Island vs. Continent: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on November 23, 2023
An island is a landmass completely surrounded by water, smaller than a continent, which is a vast, continuous area of land on Earth.

Key Differences

Islands are smaller landmasses surrounded by water, while continents are the Earth's largest landmasses, making up the major parts of the globe.
Islands can be formed through volcanic activity, sediment accumulation, or coral build-up, whereas continents are established large land areas distinguished by geology and geography.
Islands are often isolated ecosystems with unique flora and fauna, in contrast to continents which have a wide variety of ecosystems and large, diverse populations.
Continents are integral to global geography, often defining regions and climates, while islands are more localized and can vary greatly in size and characteristics.
The concept of an island conveys a sense of separation or isolation, whereas a continent is associated with vastness and a wide expanse of land.
