SOLAR SYSTEM

Detailed explanation-1: -At the mid-ocean ridge spreading axis, these flips in the direction of the Earth’s magnetic field are recorded in the magnetization of the lava. This creates a symmetrical pattern of magnetic stripes of opposite polarity on either side of mid-ocean ridges.

Detailed explanation-2: -Paleomagnetism-Many rocks record the strength and direction of the earth’s magnetic field at the time the rocks formed.

Detailed explanation-3: -When the Earth’s magnetic field reverses, a new stripe, with the new polarity, begins. Such magnetic patterns led to recognition of the occurrence of sea-floor spreading, and they remain some of the strongest evidence for the theory of plate tectonics.

Detailed explanation-4: -These changes in strength and direction of the Earth’s magnetic field are recorded in the volcanic rocks beneath the seafloor.
