How Is The Border Between Europe And Asia Defined?
Transcontinental countries, mountains, and rivers are part of the physical border between Asia and Europe. However, political factors also play a part in its definition.
Boundaries between continents are somewhat a matter of geographical convention. The number of continents that the Earth is considered to have can range between six or seven, although the count can go as low as four when Afro-Eurasia and Americas are combined as continents. There are only three overland boundaries in existence. These boundaries include the ones between Asia and Europe, between Africa and Asia, and between North and South America.
