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
Anywhere on Earth Anywhere on Earth Anywhere on Earth (AoE) is a calendar designation which indicates that a period expires when the date passes everywhere on Earth. The last place on Earth where any date exists is on Howland and Baker islands, in the time zone (the West side of the International Date Line), and so is the last spot on the globe for any day to exist. Therefore, the day ends AoE when it ends on Howland Island. The convention originated in IEEE 802.16 balloting procedures. At this point, many IEEE 802 ballot deadlines are established as the end of day using
