Have you ever wondered why the sea always comes in and goes when you walk by the sea? This miraculous phenomenon is what we call "tides". But have you ever wondered where the low tide water goes?
In fact, high and low tides are a natural phenomenon in the ocean, mainly affected by the gravitational pull of the Moon and the Sun. When the Moon and the Sun are located in different positions on the Earth, their gravitational effects on seawater will also be different, resulting in changes in high and low tides.
When the moon is closest to the Earth, the water is affected by its gravitational pull and "uplifts" upwards, and a high tide is formed. On the opposite side, due to the weaker gravitational pull of the Moon, the sea water will also form another high tide here. That's why we have two places on Earth at the same time with high tides.
When the Earth turns to the other side of the Moon's gravity, the sea water will gradually recede, which is what we call low tide. So, where does the low tide water go? In fact, it did not disappear, but temporarily flowed to deeper seas. These seawaters form new tide levels elsewhere on Earth, after which they return to shore as the tides change.
In addition to the gravitational pull of the moon, the gravitational pull of the sun is also not negligible. Although the sun is farther away from us, its influence on the tides is also evident due to its sheer size. During the full moon or new moon, the gravitational pull of the sun and the moon is superimposed, and the rise and fall of the tide will be more obvious, which is what we often call the great tide; In a quarter of a month, the gravitational pull of the Sun and Moon cancels each other out, and the tide is relatively small, in which case a small tide is formed.
Many people think that low tide means that the sea water disappears, but in fact it is just a natural cycle. Every change of tide is the result of a tug-of-war between the earth, the moon and the sun, and is an elegant rhythm in nature.
So, the next time you're at the beach, stop and watch the high and low tides change and feel the wonder and harmony of this natural phenomenon. Behind every drop of seawater, there is the interaction of countless cosmic forces. Let's embrace the sea and understand its mysteries more deeply!
