Identify the factors that cause magnetic stripes to form along the ocean floor. Select the two correct answers. 1 . Magnetic direction of rock changes as Earth s
magnetic poles drift.
2. Magma acquires the magnetic direction present on Earth when it hardens into rock
3. Plates move as new rock forms which causes magnetic direction to skew away from normal
4. Rock forming at the
oceanic ridge pushes older rock outward in both directions.

The factors causing magnetic stripes are ''magma acquires the magnetic direction present on Earth when it hardens into rock' and 'rock forming at the oceanic ridge pushes older rock outward in both directions'.

In ocean floors, magnetic stripes can be exposed in the upper part of the walls of the fracture zones.

The magnetic stripes are a type of symmetrical pattern on both sides of the mid-ocean ridges, which can be used to determine the periodicity of reversals of the magnetic field.

The magnetic stripes generate as the oceanic crust pulls apart when the magma rises to the surface at mid-ocean ridges and generates new bands of the ocean floor.

In conclusion, the factors that cause magnetic stripes are ''magma acquires the magnetic direction present on Earth when it hardens into rock' and 'rock forming at the oceanic ridge pushes older rock outward in both directions'.

Magnetic bands along the ocean are caused when magma acquires the magnetic direction present on earth when the rock hardens and when rock formation on the oceanic crest pushes older rocks outward in both directions, as shown in options 2 and 4.

We can arrive at this answer because:

Magnetic bands form along with the separation between oceanic crust and magma.This happens above the mid-ocean ridges, which allows renewal of the seabed, which expands and generates new bands.As the oceanic crust separates, magma rises towards the surface, spilling over mid-oceanic ridges.In this case, the magma acquires the magnetic direction present on Earth as it cools, hardens, and becomes a rock.

These rocks push older rocks up and down, making room for the creation of magnetic bands along the ocean floor.
