Answer 1

The two correct answers that explain the formation of magnetic stripes along the ocean floor are:

1. Magma acquires the magnetic direction present on Earth when it hardens into rock.
   As magma rises to the surface and solidifies at mid-ocean ridges, it retains the Earth's magnetic direction at the time of solidification, creating magnetic stripes.

2. Rock forming at the oceanic ridge pushes older rock outward in both directions.
   The process of sea-floor spreading at mid-ocean ridges pushes newly formed rock away from the ridge, while older rock is pushed outward, contributing to the alternating patterns of magnetic stripes.

These processes are key in developing the patterns of magnetic stripes that are observed in the oceanic crust.
