Isthmus
Explanation
Geographical landforms are defined by their physical composition and their spatial relationship with surrounding land or water bodies. Specific terms distinguish between features that connect landmasses versus those that connect water bodies.- Strait is Incorrect: A Strait is a narrow passage of water connecting two larger bodies of water. For example, the Palk Strait connects the Bay of Bengal and the Palk Bay.
- Isthmus is Correct: An Isthmus is a narrow strip of land with water on either side, connecting two larger landmasses. A prominent example is the Isthmus of Panama, which connects North America and South America.
- Peninsula is Incorrect: A Peninsula is a piece of land almost entirely surrounded by water or projecting into a body of water, but connected to the mainland on one side (e.g., the Indian Peninsula).
- Island is Incorrect: An Island is a tract of land surrounded entirely by water and is smaller than a continent.
Key Takeaway: An Isthmus connects two landmasses and separates two water bodies, whereas a Strait connects two water bodies and separates two landmasses.
