Answer

Brief Explanations:

Seafloor - spreading theory suggests new oceanic crust is formed at mid - ocean ridges. Younger rocks being closer to mid - ocean ridges indicates new crust formation there, supporting the theory. The destruction of crust at trenches is related to subduction, not the original evidence for seafloor spreading. Pillow - shaped rocks and magnetic stripes are later confirmations.

Answer:

Younger rocks are closer to mid - ocean ridges.
