the length and severity of seasons the formation of new tectonic plates the direction of rotation of Earth on the axis the alignment of minerals in newly formed crust
I gave my students this multiple choice question: Evidence indicates that the magnetic field of Earth has reversed direction many times throughout history. After a magnetic reversal, which would most likely be affected?

Only one answer is correct among these 4 choices:
- the length and severity of seasons
- the formation of new tectonic plates
- the direction of rotation of Earth on the axis
- the alignment of minerals in newly formed crust

Could you tell me which one is correct?

the alignment of minerals in newly formed crust
