This section focuses on the process that generates the continental crust. I will argue that throughout most of geological history, the rocks of the continental crust were generated in subduction zones by processes very much like those that operate today. I will develop the idea in detail at the end of the section, but before doing this I consider some alternative models and explore the reasons why many authors reject subduction-related processes, at least during the earliest Archean crust.
