What is the difference between State and continent?

Answer 1

A state is a political unit. The boundaries of a state are a matter of international agreement (or international dispute) rather than being determined by geological features. A continent is a geological unit. It is a large land mass surrounded by the ocean.

Answer 2

A state is a political unit within a country, typically with its own government and administrative boundaries. A continent, on the other hand, is a large landmass on Earth, such as North America or Africa, defined by geographical and cultural characteristics. States can exist within continents as smaller subdivisions.
