Question 12 • 2026-27 AL-Earth and Space Science

How does oceanic crust move along mid-ocean ridges?

Answer
A
away from dense crust
B
parallel to the ridge
C
away from the ridge
D
under less dense crust

Explanation

At mid-ocean ridges, magma rises and cools to form new oceanic crust. As newer crust forms, it pushes the older crust outward on both sides of the ridge, so oceanic crust moves away from the ridge. The correct choice is “away from the ridge.”
