Volcanic rock shows that some layers have magnetic fields that are aligned opposite to Earths This evidence BEST fits which hypothesis?

The evidence of volcanic rock layers with opposite magnetic fields to Earth's aligns with the hypothesis of geomagnetic reversal. This suggests that Earth's magnetic field has flipped polarity multiple times throughout its history.


What evidence is there that the earths magnetic fields move?

Ancient pottery shows movement of the earth's magnetic field. Firing the pottery fixes the ambient magnetic field in the fired pottery.


What are Other than earth is also known to have magnetic pole reversals?

Other than Earth, Mars is also known to have experienced magnetic pole reversals in its history. Evidence from the planet's crust suggests that its magnetic field has reversed multiple times over millions of years, similar to Earth's magnetic field reversals.


Why are magnet patterns important evidence for plate tectonics?

magnetic rocks on the ocean floor show that the Earths magnetic field has been frequently reversed forming new sea floor.


What changes in cosmic ray intensity at earths surface would you expect during periods in which earths magnetic field passed through a zero phase while undergoing pole reversals?

Cosmic ray intensity at Earth's surface would be greater when Earth's magnetic field passed through a zero phase because magnetic shifting is minimal. Fossil evidence suggests that the periods of no protective magnetic field may have been as important in changing life forms as x-rays have been in the famous heredity studies of fruit flies.


The possible source of earths magnetic core is?

The molten iron and medals inside the earths core are the reasons for the earths magnetic core.


What evidence is there for the earths revolution around the sun?

the heliocentric system and the geocentric system


Is earths core a source of earths magnetic field?

Yes.


Earth's magnetic field results from the spinning of the?

The earths magnetic field results from deep in the earths core. Magnetic conduction from within the earths core is believed to be the cause of this.


What on the ocean floor is evidence that earths magnetic field changes?

Evidence that Earth's magnetic field changes can be found in the alignment of magnetic minerals in rocks on the ocean floor. As magma solidifies into new rock, the magnetic minerals within it align with the current magnetic field direction. By studying the alignment of these minerals in rocks of different ages along the ocean floor, scientists can track changes in the Earth's magnetic field over time.


Why is it hard to read a compass when standing at one of the earths poles?

Because the earths magnetic poles move around from year to year, and even day to day.


Why do scientists believe that the inner core is the source of earths magnetic field?

because it has the hydro electric power to control the earths magnetic field
