How does the age of sea floor sediments change with increasing distance from the ocean ridge? a) their age stays the same b)their age decreases c) their age varies without a pattern d)their age increases

D) their age increases

Option (D)

Explanation:

In a divergent plate motion, the plates move away from one another. As a result of this, the magma comes out to the ocean floor along the mid-oceanic ridge. The new materials are added to the crust along this mid-oceanic ridge. The rocks that are present near the mid-oceanic ridge are the younger rocks as the magma after ejection cools and solidifies. With the continuous eruptions, these rocks get shifted away from this ridge. So with the increasing distance from the mid-oceanic ridge, the age of the seafloor sediments increases.

Hence, the correct answer is option (D).
