Answer 1

The correct statement that describes the creation and destruction of ocean rock as they undergo seafloor spreading is:

New rock is created at mid-ocean ridges and is then reabsorbed in ocean trenches.

This process occurs as magma rises at mid-ocean ridges to form new oceanic crust, and older crust is eventually subducted back into the mantle at ocean trenches.
