Correct Option
The correct option is Bay of Fundy, Canada.
Explanation
Tides are the rhythmic rise and fall of ocean water that occur twice a day, primarily due to the gravitational attraction of the moon and the sun. The height and range of tides are significantly influenced by the configuration of the coastline, the depth of the water, and the shape of the bays or estuaries involved.
Detailed Analysis
The highest tides in the world occur in the Bay of Fundy, located in Nova Scotia, Canada.
- Tidal Range: The tidal range (the difference between high and low tide) in the Bay of Fundy is approximately 15 to 16 meters.
- Geographical Factors: This extreme tidal range is caused by two main factors:
- Funnel Shape: The bay is funnel-shaped, meaning it is wide at the mouth and narrows progressively inland. As the tidal wave enters the bay, the water is constricted into a smaller area, forcing it to rise higher.
- Resonance: The natural period of oscillation of the water in the bay is nearly identical to the period of the tidal cycle (approximately 12.4 hours). This resonance amplifies the tidal effect, similar to pushing a swing at the right moment.
- Comparison: While the Bay of Bengal, Gulf of Mexico, and North Sea experience tidal variations, their ranges are significantly lower than the extreme values observed in the Bay of Fundy. For instance, the Gulf of Mexico typically experiences very small tidal ranges (diurnal tides).
Key Takeaway: The Bay of Fundy in Canada records the highest tides in the world due to its unique funnel-shaped topography and tidal resonance.
