Cape vs. Island: What's the Difference?
Edited by Janet White || By Harlon Moss || Updated on November 6, 2023
A cape is a pointed piece of land that sticks out into a sea, ocean, lake, or river; an island is a piece of land surrounded by water.
Key Differences
A cape is a high point of land that extends into a river, lake, or ocean, typically less substantial in land mass than an island. An island, by contrast, is a body of land completely surrounded by water and can support a wide range of habitats and ecosystems.
While a cape is a specific geographical feature marked by its prominent extension into water, creating a distinct point or headland, an island is an isolated landform that can range from a small islet to a large landmass like Greenland.
Both capes and islands can be significant for navigation; capes serve as markers for coastal navigation, whereas islands might be waypoints or destinations in oceanic travel.
The formation of a cape is typically the result of differential erosion, with the harder rock remaining to jut into the water, while islands can be formed through volcanic activity, sediment build-up, or rising sea levels.
Despite their differences, both capes and islands are often characterized by their unique flora and fauna, shaped by the forces of isolation and exposure.
