The two correct answers that cause magnetic stripes to form along the ocean floor are:
1. **Magma acquires the magnetic direction present on Earth when it hardens into rock.**
2. **Rock forming at the oceanic ridge pushes older rock outward in both directions.**
These processes are fundamental to the formation of magnetic stripes, as the cooling magma records Earth's magnetic field at the time of solidification, and the movement of tectonic plates leads to the creation of symmetrical patterns of magnetic stripes on either side of the mid-ocean ridges.
