Answer 1

Answer:

The age of seafloor rock increases as the distance from the mid-ocean ridge increases.

Explanation:

Mid-ocean ridges are a physical feature that occurs at divergent plate boundaries when the plate boundary is located in the ocean. This physical feature occurs because of more than usual intense activity in the upper mantle, resulting in cracking the crust and splitting up a tectonic plate, making the two, now divided pieces, to move away from each other.

The gap that is opening up between the plates is constantly filled with magma. The magma quickly cools off, creates new rock, and the rock piles up. This process goes on for millions of years, so the rock that has been formed initially has been pushed far away from the mid-ocean ridge by the constant creation of new rock, so the rock at the mid-ocean ridge is the youngest, while the more the distance increases from the mid-ocean ridge, the older the rock.
