The statement that best describes the cyclic nature of seafloor spreading is: New oceanic crust is created.

Seafloor spreading is a process that occurs at mid-ocean ridges where tectonic plates pull apart, allowing magma to rise and solidify, creating new oceanic crust. This process is continuous and part of a cycle that leads to the gradual movement of tectonic plates, the recycling of crust, and the dynamic nature of the Earth's surface.
