Answer 1

$\small{\green}\fcolorbox{blue}{cyan}{\bf{\underline{\red{\color{red}Answer}}}}$

Magnetic Striping is when the sea floor is spreading, and magma from the mantle is rising through the Earth's crust. That magma then turns into new crust, forming the "Oceanic Crust".

Answer 2

At spreading centres, this crust is separated into parallel bands of rock by successive waves of emergent magma. When Earth's geomagnetic field undergoes a reversal, the change in polarity is recorded in the magma, which contributes to the alternating pattern of magnetic striping on the seafloor.
