Yes, some research suggests that bats may use the Earth's magnetic fields for navigation during their nightly flights. However, the exact mechanisms and extent of this ability are still being studied and are not fully understood.
The Earth's magnetic field is generated by the movement of molten iron in the outer core, driven by heat from radioactive decay and the cooling of the planet. This movement creates electric currents, which in turn produce a magnetic field around the Earth.
There is no scientific evidence to suggest that the polarity of Earth's magnetic field will change in 2012 or any time soon. The Earth's magnetic field has undergone numerous reversals throughout its history, but these events occur over thousands of years, not within a single year.
The Earth's magnetic field is strongest at the North and South magnetic poles, which are not the same as the geographic North and South poles. The magnetic field strength varies at different locations on the Earth's surface.
Yes, a compass works by aligning itself with the Earth's magnetic field to determine direction. The needle in a compass is magnetized and will point towards the Earth's magnetic north pole.
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.
Ancient pottery shows movement of the earth's magnetic field. Firing the pottery fixes the ambient magnetic field in the fired pottery.
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.
magnetic rocks on the ocean floor show that the Earths magnetic field has been frequently reversed forming new sea floor.
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 molten iron and medals inside the earths core are the reasons for the earths magnetic core.
the heliocentric system and the geocentric system
Yes.
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.
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.
Because the earths magnetic poles move around from year to year, and even day to day.
because it has the hydro electric power to control the earths magnetic field
