The periodic rises and falls of command are carried tides. They occur approximately every 24 hours. They are caused by the gravitational pull of the moon and sun on Earth's oceans. The Sun's gravitational pull, although greater than that of the Moon, has a smaller effect on the tides due to its distance from the Earth. The Moon's closer proximity to Earth, on the other hand, has a more significant effect on the tides. Therefore, the tides and the moon have a fairly important relationship.
In this article we are going to tell you everything you need to know about the tides and the moon and how it affects the sea.
The tides and the moon
As the Earth rotates, the gravitational force pulls water toward the side facing the Moon, causing a high tide. At the same time, water on the opposite side of the Earth is also swept away, causing another high tide. When the water recedes, low tide occurs.
Tides are regular fluctuations in ocean level, caused by the gravitational pull of the Sun and Moon relative to the Earth. This fact causes the migration of immense masses of water across the Earth's surface, since they are influenced by the celestial bodies in our vicinity. The gravitational pull of the Moon is approximately 2-3 times more powerful than that of the Sun, since the Moon is located much closer to the Earth.
The formation of tides takes place deep in the oceans, causing their impact to spread outward and affect coastlines around the world, resulting in the ebb and flow of the sea. The oceans contain enormous masses of water that move as a result of gravity.
The movement of water towards the coast is known as "flow", while water returning to the sea due to the gravitational pull of the Sun and mainly the Moon is called "ebb". This constant cycle of water movement creates what we call tides, which is the continuous coming and going of water on the coasts. This cycle creates two high tides and two low tides each day, causing two flows of water towards the coast and two ebbs of water towards the sea. Ultimately, the ebb and flow of water is the main driving force behind tides.
Newton, the tides and the moon
Isaac Newton's contributions to science are widely recognized, with his work on gravity and tidal science being of particular interest. Newton's groundbreaking theories of gravity not only formed the basis of modern physics, but also helped us understand the mechanics of the solar system and celestial movements. His studies in tidal science, which explored the complex interactions between the Moon and Earth's oceans, led to new insights into the behavior of tides and their patterns. Newton's work remains a fundamental part of scientific knowledge to this day.
The explanation of the tides lies in the principles established by Newton's laws. The law of gravitational attraction between the Earth, the Sun and the Moon is mainly based on the force of gravity. Newton postulated that the attraction between two objects is proportional to their mass and inversely proportional to the square of the distance between them.
To put it another way, the gravitational attraction between two objects is stronger when their masses are greater and when they are closer. The Moon's path around the Earth is elliptical, just as our orbit around the Sun is also elliptical. As for the Moon, the side of the Earth facing it experiences a stronger gravitational pull due to its proximity to the satellite.
This results in large amounts of water being drawn towards it, causing high tides. In contrast, the opposite side experiences a weaker gravitational pull due to the centrifugal force of the Earth relative to the Moon, resulting in a lower intensity high tide.
When using Newton's formula, it is important to recognize that distance plays a larger role than mass in calculating the gravitational force between two bodies. As a result, the attractive force exerted by the Moon is 2 to 3 times greater than that of the Sun, despite the latter's larger size. Consequently, lunar tides exhibit a greater degree of strength compared to solar tides.
High tide and low tide
The phenomenon of high and low tides is a natural phenomenon that occurs due to the gravitational attraction of the moon and the sun on the Earth's oceans. During high tide, the water level is at its highest point, while during low tide, it is at its lowest point. This pattern It is cyclical and occurs twice a day, with around six hours between each high and low tide. It is an essential aspect of coastal ecosystems and plays a crucial role in regulating marine life and coastal erosion.
The highest point the sea reaches is known as high tide. This occurs twice a day, with an interval of 12 hours and 25 minutes between each appearance. Low tide, or the lowest point the sea reaches, also occurs twice a day, with the same time interval as high tide. The duration of the half-tide period, which is the time span between high tide and low tide, It is 6 hours, 12 minutes and 30 seconds. As a result, the tide changes every day for approximately 50 minutes.
Surf schools are based on a reference point that lasts about 45-50 minutes to set your times for the next day's surf courses in relation to appropriate tidal conditions and the moon. This method is used because each beach has an ideal tidal point for surfing. On the other hand, divers should be aware of when high tide occurs and when the water begins to ebb, as the force of the ocean can pull them into deeper waters. Therefore, diving during low tide is recommended. Likewise, low tide is an opportune time for many anglers to go fishing, especially during periods of spring tide.
I hope that with this information you can learn more about the tides and the moon.
