The two correct answers that identify the factors causing magnetic stripes to form along the ocean floor are:
- Magma acquires the magnetic direction present on Earth when it hardens into rock.
- Rock forming at the oceanic ridge pushes older rock outward in both directions.
These processes contribute to the creation of magnetic stripes, as new magma solidifies at mid-ocean ridges and records the Earth's magnetic field at the time of its formation, while the movement of tectonic plates causes older rock to be pushed away, creating a pattern of magnetic stripes symmetric to the ridge.
