When are there high tides and low tides in Beidaihe?
When the sea ebbs, the water inside does not disappear, but flows back to the depths of the ocean. At low tide, seawater will slowly flow back to the depths of the ocean from the gap between the beach and the rocks. This flow is due to the fact that the seawater comes up at high tide and carries a lot of sediment, and these impurities will be brought back to the seabed at low tide.
Causes of high tide and low tide
1 first of all, we should know that the high tide and low tide of seawater are caused by the gravity of the moon and the sun. The moon is the natural satellite of the earth. It revolves around the earth. Due to the gravity of the moon, there will be a high tide on one side of the moon and a low tide on the opposite side of the moon. This is the phenomenon of high tide and low tide. At the same time, the sun's gravity will have a similar effect on the earth, but this effect is much smaller than that of the moon.
Secondly, we need to understand that after the low tide, the seawater did not disappear or be sucked away, but flowed back to the depths of the ocean. In fact, the flow of seawater is caused by natural force fields such as earth rotation and gravity. When the high tide of seawater is over, the water in the deep ocean will flow along the seabed to the place near the low tide line, and finally form a low tide. Therefore, the phenomenon of high tide and low tide is the result of seawater under the action of earth rotation and natural force field.
3. Besides the gravitational factors of the moon and the sun, the high tide of seawater is also influenced by other factors. Such as wind, ocean currents, seasons, etc. Will affect the ebb and flow of seawater. When the wind speed is high and the wind direction changes rapidly, there will be big waves, which will affect the range of high tide and low tide of seawater. Seasons also have an impact on the fluctuation of seawater. For example, rising temperatures will cause glaciers to melt, which in turn will lead to rising sea levels.
