Look at the following picture of oceanic crust around a Mid-ocean ridge.
1. From this diagram, what observation can you make about the crust farthest from the Ridge (which is in Yellow/with dotted lines)
2. What process does this prove is happening around a mid-ocean ridge?
a
The further from the ridge, the more the crust is getting uplifted; this proves that this is a transform boundary.
b
The further from the ridge, the younger the crust is getting: this proves that subduction is occurring.
c
The further from the ridge, the more the rocks point North; this proves that Geomagnetism has been slowing shifting throughout Earth's existence.
d
The further from the ridge, the older the crust is: this proves that sea floor spreading is occurring and new oceanic crust is being made constantly.
1 answer
The correct answer to your question is:
d: The further from the ridge, the older the crust is: this proves that sea floor spreading is occurring and new oceanic crust is being made constantly.
This observation aligns with the process of sea-floor spreading, where new oceanic crust is formed at mid-ocean ridges and moves away from the ridge, becoming older as it gets farther from the source of formation.
