Magma acquires the magnetic direction present on Earth when it hardens into rock

Answer 1

The two correct answers that identify the factors 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 two factors explain how the Earth's magnetic field is recorded in newly formed rock at mid-ocean ridges and how the movement of tectonic plates contributes to the formation of magnetic stripes.
