Flangea

Flangea is a term that appears in speculative and fictional contexts to describe a hypothetical supercontinent. It is not a term used in formal geological nomenclature, and there is no generally accepted scientific model or timeline associated with it. In discussions outside peer‑reviewed geology, Flangea is typically introduced as a convenient fictional reference point to illustrate how large landmasses might assemble or reassemble through plate tectonics.

In its speculative use, Flangea is imagined as a single, extensive landmass formed by the convergence of major continental blocks. Descriptions vary, but such a configuration is usually presented as a rough, sprawling continent with interior seas, diverse climates, and varied biomes depending on the assumed latitude and interior geography. Because it is hypothetical, there is no standardized outline, size, or configuration for Flangea.

Historical and literary usage of the term tends to occur in worldbuilding, science fiction, or classroom exercises designed to teach concepts of plate tectonics, continental drift, and supercontinent cycles without implying that Flangea ever existed in Earth’s history. The more established historical landmasses discussed in geology include Pangaea, Gondwana, and Laurasia, while speculative future configurations are sometimes named separately (for example, Pangea Ultima or Amasia).
