The root element is the one created with the tag name "html". It contains the "head" and "body" sections, which in turn contain all other page elements.

How do you know what size it is to reference it to the size of text your looking to create? Is it automatically assigned to 16px?

The default size is determined by the browser, but 16px is standard in common ones.
