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

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

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

Answer 1

The two correct answers that cause magnetic stripes to form along the ocean floor are:

1. Rock forming at the oceanic ridge pushes older rock outward in both directions.
2. Magma acquires the magnetic direction present on Earth when it hardens into rock.

These processes contribute to the formation of magnetic stripes as new magma rises at mid-ocean ridges and solidifies, capturing the Earth's magnetic field direction at that time. As tectonic plates move apart, older rocks are displaced outward, creating the symmetric pattern of magnetic stripes on either side of the ridge.
