What is Strait?
A Strait is a naturally formed navigable narrow passage of water connecting two seas or two large water bodies. It is a slim channel of water that lies between two landmasses. Below is the table that shows important straits of the world. As 90% of the trade takes place through sea routes, these straits provide navigable routes to various ships. For example, the Strait of Hormuz is very important as the world's one-third oil trade takes place through this strait. Straits are also used to generate tidal power using turbines, for instance, Cook's strait in New Zealand generates 5.6 GW of energy.
Difference between Strait & Isthmus:
- Many students get confused between a strait & an isthmus.
- A strait lies between two land masses connecting two larger water bodies, while an isthmus lies between two water bodies connecting two larger land masses.
