Aurora Borealis or the Northern Lights occur when solar activity ejects a cloud of gas. When the cloud of gas hits Earth's magnetic field, it causes complex changes to the magnetic field, These changes generate currents of charged particles, which then flow along lines of magnetic force into the Polar Regions. These particles are boosted in energy in Earth's upper atmosphere, and when they collide with oxygen and nitrogen atoms, they produce dazzling auroral light.
In reality, the sun is white. It appears to be different colors because of the way sunlight reflects off the atmosphere. The sun never changes color.
First of all, we're pretty sure that you're referring to "variation", not "declaration".Magnetic variation is the difference between the direction from you to the north pole (called "true north"), and the direction in which your magnetic compass points.That difference changes with your position on earth, because the north pole and theplace your compass points to are two different places. If you were standing at the point that's exactly halfway between them, then your compass would point exactly away from the north pole. And if you're not between them, but you're standing on the extension of the line between them, then your compass it pointing at the north pole, because both points are in the same direction from you.If you look at a navigational map, you will see lines of magnetic variation printed on the map. If you read your magnetic compass and apply the magnetic variation (printed on the map), you can calculate the direction of TRUE north.
Cosmic radiation would increase substantially, probably wiping out many life forms.

Electromagnetic waves, like light, do involve changes in the electric and the magnetic field. These changes propagate at the speed of light - as a wave.Electromagnetic waves, like light, do involve changes in the electric and the magnetic field.

answer
From changes in its magnetic field, assuming that the magnetic field rotates with the core.
A magnetic field
Not typically. Barereceptors respond to touch and pressure. Atmospheric changes are too small to activate them.
The magnitude of the magnetic field is decreased
It changes over time through direction and strength. So therefore Magnetic North becomes Magnetic South.
Yes evry millinium it changes
Because of the trades
Uniform magnetic field depends on the position of its surrounding. A non uniform magnetic field changes its position from one place to another.
