Here are some intriguing facts about ocean tides

1. Tidal Waves: Tides are very large, long waves that travel around the world at an astonishing speed of 450 miles per hour. They have no beginning or end. The familiar 12-hour gradual rise and fall we observe on the beach is actually the passage of this tidal wave, first its crest and then its trough.
2. Water Wells and Tides: Water wells located as far inland as Wisconsin can fluctuate their water production based on tides. During flood tides, they produce more water, while during ebb tides, they yield less.
3. Moses and the Red Sea: The biblical account of Moses parting the Red Sea might have been a perfectly timed tidal event. Moses, living near the Red Sea, could have known that an extreme spring tide would create a dry passage across. As the Children of Israel crossed, the tide would rush back in, potentially catching Pharaoh’s army halfway across.
4. Tidal Energy Potential: The ocean’s tides hold an incredible amount of energy—about three Terawatts, which is three times the world’s daily energy consumption.
5. Earth’s Rotation and Tides: Tides create significant friction by rubbing against the ocean floor. While some of this energy dissipates as heat, most of it acts as a brake on the Earth’s rotation. Over time, the Earth is turning slower, and our days are growing longer due to tidal effects.
6. Tide Chart Cycles: Tide charts repeat themselves approximately every 18.6 years.
7. Galileo and Tides: Galileo’s book, originally titled “The Flux and Reflux of the Sea,” used the sloshing of ocean tides as evidence that the Earth moved. Although his tide theory was incorrect, it led to his house arrest by the Catholic Church.
8. Leonardo da Vinci’s Theory: In the 13th century, Leonardo da Vinci believed tides were caused by the breathing of a giant beast and even attempted to calculate the size of its lung.
9. Tidal Resonance and the Moon: The oceans resonate with vibrations from the moon and sun, similar to how a guitar body resonates when a string is plucked. Strong tidal resonance in Earth’s early history may have even thrown a piece of Earth into space, which became our moon.

Tides are a fascinating natural phenomenon, shaped by gravitational forces and the Earth’s rotation. 🌊🌍🌕²³⁴⁵
