Look at the following picture of oceanic crust around a Mid-ocean ridge.

Question

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 more the rocks point North; this proves that Geomagnetism has been slowing shifting throughout Earth's existence.
c
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.
d
The further from the ridge, the younger the crust is getting: this proves that subduction is occurring.

Answer 1

Based on your description of the oceanic crust around a mid-ocean ridge, the correct observation and inference would be:

1. The crust farthest from the ridge is older compared to the crust closer to the ridge.

2. This observation supports the following process:

c. 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 option accurately describes the phenomenon observed at mid-ocean ridges, where new crust is formed as tectonic plates pull apart, causing the crust closest to the ridge to be younger than that further away.
