When will the tide rise and fall today?

At 6: 00 a.m. and 6:5438+08:00 p.m., the tide level rises to the highest, and ebbs at 6:5438+02:00 p.m. and 0:00 a.m.

Introduction to climax:

High tide is a natural phenomenon. There are high tides and low tides in seawater. At high tide, the sea rises, the waves roll and the scenery is spectacular. At low tide, the sea receded quietly, revealing a beach. High tide and low tide are usually twice a day.

The fluctuation of sea water is called tide during the day and sunseeker at night, so it is also called tide. China's ancient book says that the water in the sea is like tide in the morning and like sunseeker at night. There is a period between high tide and low tide when the water level does not rise or fall, which is called flat tide.

Brief introduction of low tide:

Low tide usually refers to the process of the sea surface falling from high tide to low tide. The cause of low tide is related to both the moon and the sun. When the sea level drops to the lowest position, the sea level is in equilibrium for a short time and the tide stops.

Reasons for low tide:

The reason of low tide is related to both the moon and the sun, that is, it is often heard that tidal force comes from the moon and the sun's attraction to the earth. Tidal force is an integral force, which is not completely determined by the gravity. However, because the earth is so big, the gravity borne by different parts of the earth is not exactly the same in magnitude and direction, and there are "force difference" and "direction difference", which are two differences that cause tidal force.

The characteristic of tidal force is that the star is stretched in the direction of gravity and compressed in the direction perpendicular to gravity, which is how the tides on the earth come.
