How do magnetic stripes show the history of earths magnetic field

in geophysics in magnetic strip is a variation in the earth's magnetic field resulting in the variations in the chemistry and magnetism in rocks.

Explanation:

As you move away from an ocean ridge, the rocks get older

because the two particles have an equal charge, the charges will cancel out and give the atom an overall charge of 0. so, if at atom has 35 protons in the nucleus, we could expect it to have 35 electrons orbiting that nucleus.
