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