Question

oceanic crustal materials of different ages are arranged on earths surface in a pattern that can be attributed to ______.

○ impacts from ancient asteroids that collided with earth
○ weathering and erosion
○ tectonic plate activity
○ ocean currents

Explanation:

Oceanic crust forms at mid-ocean ridges (a type of tectonic plate boundary) and moves away over time, creating a pattern where crust age increases with distance from the ridges. Asteroid impacts, weathering/erosion, and ocean currents do not create this organized age pattern of oceanic crust.

Answer:

tectonic plate activity
