Continent Europe and Asia together as a single continent, dubbed "Eurasia". In this model, the world is divided into six continents, with North America and South America considered separate continents. Geologists use the term "continent" in a different manner from geographers. In geology a continent is defined by continental crust: a platform of metamorphic and igneous rock, largely of granitic composition. Some geologists restrict the term 'continent' to portions of the crust built around stable Precambrian "shield", typically 1.5 to 3.8 billion years old, called a craton. The craton itself is an accretionary complex of ancient mobile belts (mountain belts) from
The Continent Makers land area of the overpopulated twenty-second century Earth by creating new continents through the manipulation of geological forces. The project's initial goal is to raise a new land mass to be called Gamanovia around the existing Ascension Island in the South Atlantic. The name of the proposed new continent was chosen to honor fifteenth century Portuguese navigator Vasco da Gama, the first European to navigate the region's waters, and for João da Nova, who discovered Ascension Island a few years later.
