The statement that accurately describes the aspects of plate tectonics that involve sub-duction and seafloor spreading is :
Crust is created at the coastlines of continents.
Both the continental landmasses and the ocean floor are part of the earth's crust. This crust is broken into individual pieces called tectonic plates.
1. Older crust is melted at subduction zones.
2. Oceanic crust is created at mid-ocean ridges.
4. Continents move due to seafloor spreading and subduction.
