16 Lunar Tide Fun Facts
What do you know about lunar tides? Lunar tides are created because the Earth and the moon are attracted to each other. The moon tries to pull Earth towards it, however, the Earth is able to hold everything into place except the water. This movement of the water is what we call high tide and low tide. In today's blog, Big Bags USA® thought it would be fun to share with you some interesting facts about lunar tides!
Tides are the periodic rising and falling of large bodies of water. Keep reading to learn more about how tides work with these fun facts!
1. The theory that tides were caused by the moon was introduced in 150 B.C. by Seleucus of Seleucia.
2. Isaac Newton was the first to explain tides with gravity related to the sun, earth and moon.
3. The gravitational force of the moon is one ten-millionth that of Earth, but when you combine forces such as the Earth's centrifugal force created by its spin, you get tides.
4. The sun's gravitational force on the Earth is only 46% that of the moon, making the moon the single most important factor for the creation of tides.
5. The sun's gravity also produces tides, but since the forces are smaller, as compared to the moon, the effects are greatly decreased.
6. Tides are not caused by the direct pull of the moon's gravity. The moon is pulling upwards while the water on the Earth is pulling downward; with the slight advantage of the moon, tides are created.
7. Whenever the moon, Earth and sun are aligned, the gravitational pull of the sun adds to that of the moon causing maximum tides.
8. Spring tides happen when the sun and moon are on the same side of the Earth (New Moon) or when the sun and moon are on opposite sides of the Earth (Full Moon).
9. When the moon is at first quarter or last quarter phase, meaning that it is located at right angles to the Earth/sun line), the sun and moon interfere with each other in producing tidal bulges and the tides are generally weaker. These are called neap tides.
10. Spring tide and neap tide levels are about 20% higher or lower than average.
11. Offshore, in the deep ocean, the difference in tides is usually less than 1.6 feet.
12. The surf grows when it approaches a beach, and the tide increases. In bays and estuaries, this effect is amplified.
13. The highest tides in the world are at the Bay of Fundy in Nova Scotia, Canada, at approximately 15 meters.
14. Most places in the ocean experience two high tides and two low tides each day. However, there are places that experience only one each day, dependent upon the shape of the coastline and the shape of the ocean floor.
15. Since the moon moves around the Earth, it's not always in the same place at the same time each day. So, each day, the times for high and low tides change by 50 minutes.
16. The type of gravitational force that causes tides is known as "tractive" force.
In a previous blog, we discussed How the Moon Affects Tides and therefore, how the moon affects flooding and flood risks. In coastal communities, it's common for spring tides to cause flooding in low-lying areas. When combined with strong winds, rainfall and storms, these tides can cause extensive flood damage. When it comes to preparing for coastal flooding, Big Bags USA® is your solution. Our flood barriers are a fast simple solution for containment and deferment of flood waters. They are great to have on hand in the event of a flooding disaster. Big Bags USA® flood barriers deployed as berm barriers and tidal breaks can use the coastal fronts' existing sand to fill the sandbags, providing even more savings while eliminating further sediment deposits.
