Magnetism plays no role in determining the luster of a rock. Luster refers to the way light interacts with the surface of a mineral or rock, and it is usually determined by visual observation.
3. Age: Magnetism can be used to determine the age of certain rocks through a method called paleomagnetism. When rocks form, minerals within them can align themselves with the Earth's magnetic field. By studying the magnetic alignment in rocks, scientists can infer information about the past magnetic field of the Earth and the approximate age of the rocks.
4. Minerals: Magnetism can help identify certain minerals within rocks. Some minerals are magnetically sensitive and can be attracted or repelled by a magnet. By observing the behavior of a rock in the presence of a magnet, it is possible to identify if it contains magnetic minerals.
In summary, while magnetism does not directly reveal the mass or luster of rocks, it can provide valuable information about their age and the presence of certain minerals. To obtain more specific information about each factor, additional testing or analysis would generally be required.
