Answer:
the magnetic direction of rocks along the surface of Earth and the age of rocks along the surface of Earth
Explanation:
The earth's magnetic field or geomagnetic field is believed to originate from the movement of molten iron and nickel in the outer core.
During a period in which the earth magnetic field is normal, crystallising magnetic minerals in magma records the orientation of the prevailing geomagnetic field. At other times when the field reverses and the magnetic field orientation changes, magnetic minerals in cooling magma stores this record.
To create a geomagnetic time scale, geologists can assign absolute ages to the records of these paleomagnetic anomalies which are the reversals. The rock is dated using radiometric techniques and each period of reversal is ascribed an absolute geologic age. Therefore, the magnetic direction of rocks along the surface of Earth and the age of rocks along the surface of Earth helps to build the geomagnetic time scale of the earth.
Answer:
To increase the preservation of an element, it should go through all the stages as it should, which could promptly take it to its ruin phase.
This must be analyzed from the theoretical point of view, it will be worthwhile for the human to go so fast through the phases of his life, shortening the chances of subsistence or we must burn all stages in due time.
It is an atom with a charge of 0 because a positive atom would be +1 charge and a negative atom would be -1 charge. So neutral would just be 0
