3rd angle=2(36)=72
4th angle =36
If you look on openstudy.com they have lots of answers to this :-)
The ocean crust is known to show a sequence of magnetic polarity given that it shows us that there is the formation of a new sea floor at the mid ranges of the ocean. This is where they are seen to separate from themselves on the sides of the ridge.
<h3>What is seafloor spreading?</h3>
This is the term that is used to refer to the spreading that occurs at the mid ocean ridges. These are the areas where the new oceanic crusts get to be formed.
Hence we can say that The ocean crust is known to show a sequence of magnetic polarity given that it shows us that there is the formation of a new sea floor at the mid ranges of the ocean. This is where they are seen to separate from themselves on the sides of the ridge.
