Magnetic stripes on opposite sides of the mid ocean ridge....

• Are much older than any other crust on the earth

• Are older on one side of the ridge and younger on the opposite side

• Are caused by the sun's constant radiation

• Are mirror images of each other. Each stripe on one side has an exact match on the other,
