With increasing distance from a mid-ocean ridge, the age of oceanic crust _____.
The age of oceanic crust increases with increasing distance from a mid-ocean ridge, where new crust is formed and spreads outwards. The option (B) is correct.
With increasing distance from a mid-ocean ridge, the age of the oceanic crust increases. This is because new crust is formed at the mid-ocean ridges, and as it spreads outwards, it pushes older crust away from the ridge.
This process is symmetrical on either side of the ridge, with crust aging approximately 1 million years for every 20-40 km away from the ridge. The oldest oceanic crust is found to be up to 280 million years old in the eastern Mediterranean and around 180 million years in the open ocean of the North Atlantic.
This question is not complete, Here I am attaching the complete question:

A) Decreases
