They collide with atoms of oxygen and nitrogen in the ionosphere and colored light is emitted. These colored lights make up the Northern and Southern Lights, the Aurora Borealis and Australis.
This is known as magnetic reversal when earth's magnetic poles change places.

No, Earth's magnetic poles are not located exactly on its geographical poles. The magnetic poles are located slightly off-axis and can shift over time due to changes in the Earth's magnetic field.

No, it is not true. The magnetic poles may be influenced by Earth's rotation, but they are certainly not defined by it.
The strength of Earth's magnetic field is strongest at the magnetic poles, which are not necessarily aligned with the geographic poles. The magnetic field is weakest at the magnetic equator.
Only the magnetic poles wanderD.Earth's magnetic and geographic poles are generally not in the same place.Geographic poles are defined by Earth's rotation.
Because the charged particles in the solar wind streaming from the sun are attracted to the magnetic poles.
The opposite poles of two magnets are attracted to each other due to magnetic force because of the alignment of their magnetic fields. This alignment creates a force that pulls the opposite poles together, resulting in attraction.
Because the earths magnetic poles move around from year to year, and even day to day.
