Strait is a narrow passage of water that connects two larger bodies of water. It is usually located between two landmasses, such as continents or islands. Water flows through a strait, linking seas or oceans together. Straits can be important routes for ships.

Straits are found around the world, such as the Strait of Gibraltar between Europe and Africa. They exist as part of Earth’s geographic features. Straits are important for marine travel and trade. They also support marine ecosystems.
