Question

3.

Answer 1

When scientists plotted the points of normal and reversed polarity on a seafloor map the type of pattern that did they discover in the magnetic polarity is option A: stripes of normal and reversed polarity.

What do you mean by Reversed Polarity?

The presence of reverse magnetic polarity found in the opposite sides that is south and northern parts of the ridges is due to the magnetic properties of the magma which get aligned to the earth's magnetic fields.  

Magnetism on the seafloor leads to ridges having reversed and normal polarity. These ridges often alternate. The reverse polarities and old and new sea floors are found in association to the spreading of magma in the opposite direction of the ridges.

The first ridge to the right will have a normal polarity. The next ridge will be reversed and this trend will then repeat till the end.

Therefore, correct option is A.
