  1. If we use Neuendorf’s definition of continent: “one of the Earth’s major land masses, including both dry land and continental shelves.”, then there are really just four continents in the world: America-Eurafrasia (the Americas and Afro-Eurasia connected by the submerged Bering Land Bridge), Antarctica, Australia (aka Australia-New Guinea), and Zealandia (95% submerged beneath the Pacific Ocean).

    Does anyone know how many microcontinents have been discovered by the geologists so far? How many islands are part of a microcontinent? Where can I find a source for an updated list of microcontinents and a database containing the geological classification of the world’s major islands? The only source I could find is an outdated UNEP website which contains some archived info about the world’s islands, but their data haven’t been updated for more than 10 years.

    1. Hi Andy,
      Thanks for sharing your thoughts, it´s always good to have you around. I have found Neuendorf’s definition pretty accurate to what we consider a continent today. However, as I could read about the topic, I would say that continents are separated by the major tectonic plates in most cases. This is a tricky one to answer really, there is no consensus in the field yet.
      About microcontinents, I could not find any ‘official’ list or classification made by any institute or authority. There is an open debate and each specialist have his/her perspective.
