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

Plates move as new rock forms, which causes magnetic direction to skew away from normal.

Magnetic direction of rock changes as Earth’s magnetic poles drift.

Rock forming at the oceanic ridge pushes older rock outward in both directions.

Answer 1

The two correct answers that identify the factors causing 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 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.
