Since geography is defined by local convention, there are several conceptions as to which landmasses qualify as continents, and which might be termed supercontinents (e.g. Africa-Eurasia), microcontinents (e.g. Madagascar or New Zealand), or subcontinents (e.g. South Asia). Seven landmasses and their associated islands are commonly reckoned as continents, but these may be consolidated. For example, North and South America are often considered a single continent, and Asia is often united with Europe. Ignoring cases where Antarctica is omitted, or where Australasia or Oceania are used in place of Australia, there are half a dozen traditions for naming the continents.
