The history of reversals can be observed on the ocean floor through magnetic striping. When new oceanic crust is formed at mid-ocean ridges, magnetic minerals align with the Earth's magnetic field. Over time, as the Earth's magnetic field reverses, these minerals record the reversals in alternating magnetic stripes on the ocean floor. This provides evidence for the history of reversals.
If Earth's magnetic field was fixed without reversals, newly-formed seafloor basalts would only show one magnetic orientation. This uniformity would make it harder to track the movement of tectonic plates or determine the age of the seafloor using magnetic stripes. It would also impact our understanding of plate tectonics and Earth's geology.
If Earth's magnetic field was fixed in place and did not reverse polarity, seafloor basalts would display a consistent magnetic orientation, making it more challenging to track long-term changes in Earth's magnetic field. This could impact our ability to study plate tectonics, as we rely on changes in magnetic polarity recorded in seafloor basalts to understand the movement of tectonic plates over time.
It indicates that the crust is growing equally over time on either side of a mid-ocean divergent plate boundary. The magnetic orientation indicates the direction of the magnetic pole at the time the rock's magnetic minerals solidified from lava or magma.
Uh, no. It would have to be metal. It is normally non-magnetic BUT it CAN be magnetic if combined with one or more metals.
The Mid Ocean Ridge would have magnetic striping. As the seafloor expands, new oceanic crust is spread in either direction. As this process continues over many years, the magnetic poles may switch, altering the magnetism in the new crust. The poles will switch back and forth, producing the magnetic striping that is easily discernible when examining the Mid Ocean Ridge and surrounding seafloor.

Devoid of life, as the magnetosphere is what prevents the solar winds from striping the planet of atmosphere and destroying all life by irradiation. Compasses would also cease working.

If I am referring to stripes then it would be striping. Example: I am striping this object with paint. Stripping with two p's refers to an act of removing one's clothes. Example: I am stripping off my work clothes to change into my pajamas.
Beryllium is not attracted to magnets because it is a non-magnetic element. Its magnetic properties are determined by its atomic structure, which lacks unpaired electrons that would create a magnetic field.
Scientists now know about plate tectonics, which explains how Earth's outer shell is divided into large plates that move and interact with each other. This understanding supports Wegener's theory of continental drift, as it provides a mechanism for the movement of continents over time. Additionally, evidence from ocean floor mapping, seafloor spreading, and magnetic striping further supports the concept of plate tectonics.

If you looked at a magnet through a microscope, you would see the arrangement of its magnetic domains and possibly the alignment of its magnetic fields. This would give you a closer look at the microscopic structure of the magnet and how its north and south poles are distributed.
